Job Safety Analysis vs Risk Assessment

JSA and a (Qualitative) Risk Assessment (QRA) are different hazard and risk management tools. When you're doing a JSA, you are not, in fact, performing a risk assessment, which is a completely separate tool in risk management tool box.

In a JSA, the work team goes through a fairly simple analysis by breaking a job down into task-steps and then running through a six-step process to identify the following information: 1) the hazards in each step; 2) the triggers that could release the hazards; 3) the incidents that could occur in each step should the hazard be uncontrollably released; 4) the potential consequences of an uncontrolled hazard; 5) the prevention controls to be used to control the hazard; and 6) the mitigation and recovery controls to be used to manage any emergency and recover control over the hazard. I call the above process "Think 6, Look 6" to describe what workers need to do to complete a JSA!

In QRA, a team assesses the risk (likelihood) of any given incident (identified in step 3 above) occurring, that results in a given consequence (in step 4 above), and taking account of the controls being used (identified in steps 5 + 6). This assessment provides what we call the "residual" risk - the risk "left-over" once our controls are in place. The "raw" or inherent risk is assessed by simply not factoring in the use of controls.

Risk Control -- Hierarchy of Control

You will need to introduce preventative and protective measures to control the risks you have identified by your risk assessment.   To help you to identify the best way to control the risk, a ‘hierarchy of control measures’ has been developed.  You need to adopt solutions from the top of the hierarchy before considering those lower down.  The hierarchy begins with ‘elimination’, as eliminating the risk altogether will always be preferable to risk reduction. 

 1.  Elimination – if possible, avoid the risk altogether- For example, do the work in a different way, taking care not to introduce new hazards; use mechanical pile cropping techniques to avoid piling.

2. Substitution - you could substitute a dangerous product or tool for one, which is less dangerous.

3. Control the risk at source - For example using manual handling aids when lifting heavy objects; fitting local exhaust ventilation to dusty processes; mechanising the process so the person is separated from the hazard; changing the system of work to one which involves less manual handling

4. Education and Training  – ensure that workers and others understand the risk and know what they must do, for example by giving toolbox talks on health issues, or running through the method statement during induction training.

5. Personal Protective Equipment – this should only be used as a last resort as it is the least reliable form of protection.  Where PPE is provided, it should be made available free of charge; suitable for the individual; provided with suitable storage and cleaning arrangements and regularly checked to make sure it is in good condition.

 You should always give priority to those measures which protect the whole of the workplace and everyone who works there, i.e. give collective protective measures priority over individual protection).  Some control measures, such as choosing a safer alternative substance, will provide a high degree of control and are reliable.  Physical safeguards such as enclosing a hazardous process or providing local exhaust ventilation will need to be checked and maintained, and this imposes a longer-term cost.

 You should develop a coherent approach to your risk reduction program which will progressively reduce those risks which cannot be eliminated.  Where necessary, you should adopt a mix of the above protective measures in order to provide the best protection.

 Managing Risk Control Systems:

 The purpose of a ‘risk control system’ is to make sure that work place precautions are implemented and kept in place.  The greater the hazard or risk, the more robust and reliable the control system should be.

 You will need to decide what control systems are necessary.  Further advice on managing risk control systems can be found in the HSE publication HSG 65- Successful health and safety management, available from HSE Books, PO Box 1999, Sudbury, Suffolk CO100 6FS, Tel. 01787 881165.

What is OHSAS 18001?

Add caption

OHSAS 18000 is an international occupational health and safety management system specification. It comprises two parts, 18001 and 18002 and embraces a number of other publications.

For the record, the following other documents, amongst others, were
 used in the creation process:

-BS8800:1996 Guide to occupational health and safety management systems
-DNV Standard for Certification of Occupational Health and Safety Management Systems(OHSMS):1997
-Technical Report NPR 5001: 1997 Guide to an occupational health and safety management system
-Draft LRQA SMS 8800 Health & safety management systems assessment criteria
-SGS & ISMOL ISA 2000:1997 Requirements for Safety and Health Management Systems
-BVQI SafetyCert: Occupational Safety and Health Management Standard
-Draft AS/NZ 4801 Occupational health and safety management systems -Specification with guidance for      use
-Draft BSI PAS 088 Occupational health and safety management systems
-UNE 81900 series of pre-standards on the Prevention of occupational risks
-Draft NSAI SR 320 Recommendation for an Occupational Health and Safety (OH and S) Management  System

OHSAS 18001 is an Occupation Health and Safety Assessment Series for health and safety management systems. It is intended to help an organizations to control occupational health and safety risks. It was devloped in response to widespread demand for a recognized standard against which to be certified and assessed.

