Know your fire classes (A to F)

Fires are classified by the type of burning material, and using the wrong agent can be dangerous. RUFO's multipurpose dry powder is effective across a wide range of these classes.

Class A — solids

Fires of wood, paper, cloth and plastic. The most common type of fire in homes and offices.

Class B — flammable liquids

Petrol, oil, paint and solvents. Water must never be used here as it spreads the fire.

Class C — gases

Fires from natural gas, methane and propane. Shutting off the gas source is the first vital step.

Class E — electrical

Fires in electrical panels, electronics and servers. The agent must be non-conductive; RUFO's dry powder is ideal for this.

Class F — oils & fats

Cooking oil and fat fires. This class is very dangerous in domestic and industrial kitchens.
