Chemical Reactivity Hazards

Overview

Highlights
  • Ammonia Refrigeration. OSHA eTool. Assists employers and employees in identifying and controlling the hazards associated with the operation and maintenance of ammonia refrigeration systems. Many of the requirements of the Process Safety Management (PSM) Standard, 29 CFR 1910.119, are identified in this eTool as possible controls and are useful as recommended practices, whether or not the ammonia refrigeration system is a covered process.

Chemicals have the ability to react when exposed to other chemicals or certain physical conditions. The reactive properties of chemicals vary widely and they play a vital role in the production of many chemical, material, pharmaceutical, and food products we use daily. When chemical reactions are not properly managed, they can have harmful, or even catastrophic consequences, such as toxic fumes, fires, and explosions. These reactions may result in death and injury to people, damage to physical property, and severe effects on the environment. Process Safety Management is used to prevent and mitigate chemical reactivity hazards.
