A hazard is a condition, practice or behaviour (in the workplace) that has the potential to cause injury, illness or property damage. Having a process to recognize, evaluate and control these hazards is the key to a safe and healthy workplace. Controlling hazards results in fewer illnesses and injuries, reduces associated incident costs, increases productivity, improves morale and reinforces a company’s commitment to providing healthy and safe working conditions.
A job hazard analysis/job safety analysis (JHA/JSA) is just one tool to assist employers with hazard recognition, evaluation and control. A JHA takes a particular task, breaks it down into its basic steps and assesses the hazards at each step. It helps to ensure that workers understand how the work is to proceed as well as the task specific hazards and control measures necessary for their protection.
