Selection of Hazard Evaluation Techniques

However, all of these efforts depend on a successful hazard evaluation program; without these evaluations, the company will not know what layers of protection are needed.

A successful hazard evaluation program requires tangible management support; sufficient, technically competent people (some of whom must be trained to use hazard evaluation techniques); adequate, up-todate information and drawings; and selection of the techniques (matched to the complexity and hazard of the process). Fortunately, a variety of flexible hazard evaluation techniques exist. Below is a simple listing of generally accepted techniques:
1
Qualitative Techniques: These methods help a multi-disciplinary team (1) identify potential accident scenarios and (2) evaluate the scenario in sufficient detail to make a reasonable judgment of risk. If the team is confused on the risk, a scenario identified in a... [continues]
