• When a fire is detected, the system activates audible and visual alarms to alert people to evacuate the premises.

• Fire alarm systems can be...read more

There are several types of fire alarms, including ionization, photoelectric, heat, and combination alarms.

• Ionization alarms detect fast-burning fires with small smoke particles.

• Photoelectric alarms detect slow-burning fires with large smoke particles.

• Heat alarms detect high temperatures and are often used in kitchens.

• Combination alarms use both ionization and photoelectric sensors for comprehensive coverage.

• Other types of alarms include carbon monoxide detectors and smart ala...read more

A fire extinguisher is a portable device used to control or extinguish small fires.

• Fire extinguishers contain a pressurized substance that is expelled to suppress or extinguish fires.

• They are typically classified based on the type of fire they are designed to extinguish, such as Class A, B, C, D, or K.

• Common types of fire extinguishers include water, foam, carbon dioxide, dry chemical, and wet chemical extinguishers.

• Fire extinguishers should be regularly inspected, maintained...read more

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.

There are several types of fire, including Class A, Class B, Class C, Class D, and Class K fires.

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

• Class B fires involve flammable liquids or gases like gasoline, oil, and propane.

• Class C fires involve energized electrical equipment like appliances, wiring, and circuit breakers.

• Training building occupants on fire safety procedures

There are several types of fire sprinklers, each designed for specific applications and environments to effectively suppress fires.

• 1. Wet Pipe Sprinklers: Most common type, filled with water at all times. Example: Standard commercial buildings.

• 2. Dry Pipe Sprinklers: Filled with air, water released when air pressure drops. Example: Unheated warehouses.

• 3. Pre-Action Sprinklers: Requires two triggers to activate, often used in sensitive areas. Example: Data centers.

• 4. Deluge Sp...read more

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

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