Traditional extinguishers are not only ineffective but dangerous to use against metal fires. For metal fires, the class D fire extinguisher is used instead. Effective against lithium, sodium, magnesium ,calcium ,zinc and aluminium fires when in the form of powder or swarf.

To prevent splashing of the molten metal, these extinguishers are equipped with a low velocity applicator cup 1.5m in length. This provides a degree of safety to the person operating the extinguishers.

The unique lance applicator is designed to allow the powder to fall gently over the fire to prevent burning material from spreading.

ABS 12KG Class D fire extinguisher are used specifically for metal fires. Pressurized fire extinguishers such as powder or foam types will not only be able to put out class D fire but will cause the fire to splash and grow faster. The Class D fire extinguisher works by burying the fire. Powder slowly falls off the applicator with a cup end. The cup intentionally forces the powder to spread over a smaller surface area rather than a larger area. This burial cuts off the oxygen from the fire and effectively stops it.

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.

This fire extinguisher does not use the usual PASS method. Operators in the hazard area have to be informed on how to use this fire extinguisher. The aim is to bury the fire in class D powder.

You can also read the instruction label on the fire extinguisher.

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 5 years, fire extinguishers are to undergo a full pressure test. In theory, if the fire extinguisher were to undergo a full pressure test every 5 years and assuming it has been kept in a reasonably clean environment, it can last indefinitely. However, this is rare in reality as it is simply more economical to purchase a new piece every 5 years.

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 us here to service your fire extinguishers and the expiry date can be extended. This rule does not affect fire extinguisher that are for personal use.
