Many of the assessment activities will be based on the real events of the Piper Alpha oil rig incident Information and videos on Piper Alpha is easily accessed via the internet, libraries, and other sources. The following timeline and information on Piper Alpha was sourced form Wikipedia as open source information on February 21 2011 under the Creative Comments Deed. Information on the Creative Comments Deed can be sourced at http://creativecommons. org/licenses/by-sa/3. 0/ PIPER ALPHA Piper Alpha was a North Sea oil production platform operated by Occidental Petroleum (Caledonia) Ltd. The platform began production in 1976, first as an oil platform and then later converted to gas production. An explosion and resulting fire destroyed it on July 6, 1988, killing 167 men, with only 59 survivors.

The death toll includes two crewmen of a rescue vessel. [4] Total insured loss was about ? 1. 7 billion (US$ 3. 4 billion). At the time of the disaster the platform accounted for approximately ten percent of North Sea oil and gas production, and was the worst offshore oil disaster in terms of lives lost and industry impact. Thirty bodies were not recovered. Piper oil field Four companies that later transformed into the OPCAL joint venture obtained an oil exploration licence in 1972 and discovered the Piper oilfield located at 58°28? N 0°15? E? / ? 58. 467°N 0. 25°E? / 58. 467; 0. 25 in early 1973 and commenced fabrication of the platform, pipelines and onshore support structures.

Oil production started in 1976 with about 250,000 barrels of oil per day increasing to 300,000 barrels (48,000 m3). A gas recovery module was installed by 1980. Production declined to 125,000 barrels (19,900 m3) by 1988. OPCAL built the Flotta oil terminal in the Orkney Islands to receive and process oil from the fields Piper, Claymore and Tartan, each with its own platform. One thirty inch (0. 762 m) diameter main oil pipeline ran 128 miles (206 kilometres) from Piper Alpha to Flotta, with a short oil pipeline from the Claymore platform joining it some twenty miles (32 km) to the west. The Tartan field also fed oil to Claymore and then onto the main line to Flotta.

Separate 46 cm diameter gas pipelines run from Piper to the Tartan platform, and from Piper to the gas compressing platform MCP-01 some 30 miles (48 km) to the Northwest. Construction A large fixed platform, Piper Alpha was situated on the Piper oilfield, approximately 120 miles (193 km) northeast of Aberdeen in 474 feet (144 m) of water, and comprised four modules separated by firewalls. The platform was constructed by McDermott Engineering at Ardersier and UIE at Cherbourg, with the sections united at Ardersier before tow out during 1975, with production commencing in late 1976. For safety reasons the modules were organised so that the most dangerous operations were distant from the personnel areas.

The conversion from oil to gas broke this safety concept, with the result that sensitive areas were brought together, for example the gas compression next to the control room, which played a role in the accident. It produced crude oil and natural gas from 24 wells for delivery to the Flotta oil terminal on Orkney and to other installations by three separate pipelines. It has been said[by whom? ] that at the time of the disaster, Piper was one of the heaviest platforms (along with Magnus and Brae B), operating in the North Sea. Timeline of the incident A new gas pipeline was built in the weeks before the 6 July explosion, and while this work disrupted the normal routine, the platform was operating as normal. The discovery of a small gas leak was not unusual and no cause for concern.

Because the platform was completely destroyed, and many of those involved died, analysis of events can only suggest a possible chain of events based on known facts. Some witnesses to the events question the official timeline. 12:00 p. m. Two condensate pumps, designated A and B, displaced the platform’s condensate for transport to the coast. On the morning of July 6, Pump A’s pressure safety valve (PSV #504) was removed for routine maintenance. The pump’s fortnightly overhaul was planned but had not started. The open condensate pipe was temporarily sealed with a blind flange (flat metal disc). Because the work could not be completed by 6:00 p. m. , the blind flange remained in place.

The on-duty engineer filled out a permit which stated that Pump A was not ready and must not be switched on under any circumstances. 6:00 p. m. The day shift ended, and the night shift started with 62 men running Piper Alpha. As he found the on-duty custodian busy, the engineer neglected to inform him of the condition of Pump A. Instead he placed the permit in the control centre and left. This permit disappeared and was not found. Coincidentally there was another permit issued for the general overhaul of Pump A that had not yet begun. 7:00 p. m. Like many other offshore platforms, Piper Alpha had an automatic fire-fighting system, driven by both diesel and electric pumps (the latter were disabled by the initial explosions).