Central to OHSAS requirements are strong policies and procedures. To assist in this respect, we can therefore offer the following code of practice:

• Equipment is selected to be suitable for the intended purpose, particularly with regard to the site conditions in which the equipment will be used.
• Appropriate maintenance is carried out and any associated logs kept up to date.
• Specific Health and Safety risks associated with the equipment are considered and where appropriate:
  Use of the equipment is restricted to competent, nominated persons.
  Maintenance/Servicing is restricted to designated persons with the appropriate competence. 
• Persons who will use, supervise and manage equipment receive information and instruction on training to cover
  The conditions and circumstances in which the equipment may be safely used.

1.32 Hygienic Maintenance.
It is most important for all contractors, especially those engaged in maintenance operations who may be required to work in areas where computing equipment is being handled, to recognize that the way they organize and conduct their work can present a threat to the product. The threat arises from several sources:
A. Accidental contamination of the product or equipment by foreign bodies for example: flakes of paint, dust, nuts, bolts, screws, gaskets and "O" Rings etc.
B. Accidental contamination by failure to operate according to a reasonable code of practical hygiene.
C. Use of unsuitable materials to lubricate or otherwise treat the surfaces of equipment.
It is therefore essential that due consideration is given to the way the work is to be done before starting, so that adequate precautions are taken to prevent contamination from all foreseeable sources.

Who Created OHSAS? 

OHSAS 18001 was created via a concerted effort from a number of the worlds leading national standards bodies, certification bodies, and specialist consultancies. A main driver for this was to try to remove confusion in the workplace from the proliferation of certifiable OH&S specifications.

* South African Bureau of Standards

* British Standards Institution

* Bureau Veritas Quality International

* Det Norske Veritas

* Lloyds Register Quality Assurance

* National Quality Assurance

* SFS Certification

* SGS Yarsley International Certification Services

Occupational Health and Safety

 

Occupational safety and health (OSH) also commonly referred to as occupational health and safety (OHS) or workplace health and safety (WHS) is an area concerned with protecting the safety, health and welfare of people engaged in work or employment. The goals of occupational safety and health programs include to foster a safe and healthy work environment. OSH may also protect co-workers, family members, employers, customers, and many others who might be affected by the workplace environment. In the United States the term occupational health and safety is referred to as occupational health and occupational and non-occupational safety and includes safety for activities outside of work.

Occupational safety and health can be important for moral, legal, and financial reasons. All organisations have a duty of care to ensure that employees and any other person who may be affected by the companies undertaking remain safe at all times. Moral obligations would involve the protection of employee's lives and health. Legal reasons for OSH practices relate to the preventative, punitive and compensatory effects of laws that protect worker's safety and health. OSH can also reduce employee injury and illness related costs, including medical care, sick leave and disability benefit costs.

Since 1950, the International Labour Organization (ILO) and the World Health Organization (WHO) have shared a common definition of occupational health. It was adopted by the Joint ILO/WHO Committee on Occupational Health at its first session in 1950 and revised at its twelfth session in 1995. The definition reads:

"Occupational health should aim at: the promotion and maintenance of the highest degree of physical, mental and social well-being of workers in all occupations; the prevention amongst workers of departures from health caused by their working conditions; the protection of workers in their employment from risks resulting from factors adverse to health; the placing and maintenance of the worker in an occupational environment adapted to his physiological and psychological capabilities; and, to summarize, the adaptation of work to man and of each man to his job.

"The main focus in occupational health is on three different objectives: (i) the maintenance and promotion of workers’ health and working capacity; (ii) the improvement of working environment and work to become conducive to safety and health and (iii) development of work organizations and working cultures in a direction which supports health and safety at work and in doing so also promotes a positive social climate and smooth operation and may enhance productivity of the undertakings. The concept of working culture is intended in this context to mean a reflection of the essential value systems adopted by the undertaking concerned. Such a culture is reflected in practice in the managerial systems, personnel policy, principles for participation, training policies and quality management of the undertaking."

