A Risk Determining Model for Hazardous Material Operations: Part II

Conference paper


Safe work practices are an essential part of Integrated Safety Management (ISM) and apply to issues of environment, safety, and health. Safe work practices require defining the work; establishing, documenting, and maintaining an effective hazard-control system within which the work is performed; and authorizing both the defined work and the workers to perform the work [1]. Integrating safe work practices with work activities requires workers and their line managers/supervisors to use a systematic, tailored approach and good judgment in applying their knowledge of the work to identifying hazards and controls so that the work can be performed safely. Nowhere is the need for good judgment more apparent than when a line manager/ supervisor is called upon to evaluate the initial and residual risks associated with the work. If a line manager/supervisor underestimates the initial risk associated with an activity, certain required levels of independent peer and/or Environmental, Health & Safety (ES&H) subject matter expert reviews are not performed. If a line manager/ supervisor overestimates the initial risk, unnecessary expense and delays are encountered. Similar issues develop when the residual risk is misjudged. Underestimating the residual risk could result in hazardous material operations that pose an unacceptable risk being conducted. Overestimating the residual risk leads to work slowdowns caused by excessive periodical reviews of operations and overtraining.
