' Each Job or Operation consists of a set of tasks/steps. Be sure to list all the steps needed to perform job. ' A hazard is a potential danger. Break hazards into six types: 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;Energy Source-Electricity,pressure,tension/compression,torque. ' Using the first two columns as a guide,decide what actions or procedures are necessary to eliminate or minimize the risk. List the recommended safe operating procedures. Say exactly what needs to be done-such as"use two persons to lift". Avoid general statements such as,"be careful'. ROUX ASSOCIATES, INC.
