Beyond Routine Checks When Fire Extinguishers Need Extra Testing

1. Beyond Routine Checks: When Fire Extinguishers Need Extra Testing Fire extinguishers are a vital part of any building's fire safety strategy. Regular testing, as outlined by Australian Standard AS1851, is crucial to ensure they function correctly during an emergency. While biannual testing is the norm, there are specific instances where additional testing is necessary to maintain their reliability and effectiveness. A fire extinguisher service Sydney describes the four critical scenarios that require extra attention: 1. In the Event of Cylinder Damage Cylinder damage is a serious concern for fire extinguishers. The cylinder is the core component that holds the pressurized extinguishing agent. Any damage to the cylinder, such as dents, cracks, or punctures, can compromise its integrity and lead to catastrophic failure during use. Damage can occur from accidental drops, impacts, or even during transport. When cylinder damage is suspected or observed, immediate testing is imperative. This involves a thorough inspection to assess the extent of the damage. Pressure tests are also conducted to ensure the cylinder can withstand the required pressure without leaking or bursting. If the cylinder fails these tests, it must be repaired or replaced to ensure safety and functionality.

2. 2. In Case of Significant Corrosion Corrosion is another threat to the integrity of fire extinguishers. It typically occurs when extinguishers are exposed to moisture or corrosive environments, such as industrial settings or coastal areas. Over time, corrosion can weaken the cylinder, leading to potential leaks or bursts. Significant corrosion is a red flag that warrants immediate testing. Visual inspections can identify surface rust and deeper pitting that may not be visible at first glance. Additionally, ultrasonic thickness testing can measure the cylinder walls' remaining thickness, ensuring they are still within safe limits. If corrosion has significantly compromised the extinguisher, it should be decommissioned and replaced. Search for “fire extinguisher service near me” online to get started. 3. In Case of a Fire in Their Vicinity Fire extinguishers that have been exposed to a fire, even if not directly used, should be subjected to extra testing. The heat from a nearby fire can affect the extinguisher's components, such as the pressure gauge, seals, and the cylinder itself. Heat exposure can cause these components to degrade or malfunction. Post-fire testing involves a comprehensive check of all extinguisher parts. The pressure gauge is examined to ensure it reads accurately, and seals are inspected for signs of melting or deformation. The cylinder should be checked for any signs of heat damage, which might include discoloration or warping. Extinguishers exposed to significant heat should be replaced to ensure reliability in future emergencies. 4. When the Extinguisher is Made from Steel and Filled with Calcium Chloride Extinguishing Agent Fire extinguishers made from steel and filled with calcium chloride as the extinguishing agent present a unique scenario. Calcium chloride is highly corrosive, especially when it interacts with steel. Over time, this can lead to internal corrosion that is not immediately visible from the outside.

3. For these extinguishers, extra testing involves both internal and external inspections. Internally, corrosion can be assessed using endoscopic cameras or by sampling the internal agent for signs of contamination. Externally, regular inspections should look for any signs of leakage or external rust. If internal corrosion is detected, the extinguisher must be replaced to prevent failure during use. Conclusion: By staying vigilant and proactive in these situations, building owners and managers can ensure that their fire extinguishers remain reliable and effective, safeguarding lives and property in the event of a fire. Regular maintenance and attention by fire extinguisher service companies near me are key to maintaining a robust fire safety strategy.