The diesel pumps were designed to suck in large amounts of sea water for fire fighting; the pumps had an automatic control to start them in case of fire. However, the fire-fighting system was under manual control on the evening of July 6: Piper Alpha procedures required manual control of the pumps whenever divers were in the water (as they were for approximately 12 hours a day during summer) regardless of their location, to prevent divers from being sucked in with the sea water (fire pumps on other platforms were switched to manual control only if the divers were close to the inlet). 9:45 p. m. Condensate (natural gas liquids NGL) Pump B stopped suddenly and could not be restarted.

As the entire power supply of the offshore construction work depended on this pump, the manager had only a few minutes to bring the pump back online, otherwise the power supply would fail completely. A search was made through the documents to determine whether Condensate Pump A could be started. 9:52 p. m. The permit for the overhaul was found, but not the other permit stating that the pump must not be started under any circumstances due to the missing safety valve. The valve was in a different location from the pump and therefore the permits were stored in different boxes, as they were sorted by location. None of those present was aware that a vital part of the machine had been removed.

The manager assumed from the existing documents that it would be safe to start Pump A. The missing valve was not noticed by anyone, particularly as the metal disc replacing the safety valve was several metres above ground level and obscured by machinery. 9:55 p. m. Condensate Pump A was switched on. Gas flowed into the pump, and because of the missing safety valve, produced an overpressure which the loosely fitted metal disc did not withstand. [9] Gas audibly leaked out at high pressure, drawing the attention of several men and triggering six gas alarms including the high level gas alarm, but before anyone could act, the gas ignited and exploded, blowing through the firewall made up of 2. 5 x 1. metre panels bolted together, which were not designed to withstand explosions. The custodian pressed the emergency stop button, closing huge valves in the sea lines and ceasing all oil and gas production. Theoretically, the platform would then have been isolated from the flow of oil and gas and the fire contained. However, because the platform was originally built for oil, the firewalls were designed to resist fire rather than withstand explosions. The first explosion broke the firewall and dislodged panels around Module (B). One of the flying panels ruptured a small condensate pipe, creating another fire. 10:04 p. m. The control room was abandoned.

Piper Alpha’s design made no allowances for the destruction of the control room, and the platform’s organisation disintegrated. No attempt was made to use loudspeakers or to order an evacuation. Emergency procedures instructed personnel to make their way to lifeboat stations, but the fire prevented them from doing so. Instead the men moved to the fireproofed accommodation block beneath the helicopter deck to await further instructions. Wind, fire and smoke prevented helicopter landings and no further instructions were given, with smoke beginning to penetrate the personnel block. As the crisis mounted, two men donned protective gear in an attempt to reach the diesel pumping machinery below decks and activate the firefighting system. They were never seen again.

The fire would have burnt out were it not being fed with oil from both Tartan and the Claymore platforms, the resulting back pressure forcing fresh fuel out of ruptured pipework on Piper, directly into the heart of the fire. The Claymore continued pumping until the second explosion because the manager had no permission from the Occidental control centre to shut down. Also, the connecting pipeline to Tartan continued to pump, as its manager had been directed by his superior. The reason for this procedure was the exorbitant cost of such a shut down. It would have taken several days to restart production after a stop, with substantial financial consequences. Gas lines of 140 to 146 cm in diameter ran to Piper Alpha. Two years earlier Occidental management ordered a study, the results of which warned of the dangers of these gas lines.

Due to their length and diameter it would have taken several hours to reduce their pressure, so that it would not have been possible to fight a fire fuelled by them. Although the management admitted how devastating a gas explosion would be, Claymore and Tartan were not switched off with the first emergency call. 10:20 p. m. Tartan’s gas line (pressurised to 120 Atmospheres) melted and burst, releasing 15-30 tonnes of gas every second, which immediately ignited. A massive fireball 150 metres in diameter engulfed Piper Alpha, killing two crewmen on a fast rescue boat launched from the standby vessel Sandhaven and the six Piper Alpha crewmen they had rescued from the water. 10] From that moment on, the platform’s destruction was assured. 10:30 p. m. The Tharos, a large semi-submersible fire fighting, rescue and accommodation vessel, drew alongside Piper Alpha. The Tharos used its water cannons where it could, but it was restricted because the cannons were so powerful they would injure or kill anyone hit by the water. 10:50 p. m. The second gas line ruptured, spilling millions of litres of gas into the conflagration. Huge flames shot over 300 ft (90 m) in the air. The Tharos was driven off by the fearsome heat, which began to melt the surrounding machinery and steelwork. It was only after this second explosion that the Claymore stopped pumping oil.

