How frequently should a fire extinguisher be pressure tested?

Fire extinguishers require periodic pressure testing to ensure they remain functioning safely and effectively. The standard practice for pressure testing is typically every 5 to 6 years for most types of portable fire extinguishers. This interval helps ensure that the internal pressure is adequate and that no leaks or other issues have developed that could compromise the extinguisher's performance during an emergency.

Pressure testing every 5 to 6 years aligns with NFPA (National Fire Protection Association) guidelines, which recommend this timeline for routine maintenance of extinguishers to ensure they are reliable and can be properly discharged when needed. Regular inspections and maintenance are vital parts of fire safety protocols, yet pressure testing specifically serves to assess the integrity of the pressurized components of the extinguishers over time.

Understanding the correct frequency of pressure testing assists in maintaining safety standards in various environments, such as homes, businesses, and industrial settings.
