Process Safety A discipline that focuses on the prevention and mitigation of fires, explosions, and accidental chemical releases at process facilities. Excludes classic worker health and safety issues involving working surfaces, ladders, protective equipment, etc. 

Guidelines for Post Release Mitigation in the Chemical Process Industry (1997)... 

When considering the potential for ecological impacts, understanding exposure is vital. Without exposure (whether release to the environment is intentional or not), there is no risk to ecosystems, regardless of the toxicity of the chemical. Therefore, mitigating possible exposure to toxic compounds, whether through chemical design... 

Safety engineers and experts are now being asked to conduct the risk assessments required to understand the impact of component and structural failures, uncontrolled radiation or chemical releases, transient operations and unanticipated shutdowns occurring at the chemical or nuclear plant on the safe operation of the other plant. Based on these assessments, control systems and mitigation actions are being developed to minimise the impact of a component or structure failures. Finally,... 

This section describes four additional techniques for mitigating releases of hazardous substances into the atmosphere. In addition to water, both steam and compressed air can be used to promote the movement of air to dilute a hazardous material. Foam can be used as a scrubbing medium to entrap a hazardous material in its structure. Foam scrubbing is often effective for materials that are soluble in water, or that are highly reactive with an additive contained in the foam. Lastly, dry powders can be used to capture a reactive chemical released into the air. 

These standards also target highly hazardous chemicals and radioactive substances that have the potential to cause catastrophic incidents. This standard as a whole is to help employees in their efforts to prevent or mitigate the episodic chemical releases that could lead to a catastrophe in the workplace, and the possibility of the surrovmding community to control these types of hazards. Employers must develop the necessary expertise, experience, judgment, and proactive initiative within their workforce to properly implement and maintain an... 

PSM is the proactive identification, evaluation, and mitigation or prevention of chemical releases that could occur as a result of failures in processes, procedures, or equipment. Appendix C referred to above covers 14 topics ... 

Physical protection measures that are in place to mitigate the harm that could result from a chemical release or spill. 

The Chemical Transportation Emergency Center (CHEiMTREQ was established as a public service by the American Chemistry Council (ACC) in 1971. It was organized in response to several accidental chemical releases for which responders could not obtain adequate information to mitigate the hazards. ACC s approximately 190 member companies represent more than 90% of the productive capacity for basic industrial chemicals in the United States.