Personnel still left alive were either desperately sheltering in the scorched, smoke-filled accommodation block or leaping from the deck some 200 ft (60 m) into the North Sea. 11:20 p. m. The pipeline connecting Piper Alpha to the Claymore Platform burst. 11:50 p. m. The generation and utilities Module (D), which included the fireproofed accommodation block, slipped into the sea. The largest part of the platform followed it. 12:45 a. m. , July 7 The entire platform had gone. Module (A) was all that remained of Piper Alpha. At the time of the disaster 224 people were on the platform; 165 died and 59 survived. ] Two men from the Standby Vessel Sandhaven were also killed.

Aftermath There is controversy about whether there was sufficient time for more effective emergency evacuation. People were still getting off the platform several hours after the initial fires and explosions. The main problem was that most of the personnel who had the authority to order evacuation had been killed when the first explosion destroyed the control room. This was a consequence of the platform design, including the absence of blast walls. Another contributing factor was that the nearby connected platforms Tartan and Claymore continued to pump gas and oil to Piper Alpha until its pipeline ruptured in the heat in the second explosion.

Their operations crews did not believe they had authority to shut off production, even though they could see that Piper Alpha was burning. The nearby diving support vessel Lowland Cavalier reported the initial explosion just before 22:00, and the second explosion occurred twenty two minutes later. By the time civil and military rescue helicopters reached the scene, flames over one hundred metres in height and visible as far as one hundred km (120 km from the Maersk Highlander) away prevented safe approach. Tharos, a specialist firefighting vessel, was able to approach the platform, but could not prevent the rupture of the Tartan pipeline, about two hours after the start of the disaster, and it was forced to retreat due to the intensity of the fire.

Two crewmen from the standby vessel MV Sandhaven Fast Rescue Craft were killed when an explosion on the platform destroyed their Fast Rescue Craft; the survivor Ian Letham later received the George Medal. The largest number of survivors (37 out of 59) were recovered by the Fast Rescue Craft MV Silver Pit; coxswain James Clark later received the George Medal. Others awarded the George Medal were Charles Haffey from Methil, Andrew Kiloh from Aberdeen, and James McNeill from Oban. The blazing remains of the platform were eventually extinguished three weeks later by a team led by famed firefighter Red Adair, despite reported conditions of 80 mph (130 km/h) winds and 70-foot (20 m) waves. 13] The part of the platform which contained the galley where about 100 victims had taken refuge was recovered in late 1988 from the sea bed, and the bodies of 87 men were found inside The night the sea caught fire: Remembering Piper Alpha. Legacy of accident The Cullen Inquiry was set up in November 1988 to establish the cause of the disaster. In November 1990, it concluded that the initial condensate leak was the result of maintenance work being carried out simultaneously on a pump and related safety valve. The enquiry was critical of Piper Alpha’s operator, Occidental, which was found guilty of having inadequate maintenance and safety procedures. But no criminal charges were ever brought against it.

The second phase of the enquiry made 106 recommendations for changes to North Sea safety procedures, all of which were accepted by industry. Most significant of these recommendations was that the responsibility for enforcing safety in the North Sea should be moved from the Department of Energy to the Health and Safety Executive, as having both production and safety overseen by the same agency was a conflict of interest. The disaster led to insurance claims of around US$ 1. 4 billion, making it at that time the largest insured man-made catastrophe. The insurance and reinsurance claims process revealed serious weaknesses in the way insurers at Lloyd’s of London and elsewhere kept track of their potential exposures, and led to their procedures being reformed.

Survivors and relatives of those who died went on to form the Piper Alpha Families and Survivors Association, which campaigns on North Sea safety issues. Beginning in 1998, one month after the tenth anniversary, Professor David Alexander, director of the Aberdeen Centre for Trauma Research at Robert Gordon University carried out a study into the long-term psychological and social effects of Piper Alpha. He managed to find thirty-six survivors who agreed to give interviews or complete questionnaires. Almost all of this group reported psychological problems. More than 70% of those interviewed reported psychological and behavioral symptoms of post traumatic stress disorder.

