There are 6 classes of fire: Class A, Class B, Class C, Class D, Class K, and Class F.

• Class A fires involve ordinary combustible materials like wood, paper, and cloth.

• Class B fires involve flammable liquids like gasoline, oil, and alcohol.

• Class C fires involve energized electrical equipment.

• Class D fires involve combustible metals like magnesium and titanium.

• Class K fires involve cooking oils and fats.

• Class F fires involve cooking oils and fats in commercial kitchens.

Fire is a chemical reaction that produces heat and light. A fire pump is a device used to increase the pressure of water in a fire sprinkler system.

• Fire is a rapid chemical reaction involving fuel, oxygen, and heat

• Fire pumps are used to increase water pressure in fire sprinkler systems

• Common types of fire pumps include centrifugal pumps and positive displacement pumps

Fire work inside involves inspecting, maintaining, and repairing fire protection systems and equipment within buildings.

• Inspecting fire alarms, sprinkler systems, and fire extinguishers

• Testing and maintaining fire suppression systems

• Repairing any faulty equipment or systems

• Ensuring compliance with fire safety regulations

• Training building occupants on fire safety procedures

Fire door distance hazards refer to the potential risks associated with fire doors being too far apart.

• Fire doors should be spaced close enough to prevent the spread of fire and smoke.

• If fire doors are too far apart, it can create a gap for fire and smoke to travel through.

• Proper spacing of fire doors is crucial for containing fires and protecting occupants.

• Examples: If fire doors in a building are spaced too far apart, it can compromise the fire safety measures in place.

Fire is a rapid chemical reaction that releases heat, light, and various gases.

• Fire is a rapid oxidation process that produces heat and light

• It requires fuel, oxygen, and heat to sustain

• Different types of fires require different methods of extinguishing (e.g. water for Class A fires, CO2 for electrical fires)

• Fire can spread rapidly and be extremely dangerous

Fire and safety on site is crucial for preventing accidents and ensuring the well-being of individuals.

• Regular fire drills should be conducted to ensure everyone knows the evacuation procedures.

• Fire extinguishers should be easily accessible and regularly maintained.

• Emergency exits should be clearly marked and free from obstructions.

• Employees should be trained in fire safety protocols and procedures.
