Carbon Dioxide Fire Extinguishers
Hercules carbon dioxide fire extinguishers singapore displace oxygen in order to put out fires. Upon discharge, the carbon dioxide is also very cold which is very useful in cooling, class B flammable liquid fires.
Carbon Dioxide does not leave a residue upon discharge. This makes it, by Singapore Standards 578’s definition, a clean agent. Carbon Dioxide fire extinguishers do not make a mess of the place or corrode, making them very useful in clean room, server room environments or as training equipment for fire fighters.
What type of fire can I use this fire extinguisher for?
Meticulously tested in laboratories, the Hercules fire extinguisher is capable of eliminating:
Class B fires which are flammable liquids such as paint, thinner, petrol, etc.
Class E fires which are electrical fires.*
*A key point to note is that SCDF is educating the public on NOT to directly using fire extinguishers on class E fires. E fires will reignite almost immediately as heat is still being generated. This is why the first step of eliminating a Class E fire is to turn off the source by shutting off the gas or electrical supply. If there is still a fire, the fire is likely to be a class A or B fire which will be much easier to put out as compared to a C or E fire. This is also why class E logos are no longer permitted on new fire extinguishers.
How to use a fire extinguisher?
Before you use a fire extinguisher, always ensure you have an escape route. If you have to use a fire extinguisher, do so at a safe distance. When in doubt, always choose to run. Even professional fire fighters in full fire resistant suits have been trained to never put their own lives at risk.
Always remember PASS. You can also read the instruction label on the fire extinguisher.
1. Pull the safety pin
2. Aim at the base of the fire
3. Squeeze the lever and sweep side to side.
How do I maintain a fire extinguisher?
According to the Singapore Fire Code, all non-personal use fire extinguishers must be maintained annually by a trained technician of a workshop registered with SCDF. You are able to make an appointment with Fire Armour to service your fire extinguishers.
Does this fire extinguisher expire?
Fire extinguishers do not expire like food. Every 10 years, carbon dioxide fire extinguishers are to undergo a full pressure test. In theory, if the fire extinguisher were to undergo a full pressure test every 10 years and assuming it has been kept in a reasonably clean environment, it can last indefinitely.
As SCDF requires all fire extinguishers to be maintained annually, a one year expiry sticker is affixed to every fire extinguisher that we sell. When the date has lapsed, it does not mean that the fire extinguisher has to be disposed. Instead, simply bring it to service your fire extinguishers and the expiry date can be extended. This rule does not affect fire extinguishers that are for personal use.