Workplace hazards

Although work provides many economic and other benefits, a wide array of workplace hazards also present risks to the health and safety of people at work. These include but are not limited to, "chemicals, biological agents, physical factors, adverse ergonomic conditions, allergens, a complex network of safety risks," and a broad range of psychosocial risk factors.

Physical and mechanical hazards

At-risk workers without appropriate safety equipment

Physical hazards are a common source of injuries in many industries. They are perhaps unavoidable in many industries such as construction and mining, but over time people have developed safety methods and procedures to manage the risks of physical danger in the workplace. Employment of children may pose special problems.

Falls are a common cause of occupational injuries and fatalities, especially in construction, extraction, transportation, healthcare, and building cleaning and maintenance.

An engineering workshop specialising in the fabrication and welding of components has to follow the Personal Protective Equipment (PPE) at work regulations 1992. It is an employers duty to provide ‘all equipment (including clothing affording protection against the weather) which is intended to be worn or held by a person at work which him against one or more risks to his health and safety’. In a fabrication and welding workshop an employer would be required to provide face and eye protection, safety footwear, overalls and other necessary PPE.

Machines are commonplace in many industries, including manufacturing, mining, construction and agriculture, and can be dangerous to workers. Many machines involve moving parts, sharp edges, hot surfaces and other hazards with the potential to crush, burn, cut, shear, stab or otherwise strike or wound workers if used unsafely. Various safety measures exist to minimize these hazards, including lockout-tagout procedures for machine maintenance and roll over protection systems for vehicles. According to the United States Bureau of Labor Statistics, machine-related injuries were responsible for 64,170 cases that required days away from work in 2008. More than a quarter of these cases required more than 31 days spent away from work. That same year, machines were the primary or secondary source of over 600 work-related fatalities. Machines are also often involved indirectly in worker deaths and injuries, such as in cases in which a worker slips and falls, possibly upon a sharp or pointed object. The transportation sector bears many risks for the health of commercial drivers, too, for example from vibration, long periods of sitting, work stress and exhaustion. These problems occur in Europe but in other parts of the world the situation is even worse. More drivers die in accidents due to security defects in vehicles. Long waiting times at borders cause that drivers are away from home and family much longer and even increase the risk of HIV infections.

Confined spaces also present a work hazard. The National Institute of Occupational Safety and Health defines "confined space" as having limited openings for entry and exit and unfavorable natural ventilation, and which is not intended for continuous employee occupancy. Spaces of this kind can include storage tanks, ship compartments, sewers, and pipelines. Confined spaces can pose a hazard not just to workers, but also to people who try to rescue them.

Noise also presents a fairly common workplace hazard: occupational hearing loss is the most common work-related injury in the United States, with 22 million workers exposed to hazardous noise levels at work and an estimated $242 million spent annually on worker's compensation for hearing loss disability. Noise is not the only source of occupational hearing loss; exposure to chemicals such as aromatic solvents and metals including lead, arsenic, and mercury can also cause hearing loss.

Temperature extremes can also pose a danger to workers. Heat stress can cause heat stroke, exhaustion, cramps, and rashes. Heat can also fog up safety glasses or cause sweaty palms or dizziness, all of which increase the risk of other injuries. Workers near hot surfaces or steam also are at risk for burns.  Dehydration may also result from overexposure to heat. Cold stress also poses a danger to many workers. Overexposure to cold conditions or extreme cold can lead to hypothermia, frostbite, trench foot, or chilblains.

Electricity poses a danger to many workers. Electrical injuries can be divided into four types: fatal electrocution, electric shock, burns, and falls caused by contact with electric energy.

Vibrating machinery, lighting, and air pressure can also cause work-related illness and injury. Asphyxiation is another potential work hazard in certain situations. Musculoskeletal disorders are avoided by the employment of good ergonomic design and the reduction of repeated strenuous movements or lifts.

