How frequently are fire extinguisher containers checked for pressure limits?

Fire extinguisher containers are checked for pressure limits periodically to ensure they are in functional condition and ready for use in case of a fire emergency. This periodic checking is vital because it allows for the identification of any issues with the pressure that could affect the extinguisher’s effectiveness. Regular assessments help maintain safety standards and compliance with regulations, ensuring that the extinguishers are always prepared and reliable when needed.

The periodic checks should involve inspecting the pressure gauge to confirm that it is within the designated safe range. Additionally, visual inspections might include checking for physical damage, corrosion, and ensuring the pin and tamper seal are intact. This practice minimizes the risk of malfunction in emergency situations.

In contrast, checking monthly or yearly may not provide enough flexibility for addressing issues as they arise, and only checking after use does not ensure the extinguishers are in proper working condition before a fire incident occurs.
