How frequently are portable fire extinguishers required to be inspected?

Portable fire extinguishers are required to be inspected monthly to ensure they are in proper working condition. This inspection is crucial because it allows personnel to check for any signs of damage, verify that the extinguishers are properly mounted and accessible, and ensure that they are fully charged. Regular monthly inspections help identify issues early, providing an opportunity to maintain firefighting equipment and ensure safety in the lab or workplace environment. While other time frames such as weekly or quarterly inspections might increase safety, the established monthly standard is sufficient to maintain compliance and operational readiness.