Psychosocial hazards

Employers in most OECD countries have an obligation not only to protect the physical health of their employees but also the psychological health. Therefore as part of a risk management framework psychological or psychosocial hazards (risk factors) need to be identified and controlled for in the workplace. Psychosocial hazards are related to the way work is designed, organised and managed, as well as the economic and social contexts of work and are associated with psychiatric, psychological and/or physical injury or illness. Linked to psychosocial risks are issues such as occupational stress and workplace violence which are recognized internationally as major challenges to occupational health and safety.

Specific occupational safety and health risk factors vary depending on the specific sector and industry. Construction workers might be particularly at risk of falls, for instance, whereas fishermen might be particularly at risk of drowning. The United States Bureau of Labor Statistics identifies the fishing, aviation, lumber, metalworking, agriculture, mining and transportation industries as among some of the more dangerous for workers. Similarly psychosocial risks such as workplace violence are more pronounced in certain occupational groups such as health care employees, correctional officers and teachers.

Construction

Construction is one of the most dangerous occupations in the world, incurring more occupational fatalities than any other sector in both the United States and in the European Union. In 2009, the fatal occupational injury rate among construction workers in the United States was nearly three times that for all workers. Falls are one of the most common causes of fatal and non-fatal injuries among construction workers. Proper safety equipment such as harnesses and guardrails and procedures such as securing ladders and inspecting scaffolding can curtail the risk of occupational injuries in the construction industry. Due to the fact that accidents may have disastrous consequences for employees as well as organizations, it is of utmost importance to ensure health and safety of workers and compliance with HSE construction requirements. Health and safety legislation in the construction industry involves many rules and regulations. For example, the role of the Construction Design Management (CDM) Coordinator as a requirement has been aimed at improving health and safety on-site.

The 2010 National Health Interview Survey Occupational Health Supplement (NHIS-OHS) identified work organization factors and occupational psychosocial and chemical/physical exposures which may increase some health risks. Among all U.S. workers in the construction sector, 44% had non-standard work arrangements (were not regular permanent employees) compared to 19% of all U.S. workers, 15% had temporary employment compared to 7% of all U.S. workers, and 55% experienced job insecurity compared to 32% of all U.S. workers. Prevalence rates for exposure to physical/chemical hazards were especially high for the construction sector. Among nonsmoking workers, 24% of construction workers were exposed to secondhand smoke while only 10% of all U.S. workers were exposed. Other physical/chemical hazards with high prevalence rates in the construction industry were frequently working outdoors (73%) and frequent exposure to vapors, gas, dust, or fumes (51%).

Service sector

As the number of service sector jobs has risen in developed countries, more and more jobs have become sedentary, presenting a different array of health problems than those associated with manufacturing and the primary sector. Contemporary problems such as the growing rate of obesity and issues relating to occupational stress, workplace bullying, and overwork in many countries have further complicated the interaction between work and health.

According to data from the 2010 NHIS-OHS, hazardous physical/chemical exposures in the service sector were lower than national averages. On the other hand, potentially harmful work organization characteristics and psychosocial workplace exposures were relatively common in this sector. Among all workers in the service industry, 30% experienced job insecurity in 2010, 27% worked non-standard shifts (not a regular day shift), 21% had non-standard work arrangements (were not regular permanent employees).

Mining and oil & gas extraction

According to data from the 2010 NHIS-OHS, workers employed in mining and oil & gas extraction industries had high prevalence rates of exposure to potentially harmful work organization characteristics and hazardous chemicals. Many of these workers worked long hours: 50% worked more than 48 hours a week and 25% worked more than 60 hours a week in 2010. Additionally, 42% worked non-standard shifts (not a regular day shift). These workers also had high prevalence of exposure to physical/chemical hazards. In 2010, 39% had frequent skin contact with chemicals. Among nonsmoking workers, 28% of those in mining and oil and gas extraction industries had frequent exposure to secondhand smoke at work. About two-thirds were frequently exposed to vapors, gas, dust, or fumes at work.

The ILO management system was created to assist employers to keep pace with rapidly shifting and competitive industrial environments. The ILO recognizes that national legislation is essential, but sometimes insufficient on its own to address the challenges faced by industry, and therefore elected to ensure free and open distribution of administrative tools in the form of occupational health and safety management system guidance for everyone. This open access forum is intended to provide the tools for industry to create safe and healthy working environments and foster positive safety cultures within the organizations.

