More than 80 years ago, UL developed the test standards for fire extinguishers that still guide the product development process today. As new technologies emerge, UL’s team of engineers continue to work with our customers to address emerging safety and performance challenges.

UL offers certification to all key standards pertaining to fire extinguishers, specifically the UL and CAN/ULC Standards for carbon dioxide, dry chemical, foam, halocarbon clean agent, and water-type fire extinguishers. In the United States and Canada, extinguishers are intended to be selected, installed, inspected, maintained and tested in accordance with NFPA 10, standard for Portable Fire Extinguishers.

Fire extinguishers that comply with Brazil’s Portaria 486 and ABNT NBR 15808 are eligible to use the Brazilian-recognized conformity mark, INMETRO Mark, in conjunction with the UL Mark for Brazil.

The UL Mark on a fire extinguisher, as well as on fire extinguisher components and agents, is widely recognized to indicate that they meet the standards for safety and performance.
