The next step in a job safety analysis is to determine ways to eliminate the hazards or control the risks identified. Hazards should be controlled using the hierarchy of controls. The hierarchy of controls is a step-by-step approach to eliminating or reducing workplace hazards. For more information, please see the OSH Answers on Hierarchy of Controls. Following the same principles as the hierarchy of controls, you would implement preventive measures in the following order of preference: ## 1. Eliminate the hazard Elimination is the most effective measure. These techniques should be used to eliminate the hazards: - Choose a different process - Modify an existing process - Substitute with less hazardous product - Improve environment (e.g., ventilation) - Modify or change equipment or tools In the hierarchy of controls, these would be elimination or substitution controls. 2. Contain the hazard Job Safety Analysis CCOHS

# What are the benefits of doing a job safety analysis? (cont.) ## Who should conduct a job safety analysis? (cont.) The basic steps in conducting a job safety analysis are: - Select the job to be analyzed - Break the job down into a sequence of steps - Identify potential hazards - Determine preventive measures to control these hazards - Communicate the results ## What is important to know when "selecting the job"? Ideally, all jobs should be subjected to a job safety analysis. In some cases, practical constraints are posed by the amount of time and effort required to do a job safety analysis. Another consideration is that each job safety analysis will require revision whenever equipment, raw materials, processes, or the environment changes. For these reasons, it is usually necessary to identify which jobs are to be analyzed. Even if an analysis of all jobs is planned, this step ensures that the most critical jobs are examined first. Factors to be considered in setting a priority for the analysis of jobs include: - Incident frequency and severity: jobs where incidents occur frequently or where they occur infrequently but result in serious injuries. - Potential for severe injuries or illnesses: the consequences of an incident, hazardous condition, or exposure to harmful products are potentially severe. - Newly established jobs: due to lack of experience in these jobs, hazards may not be evident or anticipated. - Modified jobs: new hazards may be associated with changes in job procedures. - Infrequently performed jobs: workers may be at greater risk when undertaking non- routine jobs, and a JSA provides a means of reviewing hazards. ## How do I break the job into "basic steps"? After a job has been chosen for analysis, the next stage is to break the job into steps. A job step is defined as a segment of the operation necessary to advance the work. Job Safety Analysis CCOHS

# How do I "identify potential hazards"? (cont.) ## 1. Eliminate the hazard (cont.) If the hazard cannot be eliminated, contact might be prevented by using enclosures, machine guards, worker booths or similar devices. These are generally engineering controls. ## 3. Revise work procedures Consideration might be given to modifying steps which are hazardous, changing the sequence of steps, or adding additional steps (such as locking out energy sources). Work procedures and training fall under administrative controls. ## 4. Reduce the exposure These measures are the least effective and should only be used if no other solutions are possible. One way of minimizing exposure is to reduce the number of times the hazard is encountered. An example would be modifying machinery so that less maintenance is necessary. The use of appropriate personal protective equipment may be required. To reduce the severity of an incident, emergency facilities, such as eyewash stations, may need to be provided. This preventive measure is also an administrative control. Reducing the exposure may include using personal protective equipment. It is important to note that personal protective equipment can limit exposure to the harmful effects of a hazard, but only if the personal protective equipment is worn and used correctly. In listing the preventive measures, do not use general statements such as "be careful" or "use caution." Specific statements which describe both what action is to be taken and how it is to be performed are preferable. The recommended measures are listed in the right-hand column of the worksheet, numbered to match the hazard in question. For example: Job Safety Analysis CCOHS

# How do I "identify potential hazards"? Once the basic steps have been recorded, actual and potential hazards must be identified at each step. Based on observations of the job, knowledge of incident and injury causes, and personal experience, list the things that could be unsafe at each step. A second observation of the job being performed may be needed. Since the basic steps have already been recorded, more attention can now be focused on each hazard. At this stage, no attempt is made to solve any problems or correct any hazards which may have been detected. To help identify potential hazards, the job analyst may use questions such as these (this is not a complete list): - Can any body part get caught in or between objects? - Do tools, machines, or equipment present any hazards? - Can the worker make harmful contact with moving objects? - Can the worker slip, trip, or fall? - Can the worker suffer strain from lifting, pushing, or pulling? - Is the worker exposed to extreme heat or cold? - Is excessive noise or vibration a problem? - Is there a danger from falling objects? - Is lighting a problem? - Can weather conditions affect safety? - Is harmful radiation a possibility? - Can contact be made with hot, toxic, or caustic products? - Are there dusts, fumes, mists, or vapours in the air? Potential hazards are listed in the middle column of the worksheet, numbered to match the corresponding job step. For example: Job Safety Analysis CCOHS
