Acceptable Risk The average rate of loss that is considered tolerable for a given activity. Accident An unplanned event or sequence of events that results in an undesirable consequence. An occurrence where property damage, material loss, detrimental environmental impact or human injury occurs. Accidental Release An unanticipated emission of a regulated substance or other extremely hazardous substance into the ambient air. Action Items A column in the What-If/Checklist Worksheet that serves to record any proposed risk-reduction measures that result from a PHA. Action Items include design, operating, or maintenance changes that reduce or eliminate hazards and/or consequences. Action Items identified in a hazard analysis study are preliminary in nature. Requests for additional information or study can also made as What-If/Checklist Action Items. It is common to also refer to these items as recommendations. Active Mitigation Active mitigation is defined as equipment, devices, or technologies that need human, mechanical, or other energy input to function. An example is an interlock which needs an ammonia detector in order to function. Actuator A mechanism that transmits movement to a component of a device such as the stem of a valve. Administrative Controls Work procedures such as written safety policies, rules, supervision, schedules, and training with the goal of reducing the duration, frequency, and severity of exposure to hazardous chemicals or situations. Administrative Controls are procedural mechanisms for controlling, monitoring, or auditing human performance. An example would be written procedures designed to limit the maximum quantity of ammonia in a vessel to 80% of the vessel's total capacity. Affected Employee Any employee who works within the vicinity of an ammonia refrigeration system but who is strictly prohibited from affecting the performance and safety of the system. These employees are not allowed to perform any adjustments, troubleshooting, emergency action or response, or maintenance to the ammonia refrigeration system.