Twenty-eight said they had difficulty in finding employment following the disaster; it appears that some offshore employers regarded Piper Alpha survivors as Jonahs – bringers of bad luck, who would not be welcome on other rigs and platforms. The family members of the dead and survived victims also reported various psychological and social problems. Alexander also wrote that “some of these lads are stronger than before Piper. They’ve learned things about themselves, changed their values, some relationships became stronger. People realised they have strengths they didn’t know they had. There was a lot of heroism took place.

The goal of all occupational health and safety programs is to foster a safe work environment. en. wikipedia. org/wiki/Occupational_health_and_safety Is another way of saying ‘Health and Safety at Work’. It’s about preventing disease or injury that is a direct result of your workplace. www. safehands. ie/glossary. htm It’s better to deal with health and safety issues before they become a problem – a planned approach to safety is essential for your business. Safety shouldn’t be seen as an additional cost – it is a necessary and essential component of your business. Under OHS legislation you are obliged to provide: • safe premises • safe machinery and materials safe systems of work • information, instruction, training and supervision • a suitable working environment and facilities. If you don’t comply with these legal requirements you can be prosecuted and fined. Workplace health and safety authorities in each state and territory and Safe Work Australia have responsibilities for enforcing the OHS legislation. They provide information and advice on safety and health at work and education and training. You can get information about your OHS obligations and other valuable OHS resources both in hard copy and online from their websites. Please note that legal obligations of employers vary according to circumstances.

You may wish to seek independent legal advice on what is applicable to your situation. www. business. gov. au OHS Acts, Regulations and Codes of Practice OHS Acts In Australia, states and territories have responsibility for making laws about occupational health and safety (OHS) and for enforcing those laws. Each state and territory has a principal OHS Act, setting out requirements for ensuring that workplaces are safe and healthy. These requirements spell out the duties of different groups of people who play a role in workplace health and safety. OHS Regulations and Codes of Practice Some workplace hazards have the potential to cause so much injury or disease that specific regulations or codes of practice are warranted.

These regulations and codes, adopted under state and territory OHS Acts, explain the duties of particular groups of people in controlling the risks associated with specific hazards. There is a difference between regulations and codes: • Regulations are legally enforceable. • Codes of Practice provide advice on how to meet regulatory requirements. Codes are not legally enforceable, but they can be used in courts as evidence that legal requirements have or have not been met. NEW NATIONAL WORKPLACE HEALTH AND SAFETY LAWS The model Work Health and Safety (WHS) Act  is the result of a comprehensive national review into work health and safety laws across Australia. Details of the Act can be found at http://www. comlaw. gov. au/Details/C2011A00137

Many States have already agreed to the harmonisation of workplace health and safety laws with details of how each state is undertaking this process available at the relevant website for each listed below.

Common law is based on sets of rules developed by judges usually hearing cases in superior courts. Common law is also referred to as case law and can be viewed as legal rules not contained in legislation. Statute law is legislation.

The word legislation refers to both statutes and delegated legislation such as regulations and by-laws. Statutes or acts are made by parliaments. The differences between common and statute law are important as Judges through the common law court system, could be seen as making decisions in order to resolve specific disputes between various parties. E. g. If a worker is injured at his/her workplace a court will decide on the question of blame and what compensation is owed. This is a reactive system of law. Legislation has the potential to be pro-active and may serve to prevent the worker from becoming injured in the first place. Legislation is much more flexible than common law and always takes precedence over it.

Parliament has the power to change any rules deriving from case law that may be considered undesirable. The courts play an important role in ensuring that legislative bodies follow proper procedures upon making legislation and are charged with the responsibility of resolving disputes which may arise over the meaning of words in the legislation. Source: Taylor Easter Hegney, (2001) Enhancing Safety A Workplace Guide 1 Third Edition Duty of care (level of responsibility) Under OHS legislation, organisations have certain legal obligations to their employees, contractors and clients. Individuals also have personal obligations as employees and in their work role.

These state-based legislated responsibilities derive from the duty of care to ensure a safe place of work, safe systems of work, and safe and adequate tools and equipment together with competent workers. Duty of care places into a legal form a moral duty to anticipate possible causes of injury and illness and to do everything reasonably practicable to remove or minimise these possible causes of harm. Many people in the workplace have a role in occupational health and safety. The individual roles are determined by the duty of care that has developed through common law and the legislated responsibilities that are based on common law but are rules determined by the parliament. The approach to responsibilities taken in both common law and the OHS legislation is that the responsibility sits with those who have the control.

