# Fire Extinguisher Safety

## Build Essential Knowledge for Fire Prevention, Extinguisher Selection and Emergency Response

A fire can develop rapidly, turning a small incident into a serious emergency within a short period of time. Knowing how fires start, understanding fire classifications and recognising the correct type of fire extinguisher can help people respond more appropriately when an emergency occurs.

**Fire Extinguisher Safety** provides learners with foundational knowledge about fire behaviour, portable fire extinguishers, extinguisher selection, safe operating techniques and basic maintenance. The course explores the fire triangle, fire classifications, how extinguishers work, the PASS technique, practical extinguisher use, maintenance requirements and specific considerations for confined spaces and flammable liquid fires.

The course is designed to help learners develop awareness and confidence around fire extinguishers while emphasising an essential principle: **personal safety and evacuation always come first**. A fire extinguisher should only be used when the fire is small and appropriate to tackle, the correct extinguisher is available, an escape route is accessible and the person using it has been trained and is able to act safely.

> **Important:** This course provides general educational information and does not replace site-specific fire training, local fire regulations, emergency procedures or practical training delivered by a qualified fire-safety professional. In a fire emergency, follow your workplace or building’s evacuation procedure and contact the appropriate emergency services. Never attempt to fight a fire if doing so would put you or others at risk.
