Fire is a rapid chemical reaction that produces heat, light, and combustion, typically involving oxygen and a fuel source.

• Fire requires three elements: heat, fuel, and oxygen (the fire triangle).

• Examples of fuels include wood, gasoline, and natural gas.

• Fire can be classified into different types: flames, smoldering, and explosive.

• It can cause destruction but is also used beneficially in cooking and energy production.

• Fi...read more

PASS is a fire extinguisher acronym for Pull, Aim, Squeeze, and Sweep, guiding effective fire suppression.

• Pull the pin: This unlocks the extinguisher and allows you to use it.

• Aim low: Point the nozzle at the base of the fire for effective suppression.

• Squeeze the handle: This releases the extinguishing agent.

• Sweep side to side: Move the nozzle from side to side until the fire is out.

Color codes are standardized colors used to convey specific safety information in various industries.

• Red: Indicates danger or emergency, such as fire alarms or stop signs.

• Yellow: Caution, often used for warning signs or to indicate potential hazards.

• Green: Safe conditions, such as first aid kits or emergency exits.

• Blue: Mandatory actions, like wearing personal protective equipment (PPE).

• Orange: Indicates a warning, oft...read more
