Chemical Reactivity Hazards
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.
Chemical reactivity hazards are addressed in specific OSHA standards for general industry and construction.
Provides references that aid in recognizing chemical reactivity hazards.
Provides information that may aid in evaluating reactive interactions and their potential hazards.
Control and Prevention
Provides information about the control and prevention of chemical reactivity hazards, including laboratory safeguards.
Provides links and references to additional resources related to chemical reactivity hazards.
- 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.
Workers have the right to:
- Working conditions that do not pose a risk of serious harm.
- Receive information and training (in a language and vocabulary the worker understands) about workplace hazards, methods to prevent them, and the OSHA standards that apply to their workplace.
- Review records of work-related injuries and illnesses.
- File a complaint asking OSHA to inspect their workplace if they believe there is a serious hazard or that their employer is not following OSHA's rules. OSHA will keep all identities confidential.
- Exercise their rights under the law without retaliation, including reporting an injury or raising health and safety concerns with their employer or OSHA. If a worker has been retaliated against for using their rights, they must file a complaint with OSHA as soon as possible, but no later than 30 days.

How to Contact OSHA
Under the Occupational Safety and Health Act of 1970, employers are responsible for providing safe and healthful workplaces for their employees. OSHA's role is to help ensure these conditions for America's working men and women by setting and enforcing standards, and providing training, education and assistance.
