Hazard

A process of examining a system throughout its life cycle to identify and eliminate or mitigate to an acceptable level inherent safety-related risks. HA provides a prioritized assessment of real or potential conditions that may cause harm or undesired damage, enabling a focus on eliminating or mitigating to an acceptable level the most severe and/or frequent hazards.

A technique used to determine the effectiveness of safeguards and safety-instrumented functions for providing risk reduction as protection from hazards identified for a given process. The identified hazards can be as a result of an earlier HAZOP.

All plans and actions taken to identify hazards; assess and mitigate associated risks; and track, control, accept, and document risks encountered in the design, development, test, acquisition, use, and disposal of systems, subsystems, equipment, and infrastructure.

Freedom from hazards when equipment is in proper operation or when operating a piece of equipment in a predictable but improper manner.

1) A hazard that could result in a mishap causing fatal injury to personnel and/or loss of one or more major elements of major assets or the facility. (2) A condition that may cause death or permanently disabling injury, major system or facility destruction on the ground, or loss of personnel, or major systems.