The Board and the Manager have ultimate responsibility for occupational health and safety because they have the decision-making control. But the people who spend most time in safety-related activities are the supervisors and shop floor personnel. Occupational health and safety is a shared responsibility. Depending on your situation, there will be a number of people involved. These might include: • your workplace manager, coordinator or supervisor • a director of the organisation • the employer • the Health and Safety Advisor in your workplace • Human Resources personnel. Don’t forget, everyone has a role to play too but the level of their control may be minimal.

A work environment, whether it is a factory, classroom, shop floor or work placement, is also governed by that duty of care. Therefore, your organisation must recognise and act upon this duty of care. The level of responsibility can be represented by the following triangles. |Activities required to meet this responsibility may |[pic] | |be delegated but the responsibility itself cannot be| | |delegated. Thus, a manager may delegate activities | | |such as training to a supervisor, but they still | | |have the responsibility to ensure that the training | | |is actually conducted and is of an appropriate | | |standard. | | | | | |[pic] | | | | | | | | | | |Thus, the actual time involved in occupational | | |health and safety is not always relative to the | | |level of responsibility. Rather, it is shown by | | |turning the triangle back on its base. | NOTE: Volunteers and other non-paid workers are still covered by Workplace Health and Safety Legislation and organisations still have a duty of care and may be liable for workers compensation and or other payments. What are the roles of key OHS/WHS organisations? The main organisations that administer or are otherwise responsible for the functioning of the OHS Act and their roles are: Worksafe Australia – ‘To ensure that employer and employer associations, employees and trade unions and governments are involved in and support the common adoption of world best practice systems and national standards for workplace health and safety’.

WorkCover (This is the Victorian authority for an example of a State organisation) – ‘To improve workplace health and safety for workers, employers and the community by coordinating and supporting the delivery of prevention, rehabilitation and compensation services. ’ (Other State OHS organisations will have a similar role to this). ComCare – ‘To take a leading role in the reduction of the human and financial costs of workplace injury and, by working with their customers, prevent injuries and return injured employees to work’. What are the responsibilities of employer and employee? Every employer has a duty to each employee to ‘ensure so far as is reasonably practicable that the employee is, while at work, safe from injury and risks to health’. This includes taking action to control the risks that occur in the workplace.

Some of the detailed responsibilities of employers are: • Provide and maintain a safe working environment • Provide and maintain safe systems at work • Provide and maintain machinery, equipment, appliances, implements, tools and substances in a safe condition. Employees must take reasonable care to protect their own health and safety and the health and safety of others who may be affected by their actions or omissions at work. What are the roles of OHS committees, representatives and unions? OHS committees are a representative group within the workplace that provides a forum to discuss and resolve OHS matters. The general way they are formed and operate is: The people on the committee are elected by the group they are representing ? They allow management and employees to meet regularly to discuss and solve health and safety issues in their particular work location ? They allow the use of both the employees’ practical experience of risks in the workplace, and management’s knowledge of organisations and processes ? They can be used to decide local policies and procedures, and to resolve OHS/WHS disputes. OHS/WHS representatives are elected for a period of three years and they, or their employer, must notify the OHS/WHS Authority of their appointment so that they can be kept up to date on OHS/WHS matters as they occur.

Representatives can be involved in the following activities: ? Inspection of the workplace as a routine inspection or because of an accident or incident requiring immediate action ? Discuss problems or conduct investigations usually in company with management, other OHS/WHS committee members and/or a suitable consultant ? Accompany a Department of Industrial Relations (DIR) inspector during visits ? Obtain access to OHS/WHS information on activities and workers ? Investigate OHS/WHS complaints. The ‘Designated Work Group’ (DWG) is a small organisation within the workplace which can be established to represent their particular area, role or tasks. The groups operate in the following way: Trade unions work with employers to decide how many groups there should be in the workplace. The number of groups will depend on the size of the workplace and the types of work being carried out. ? Each DWG can elect one OHS/WHS representative. Elections are organised by the workplace union ? Not every DWG needs to have a representative, nor does a workplace need DWG’s. This is decided for each workplace depending on the needs agreed between management, unions and the workers. The relevant workplace unions also have a responsibility towards OHS/WHS. They assist in the monitoring of safe working practices and provide another avenue for any dispute resolution.

