Hydrostatic Testing Requirements for Portable Fire Extinguisher Cylinders 

July 26, 2019 Roy Williams

Federal laws (and in some cases state and municipal statutes) require that most of the pressure cylinders associated with portable fire extinguishers must be periodically hydrostatically retested to ensure their safety. In addition, the laws require hydrostatic testing of cylinders which show evidence of corrosion or mechanical injury.

Principal authorities

The two principal authorities that have jurisdiction over portable fire extinguisher cylinders are the National Fire Protection Association (NFPA) and the Code of Federal Regulations, (DOT, OSHA and MSHA).

National Fire Protection Association (NFPA) hydrostatic testing requirements

NFPA standards have no force of law in and of themselves unless adopted by a regulatory entity that is empowered by statute to enforce regulations. However, as consensus standards developed by teams of recognized experts, they represent sound fire safety principles, practices and procedures. Moreover, some states and municipalities have adopted NFPA standards as a part of their fire protection codes, including those parts dealing with the maintenance and hydrostatic retesting of extinguishers. 

Department of Transportation (DOT) hydrostatic testing requirements

DOT hydrostatic retest requirements apply only to charged pressure cylinders which are transported in commerce in the U.S. or to foreign countries. Once the product reaches its original destination, DOT rules apply only when the container is reshipped in a charged condition or being refilled. 

Occupational Safety and Health Administration (OSHA) hydrostatic testing requirements

OSHA has safety jurisdiction over most workplaces in the U.S., and as such its regulations have the force of federal law. OSHA has not adopted NFPA standards for hydro-testing per se, but its requirements follow NFPA standards closely. 

Mine Safety and Health Administration (MSHA) hydrostatic testing requirements

MSHA has safety jurisdiction over mines and generally references the appropriate NFPA and DOT regulations for additional guidelines on extinguisher hydrostatic testing. 

Hydrostatic testing should only be performed by trained, qualified persons
