Risk assessments are very important as they form an integral part of an occupational health and safety management plan. They help to:

• Create awareness of hazards and risk.
• Identify who may be at risk (e.g., employees, cleaners, visitors, contractors, the public, etc.).
• Determine whether a control program is required for a particular hazard.
• Determine if existing control measures are adequate or if more should be done.
• Prevent injuries or illnesses, especially when done at the design or planning stage.
• Prioritize hazards and control measures.
• Meet legal requirements where applicable.

When should a risk assessment be done?

There may be many reasons a risk assessment is needed, including:

• Before new processes or activities are introduced.
• Before changes are introduced to existing processes or activities, including when products, machinery, tools, equipment change or new information concerning harm becomes available.
• When hazards are identified.

How is a risk assessment done?

Assessments should be done by a competent person or team of individuals who have a good working knowledge of the situation being studied. Include either on the team or as sources of information, the supervisors and workers who work with the process under review as these individuals are the most familiar with the operation.

In general, to do an assessment, you should:

• Identify hazards.
• Determine the likelihood of harm, such as an injury or illness occurring, and its severity.
• Consider normal operational situations as well as non-standard events such as maintenance, shutdowns, power outages, emergencies, extreme weather, etc.
• Review all available health and safety information about the hazard such as Safety Data Sheet (SDS), manufacturers literature, information from reputable organizations, results of testing, workplace inspection reports, records of workplace incidents (accidents), including information about the type and frequency of the occurrence, illnesses, injuries, near misses, etc.
• Understand the minimum legislated requirements for your jurisdiction.
• Identify actions necessary to eliminate the hazard, or control the risk using the hierarchy of risk control methods.
• Evaluate to confirm if the hazard has been eliminated or if the risk is appropriately controlled.
• Monitor to make sure the control continues to be effective.
• Keep any documents or records that may be necessary. Documentation may include detailing the process used to assess the risk, outlining any evaluations, or detailing how conclusions were made.

When doing an assessment, also take into account:

• The methods and procedures used in the processing, use, handling or storage of the substance, etc.
• The actual and the potential exposure of workers (e.g., how many workers may be exposed, what that exposure is/will be, and how often they will be exposed).
• The measures and procedures necessary to control such exposure by means of engineering controls, work practices, and hygiene practices and facilities.
• The duration and frequency of the task (how long and how often a task is done).
• The location where the task is done.
• The machinery, tools, materials, etc. that are used in the operation and how they are used (e.g., the physical state of a chemical, or lifting heavy loads for a distance).
• Any possible interactions with other activities in the area and if the task could affect others (e.g., cleaners, visitors, etc.).
• The lifecycle of the product, process or service (e.g., design, construction, uses, decommissioning).
• The education and training the workers have received.
• How a person would react in a particular situation (e.g., what would be the most common reaction by a person if the machine failed or malfunctioned).

It is important to remember that the assessment must take into account not only the current state of the workplace but any potential situations as well.

By determining the level of risk associated with the hazard, the employer, and the health and safety committee (where appropriate), can decide whether a control program is required and to what level