The union can also be involved in the running of elections for representatives and committees The three steps in accident prevention The three steps in accident prevention are: [pic] Remember, consultation is an important element of all three steps. The process used by organisations to identify, evaluate and control hazards is called risk management. Organisations have to continually: • identify hazards • assess the risk of illness and injury from the hazards • implement control measures to eliminate or mitigate the effects of the hazards. RISK MANAGEMENT (RM) Risk Management (RM) is a five step process for controlling exposure to health and safety risks associated with hazards in the workplace. The five steps in the process are: |[pic] | |STEP 1 – IDENTIFY HAZARDS | | | | | |STEP 2 – ASSESS RISKS | | | | | |STEP 3 – DECIDE ON CONTROL MEASURES | | | | | |STEP 4 – IMPLEMENT CONTROL MEASURES | | | | | |STEP 5 – MONITOR & REVIEW | |

In many cases risk management is nothing more than a careful examination of what could cause harm to people in your workplace and: • weighing up whether you have taken enough precautions or • should do more to prevent harm, and • controlling exposure to prevent harm. When undertaking risk management: • Involve workers in the process. • Don’t use it to justify a decision that has already been made. • Consider good practice in your industry. • Make records of any risk management activities undertaken. You can access information about OHS/WHS at (accessed January 2005). The way this process is implemented at your workplace will depend on the type of work undertaken and the nature of hazards and risks in the workplace.

Although this standard details each step in the process separately, in practice you may find that some steps overlap. For example, a single inspection of the workplace can allow identification of a hazard and assess the level of associated risk at the same time. When undertaking this process, try to be objective and practical. Consider what actually happens in the workplace, not only what a manual can specify should happen. Take advantage of existing control measures and make sure all relevant hazards are addressed. HIERARCHY OF HAZARD CONTROL [pic] Examples of workplace hazards Occupational hazards can be physical, chemical, biological, mechanical or psychological. The following table shows some examples of each of these types of hazard. Physical |Noise |Underfoot conditions | | |Hot or cold objects |Electricity | | |Hot or cold environments |Working in exposed weather conditions | | |Fluids under pressure |Vibration | | |Airborne particulates |Falling or flying objects | | |Mobile plant or load shifting equipment |Radiation | | |Machinery with moving parts |Sharp or cutting edges | |Chemical |Hazardous substances |Combustible materials | | |Dangerous goods |Fire | | |Hazardous atmosphere |Explosions | |Biological |Pathogens |Spiders, insects, snakes | | Microorganisms |Large animals | |Ergonomic |Manual handling |Fatigue | | |High repetition work practices |Work postures | |Psycho-social |Workload |Role clarification | | |Fatigue/shift work |Interpersonal relationships | WHAT IS A HAZARD A Hazard is anything that can cause harm, injury, damage, loss, incapacity, or death.

Following are various sites available to you, depending on which state or territory you work, providing information on hazards and their associated risks. • www. workcover. nsw. gov. au/… /HazardsWorkingEnvironment/… /default. aspx • www. education. vic. gov. au/[email protected]/workplace_hazards. asp • www. workplaceohs. com. au/Hazards. asp • www. deir. qld. gov. au/workplace/business/… /otherhaz • www. safework. sa. gov. au/… /IdentifyingHazards/stuHazardControl. htm • www. youngworkers. com. au/… /protecting_young_workers_from_workplace_hazards A hazard is anything with the potential to cause harm to life, health or property. For example, cluttered and unmarked walkways are a hazard in a workplace. They increase the risk of injury.

