What is AFA system?

What is AFA system?

Automatic fire detection (AFA) system provides warning of fire danger and permits counter-action to be taken usually before the danger has reached serious proportion. Already in its incipient phase, this type of fire is characterised by smoke and convection heat, as well as heat radiation.

What are the two systems of fire protection?

There are in fact two types of fire protection: Active Fire Protection (AFP) and Passive Fire Protection (PFP).

What are the 3 ways to extinguish a fire?

All fires can be extinguished by cooling, smothering, starving or by interrupting the combustion process to extinguish the fire. One of the most common methods of extinguishing a fire is by cooling with water.

What is a fire alarm strobe?

Strobes provide synchronized flashes to alert the hearing-impaired occupants to evacuate the premises. The higher the candela rating of a strobe device, the larger its coverage area. Horn strobes combine audible and visual alarms to alert the occupants to evacuate the premises.

What does AFA stand for in firefighting?

AFA: Automatic fire alarm/actuating fire alarm. Aircraft rescue and firefighting (ARFF): a special category of firefighting that involves the response, hazard mitigation, evacuation and possible rescue of passengers and crew of an aircraft involved in an airport ground emergency.

What is the difference between fire prevention and fire protection?

To briefly summarise, here are the main differences between fire protection, prevention and suppression: Fire prevention systems aim to minimize potential fire hazards. Fire protection reduces damage and helps to safely evacuate a building. Fire suppression systems are intended to extinguish the flames.

How do you stop combustion and extinguish a fire?

Removal of oxygen from the area around a fire can be achieved with a carbon dioxide extinguisher or a fire blanket. The carbon dioxide extinguisher pushes oxygen away from the fire and replaces it with carbon dioxide, which is inflammable and more dense than air.

What are the five main principles of fire?

Fire Extinguishment Principles

  • Cooling of Flame.
  • Reduction of Flame by cooling of the liquid; dilution of the liquid; or blanketing of the liquid.
  • Reduction of oxygen.
  • Interference with Combustion Reaction.