OHSAS 18000 is an international occupational health and safety management system specification developed by the London-based BSI Group, a multinational business chiefly concerned with the production and distribution of standards related services. OHSAS 18000 comprises two parts, OHSAS 18001 and 18002 and embraces a number of other publications. OHSAS 18000 is the internationally recognized assessment specification for occupational health and safety management systems. It was developed by a selection of leading trade bodies, international standards and certification bodies to address a gap where no third-party certifiable international standard exists. This internationally recognized specification for occupational health and safety management system operates on the basis of policy, planning, implementation and operation, checking and corrective action, management review, and continual improvement.

The British Standards – Occupational Health and Safety management Systems Requirements Standard BS OHSAS 18001 was developed within the framework of the ISO standards series. Allowing it to integrate better into the larger system of ISO certifications. ISO 9001 Quality Management Systems and ISO 14001 Environmental Management System can work in tandem with BS OHSAS 18001/18002 to complement each other and form a better overall system. Each component of the system is specific, auditable, and accreditable by a third party after review.

Professional roles and responsibilities

The roles and responsibilities of OSH professionals vary regionally, but may include evaluating working environments, developing, endorsing and encouraging measures that might prevent injuries and illnesses, providing OSH information to employers, employees, and the public, providing medical examinations, and assessing the success of worker health programs.

Identifying safety and health hazards

Hazards, risks, outcomes

The terminology used in OSH varies between countries, but generally speaking:

A hazard is something that can cause harm if not controlled.

The outcome is the harm that results from an uncontrolled hazard.

A risk is a combination of the probability that a particular outcome will occur and the severity of the harm involved. “Hazard”, “risk”, and “outcome” are used in other fields to describe e.g. environmental damage, or damage to equipment. However, in the context of OSH, “harm” generally describes the direct or indirect degradation, temporary or permanent, of the physical, mental, or social well-being of workers. For example, repetitively carrying out manual handling of heavy objects is a hazard. The outcome could be a musculoskeletal disorder (MSD) or an acute back or joint injury. The risk can be expressed numerically (e.g. a 0.5 or 50/50 chance of the outcome occurring during a year), in relative terms (e.g. "high/medium/low"), or with a multi-dimensional classification scheme (e.g. situation-specific risks).

Hazard identification

Hazard identification or assessment is an important step in the overall risk assessment and risk management process. It is where individual work hazards are identified, assessed and controlled/eliminated as close to source (location of the hazard) as reasonable and possible. As technology, resources, social expectation or regulatory requirements change, hazard analysis focuses controls more closely toward the source of the hazard. Thus hazard control is a dynamic program of prevention. Hazard-based programs also have the advantage of not assigning or implying there are "acceptable risks" in the workplace. A hazard-based program may not be able to eliminate all risks, but neither does it accept "satisfactory" – but still risky – outcomes. And as those who calculate and manage the risk are usually managers while those exposed to the risks are a different group, workers, a hazard-based approach can by-pass conflict inherent in a risk-based approach.

Risk assessment

Modern occupational safety and health legislation usually demands that a risk assessment be carried out prior to making an intervention. It should be kept in mind that risk management requires risk to be managed to a level which is as low as is reasonably practical.

This assessment should:

Identify the hazards

Identify all affected by the hazard and how

Evaluate the risk

Identify and prioritize appropriate control measures

The calculation of risk is based on the likelihood or probability of the harm being realized and the severity of the consequences. This can be expressed mathematically as a quantitative assessment (by assigning low, medium and high likelihood and severity with integers and multiplying them to obtain a risk factor), or qualitatively as a description of the circumstances by which the harm could arise.

The assessment should be recorded and reviewed periodically and whenever there is a significant change to work practices. The assessment should include practical recommendations to control the risk. Once recommended controls are implemented, the risk should be re-calculated to determine of it has been lowered to an acceptable level. Generally speaking, newly introduced controls should lower risk by one level, i.e., from high to medium or from medium to low.

Confined Space

A confined space is a place which is substantially enclosed (though not always entirely), and where serious injury can occur from hazardous substances or conditions within the space or nearby (e.g. lack of oxygen).
