A hazard is essentially a condition or activity that, if left uncontrolled, may result in an accident or a serious injury. To effectively identify hazards, the observer must develop a means of recognizing a hazard exposure. What I see repeatedly in the field are hazard lists like “wear PPE, stay out of the bite, watch for cars, cover up well.” What I don’t see is an effective approach to identifying hazards. I had occasion to investigate a 4-kV contact in a metal-clad breaker where the worker brushed his hand against a control power transformer that had not been identified or tested. For three days he had his head in the cabinet, unaware that the primary leads for the transformer had been moved from the load side to the high side of the breaker contacts. For three days his pre-job hazard analysis entries included “check for voltage.” He survived, but not because of his hazard analysis.