A hazard does not change from being a hazard because of location or circumstance: For example, a nail sticking out of a wall no matter where it is located is still a hazard. The difference is that a nail sticking out of the wall in a well-used doorway is more likely to cause someone injury than a nail sticking out of the wall near the ceiling. The likelihood of injury is different, but both are still hazards. What are physical hazards? A hazard can be defined as a situation that can be dangerous to people or can cause damage. Physical hazards are dangers in the workplace such as: o Noise and vibration o Extremes of temperature and humidity o The condition and design (ergonomics) of furniture and equipment The condition of the workplace, such as: o Congestion o Clutter o Waste material buildup o Poor lighting and visibility. How can chemical hazards be caused? Chemical hazards can be caused by: o Poor ventilation causing a risk from: o Gases – breathing in, touching the skin or from explosions o Fumes o Vapours o Dust o Liquids – from swallowing, slipping on spills or from liquids catching fire o Mineral fibres. What contributes to behavioral hazards? Behavioral hazards are caused by the way workers do their job. This applies to such things as attitude, concentration, and effort applied by the worker. The main things that contribute to behavioral hazards are: Improvisation, for example, taking ‘short cuts’ or using the wrong equipment to carry out tasks o Carelessness o Poor health – this affects judgement, strength and concentration o Incorrect techniques o Inexperience o Poor or no training. How can hazards be fixed or avoided? There are a number of ways that the hazards described above can be avoided or solved. For example: – Using safe working practices by: o Following the guidance given in OHS/WHS regulations and Codes of Practice o Knowing and using the information in procedures and operator manuals o Doing your work in an orderly way o Reporting, and correcting where possible, any activities that are a risk to workers. Workplaces should be laid out in a well planned way which would include: o Emergency equipment o First aid o Clearly marked exits o Marked walkways o Clear access and aisles o Guardrails o Signposts o Separate amenities. WHAT IS A RISK Risk is the probability (likelihood) that the hazard will actually result in injury or disease. For example, the probability of a sprained or broken limb is increased if walkways are cluttered and unmarked. A major role for supervisors in occupational health and safety is identifying hazards in the workplace and eliminating or minimising the risks they pose. Some hazards may be obvious and immediate in their effect. They may be simple to deal with, for example water on the floor.

But many hazards are ‘hidden’, for example dust, and therefore may take time to have an effect. So we need to identify the different types of hazards in the workplace. We do this by: ? Regular inspections ? Accident and sickness records ? Accident investigation. Risk control Risk is the probability that the hazard will actually result in injury or disease. Under the OHS/WHS legislation, you are required to introduce new control measures to eliminate the risk, or if that is not reasonably practicable, to reduce the risk so far as is reasonably practicable, if the current measures are found to be inadequate and there is a likelihood that injury, illness or disease will result from a particular situation.

The term “reasonably practicable” has a particular meaning under the OHS/WHS legislation. It means practicable having regard to: • The likelihood of a hazard or risk occurring (i. e. the probability of a person being exposed to harm); • The degree of harm that would result if the hazard or risk occurred (i. e the potential seriousness of injury or harm); • What the person concerned knows, or ought reasonably know, about the hazard or risk and any ways of eliminating or reducing that hazard or risk; • The availability and suitability of ways to eliminate or reduce the hazard or risk; and • The cost of eliminating or reducing the hazard or risk.

An extreme risk requires immediate action as the potential could be devastating to the organisation. High A high level of risk requires action, as it has the potential to be damaging to the organisation. Moderate Allocate specific responsibility to a moderate risk and implement monitoring or response procedures. Low Treat a low level of risk with routine procedures. THE WORKPLACE HEALTH AND SAFETY RISK MANAGEMENT PROCESS [pic] [pic] The risk control process must be carried out in consultation with the relevant health and safety representatives and employees. In identifying new risk control measures, the most effective form of control measures is to eliminate the risk (eg by eliminating the process).

If that is not reasonably practicable you need to identify effective measures to reduce the risk. The OHS/WHS legislation specifies that you must not depend solely on the use of administrative controls or personal protective equipment to reduce the risk unless that you have established that the following are not practicable measures: • Substituting the plant or substance with another one that is less hazardous • Using engineering controls (eg modifying the design of the workplace or plant, or environmental conditions) • Isolating people from the source of exposure • Changing the objects used in the task involving manual handling • Using mechanical aids for manual handling tasks

The way this process is implemented at your workplace will depend on the type of work undertaken and the nature of hazards and risks in the workplace. Although this standard details each step in the process separately, in practice you may find that some steps overlap. For example, a single inspection of the workplace can allow identification of a hazard and assess the level of associated risk at the same time. When undertaking this process, try to be objective and practical. Consider what actually happens in the workplace, not only what a manual can specify should happen. Take advantage of existing control measures and make sure all relevant hazards are addressed.

Before any decision is taken as to which type of risk control measures ought to be used, consideration should be given to the severity of injury, illness or disease that could occur. If the severity is high (i. e. fatality, serious injury etc), a higher hierarchy order of control (i. e. elimination, substitution, engineering controls, isolation) should be used. Sometimes they may have to be used in combination with administrative controls and in some cases personal protective equipment. It is not always reasonably practicable to immediately implement the higher hierarchy of control and there may still be a need to keep the process/activity going. In such situations interim control measures (in the
