# Hazard and Risk - Hazard Control (cont.) ## What is a hazard control program? (cont.) For example, in the case of a noise hazard, temporary measures might require workers to use hearing protection. Long-term, permanent controls might use engineering methods to remove or isolate the noise source. ## Why should a workplace implement hazard controls? In all cases, the employer has a duty of due diligence and is responsible for 'taking all reasonable precautions, under the particular circumstances, to prevent injuries or incidents in the workplace'. Some hazards and their controls will be specifically outlined in legislation. In situations where there is not a clear way to control a hazard, or if legislation does not impose a limit or guideline, you should seek guidance from occupational health professionals such as an occupational hygienist, ergonomist, engineer, or safety professional about what is the "best practice" or "standard practice" when working in that situation. Unsafe Safe There is NOT a fine line between Safe and Unsafe Figure 1 ## Remember! A legal limit or guideline (such as an occupational exposure limit) should never be viewed as a line between "safe" and "unsafe". The best approach is to always keep exposures or the risk of a hazard as low as possible. ## What are the main ways to control a hazard? The main ways to control a hazard include: - Elimination: remove the hazard from the workplace. - Substitution: replace the hazard (e.g., hazardous products, machines, etc.) with a less hazardous one. - Engineering Controls: includes designs or modifications to plants, equipment, ventilation systems, and processes that reduce the source of exposure.

# Hazard and Risk - Hazard Control (cont.) ## What are the main ways to control a hazard? (cont.) - Administrative Controls: controls that alter how the work is done, including timing of work, policies and other rules, and work practices such as standards and operating procedures (including training, housekeeping, equipment maintenance, and personal hygiene practices). - Personal Protective Equipment: equipment worn by individuals to reduce exposure, such as contact with chemicals or exposure to noise. These methods are also known as the "hierarchy of controls". For more information, please see the OSH Answers document Hierarchy of Controls. ## Where are controls used? Controls are usually placed: 1. At the source (where the hazard "comes from"). 2. Along the path (where the hazard "travels"). 3. At the worker. Air Path Dip Tank Source Worker Figure 2 The best strategy is to control the hazard at its source. Control at the source and control along the path are sometimes also known as engineering controls. ## Why is it important to monitor and review your hazard control program and methods? It is important to monitor both the hazard and the control method to make sure that the control is working effectively and that exposure to the hazard is reduced or eliminated. Some tools include physical inspection, testing, exposure assessment, observations, injury and illness tracking, incident investigations reports, employee feedback or input, occupational health assessment and other methods.

Why is risk assessment important? What is the goal of risk assessment? When should a risk assessment be done? How do you plan for a risk assessment? How is a risk assessment done? How are the hazards identified? How do you know if the hazard will cause harm (poses a risk)? How are risks ranked or prioritized? What risk assessment methods should be used? What are methods of hazard control? Why is it important to review and monitor the assessments? What documentation should be done for a risk assessment? ## What is a risk assessment? Risk assessment is a term used to describe the overall process or method where of identifying hazards, assessing the risk of hazards, and prioritizing hazards associated with a specific activity, task, or job. It considers the probability or likelihood of harm from exposure and the potential consequence or severity of harm from exposure to a hazard. A risk assessment is a thorough look at your workplace to identify those things, situations, processes, etc. that may cause harm, particularly to people. After the identification of a hazard, it should be reviewed to determine how likely and severe the potential harm is. When this determination is made, you can decide what measures should be in place to effectively eliminate or control the harm from happening (hazard control). Some important terms related to risk assessments include: Hazard - a potential source of injury, adverse health effect, or damage to people, structures, equipment, or the environment. A common way to classify hazards is to categorize them as biological, chemical, ergonomic, physical, psychosocial, and safety hazards. Hazard identification - the process of finding, listing, and characterizing hazards. Hazard and Risk - Risk Assessment CCOHS

# Hazard and Risk - Hazard Identification (cont.) ## What types of hazards are there? (cont.) - Biological - bacteria, viruses, fungi, insects, plants, and animals. - Chemical - depends on the physical, chemical, and toxic properties of the product - Ergonomic - repetitive movements, improper setup of workstations, etc. - Physical - radiation, magnetic fields, temperature extremes, pressure extremes (high pressure or vacuum), noise, vibration, etc. - Psychosocial - stress, violence, harassment, etc. - Safety. - slipping or tripping hazards, inappropriate machine guarding, equipment malfunctions or breakdowns. ## How do I know what is a hazard? Another way to look at health and safety in your workplace is to ask yourself the following questions. These are examples only. You may find other items or situations that can be a hazard. List any item that should be examined. During the risk assessment process, the level of harm will be assessed. What materials or situations do I come into contact with? Possibilities could include: - Electricity. - Chemicals (liquids, gases, solids, mists, vapours, etc.). - Temperature extremes of heat or cold (such as working outdoors, bakeries, foundries, or meat processing). - lonizing and non-ionizing radiation (such as x-rays, ultraviolet (sun) rays). - Asphyxiants (oxygen deficiency) - Working on or near water or ice-covered water. What materials or equipment could I be struck by? - Moving objects (such as forklifts, overhead cranes, vehicles). - Flying objects (such as sparks or shards from grinding). - Falling material (such as tools and equipment from above). What objects or equipment could strike or hit my body, or that part of my body might be caught in, on, or between? - Stationary or moving objects. - Protruding objects. - Sharp or jagged edges.

Where can I find more information about hazards? What if I am new to the task or the workplace? ## What is a hazard? There are many definitions of hazard, but the most common definition when talking about workplace health and safety is "A hazard is any source of potential damage or harm to someone or something." The CSA Z1002 Standard "Occupational health and safety - Hazard identification and elimination and risk assessment and control" uses the following terms: - Harm - physical injury or damage to health. - Hazard - a potential source of harm to a worker. Basically, a hazard is the potential for harm or an adverse effect (for example, to people as health effects, to organizations as property or equipment losses, or to the environment). Please see the OSH Answers fact sheet on Hazard and Risk for more information. ## What is hazard identification? Hazard identification is part of the process used to evaluate if any particular situation, item, or thing may have the potential to cause harm.
