If you run a business in Singapore or even keep a fire extinguisher at home, one important question often comes up: how often does it need to be serviced?
Many people assume that as long as the pressure gauge is in the green zone, the extinguisher is fine. Unfortunately, that is not always the case. A fire extinguisher is a pressurised safety device, and like any safety equipment, it requires proper maintenance to ensure it works when needed.
In Singapore, commercial premises are required to ensure that fire extinguishers are properly maintained and ready for use at all times. The Singapore Civil Defence Force (SCDF) requires that fire safety equipment in regulated buildings be maintained in accordance with recognised standards. For most businesses, this means fire extinguishers must be serviced at least once every year.
Annual servicing is not just a quick visual check. A proper maintenance process includes examining the pressure level, inspecting the hose and nozzle, checking the safety pin and tamper seal, and ensuring the cylinder body has no corrosion, dents, or leaks. The technician will also confirm that the extinguisher is still suitable for the fire risks present in the premises.
Even if the extinguisher has not been used, internal components can deteriorate over time. Seals may weaken, pressure may slowly drop, and powder can compact inside the cylinder. Compacted powder can prevent proper discharge during a fire. This is why servicing is required even if the extinguisher appears untouched.
If a fire extinguisher has been discharged, even partially, it must be refilled and serviced immediately. The pressure inside the cylinder drops once it is activated, and it cannot be relied upon until properly refilled and tested.
In addition to annual servicing, fire extinguishers also have a longer-term lifespan. Over several years, depending on the type, they may require more thorough inspection or replacement. The metal cylinder itself must remain structurally sound because it contains compressed gas. Internal corrosion or weakening of the body can pose safety risks.
For businesses, keeping up with servicing is not only about safety but also compliance. During inspections, officers will check the servicing label to ensure it is within the valid period. An expired servicing tag may be considered non-compliant. More importantly, if a fire occurs and the extinguisher fails due to lack of maintenance, the consequences can be severe.
For homeowners in Singapore, regular servicing is strongly recommended even though routine inspections may not apply in the same way as commercial properties. Fires in residential units can spread quickly, especially in enclosed apartment environments. Ensuring your extinguisher is in working condition provides peace of mind for your family.
As a general guide in Singapore:
• Fire extinguishers in commercial premises should be serviced annually.
• Any discharged extinguisher should be serviced immediately.
• Units showing signs of damage, corrosion, or pressure loss should be assessed without delay.
Fire safety works on the principle of early intervention. A small fire can often be controlled in seconds with a properly functioning extinguisher. But if the extinguisher fails due to poor maintenance, that small fire can escalate rapidly.
Regular servicing is not just a regulatory requirement. It is a simple, preventive step that ensures your equipment performs when seconds matter most.
If you are unsure when your fire extinguisher was last serviced or whether it remains compliant in Singapore, it is always safer to check early rather than wait for an inspection or an emergency.
