¹ Each Job or Operation consists of a set of steps. Be sure to list all the steps in the sequence that they are performed. Specify the equipment or other details to set the
basis for the associated hazards in Column 2
² A hazard is a potential danger. What can go wrong? How can someone get hurt? Consider, but do not limit, the analysis to: Contact - victim is struck by or strikes an
object; Caught - victim is caught on, caught in or caught between objects; Fall - victim falls to ground or lower level (includes slips and trips); Exertion - excessive strain or stress /
ergonomics / lifting techniques; Exposure - inhalation/skin hazards. Specify the hazards and do not limit the description to a single word such as "Caught"
³ Aligning with the first two columns, describe what actions or procedures are necessary to eliminate or minimize the hazards. Be clear, concise and specific. Use
objective, observable and quantified terms. Avoid subjective general statements such as, "be careful" or "use as appropriate".
