In what order should you extinguish a fire?

The Theory of Extinguishing A Fire

1. Starving The Fire. Remove the fuel – i.e. the unburnt material. ...
2. Smothering The Fire. Prevent oxygen from combining with the fuel. ...
3. Cooling The Fire. Reduce the temperature of the burning material to below its ignition point. ...
4. Interrupting The Chemical Chain Reaction.

What is the new type of fire extinguisher?

What is the 30/30/30 rule for fire?

The 30-30-30 rule for fire is a guideline indicating extreme wildfire risk: when the temperature is 30°C (86°F) or higher, relative humidity is 30% or lower, and wind speeds are 30 km/h (19 mph) or higher, conditions are ripe for fast, hard-to-control fires that preheat fuels and spread embers rapidly, a state sometimes called "crossover". This rule helps forecasters and the public recognize dangerous fire weather, as seen in events like the 2016 Fort McMurray fire. 

What are the 4 P's of fire safety?

The 4 Ps of fire safety generally refer to Prevention, Protection, Preparedness, and Practice, a framework for stopping fires, having tools ready, knowing what to do, and regularly drilling procedures. Other versions might use different P-words like Process or focus on cold weather protection like People, Pets, Pipes, and Plants, but the core concepts of stopping fires and being ready remain consistent across these models, with Prevention (stopping fires), Protection (equipment), Preparedness (planning), and Practice (drills) being the most common.
 

What is the most common method of fire extinguishment?

Water – Pouring water on a fire is one of the most often used methods of putting it out. Heat energy is easily absorbed by water. Spraying water on flames with high temperatures successfully lowers the fire's temperature and vaporizes water.

What are the 5 classification of fire?

The five main classes of fire, categorized by fuel type, are Class A (ordinary combustibles like wood/paper), Class B (flammable liquids/gases like gasoline/propane), Class C (energized electrical equipment), Class D (combustible metals like magnesium/titanium), and Class K (cooking oils/fats in commercial kitchens), with Class K often replacing older systems for kitchen fires, while some regions use Class F or E (electrical). 

What is the 4 triangle of fire?

Oxygen, heat, and fuel are frequently referred to as the "fire triangle." Add in the fourth element, the chemical reaction, and you actually have a fire "tetrahedron."

ABC extinguishers are versatile for common fires (wood, liquids, electrical) but leave messy powder, while CO2 extinguishers are residue-free, ideal for electronics and liquids (B & C fires), offering a strong cooling effect but less range and danger in confined spaces due to oxygen displacement. Choose ABC for general hazards, but CO2 for sensitive equipment like servers or laser engravers where clean-up is critical.
 

Do I need a 5 lb or 10 lb fire extinguisher?

A 10lb fire extinguisher offers significantly more firefighting power, longer discharge time, and greater reach than a 5lb unit, making it better for larger spaces like workshops, garages, or commercial areas, while the lighter 5lb extinguisher is sufficient and easier to handle for average-sized rooms in homes or smaller settings. Key differences are capacity (10lb has nearly double the agent), discharge duration (10lb lasts longer, around 22s vs. 5lb's ~20s), and application (5lb for average rooms, 10lb for higher-risk or larger areas needing more suppression time).
