Reasons Why Spread Fire - Fire and Safety

Reasons Why Spread Fire ?

1. Failure of Early Detection
2. Absence of Compartments in Building Structure
3. Compartments Undermined
4. Materials Inappropriately Stored 
   

1. Failure of Early Detection

Early detection of fire spread can be delayed by:

• No detection system or patrols
• No alarm system in place
• People not knowing or confusing the sound of the alarm
• Not promptly extinguished due to no hoses or extinguishers
• Fire Starts in Unoccupied area
• Fire Starts out of normal work hours
• Numerous hot working tasks conducted - therefore smells of burning ignored

2. Absence of Compartments in Building Structure
Fire spread within a building can result from an absence of compartments:

• Open plan office
• False ceilings
• The structure under construction or alteration is complete and has reduced separation between levels and/or sections on a level.

3. Compartments Undermined
Fire Spread within a building can result compartments being undermined:

• Fire doors wedged open
• Poor maintenance of door structure
• Holes may be designed to pass through compartments and are waiting fitment of services and subsequent sealing
• Holes cut for ducts or doorways or to provide temporary access to locate/remove equipment.
• Compartments may be progressively created in buildings under alteration, thus increasing the risk of fire spread.

4. Materials Inappropriately Stored
Inappropriate storage of materials can cause of fire spread:

• Flammable liquids not controlled - too much or in unsuitable containers.
• Boxes in corridors, under stairways or in access routes.
• Off cuts of wood and saw dust left in the area where work has taken place.
• Packing materials used in the process, such as shredded paper, polystyrene, bubble wrap, etc.,
• Pallets and plastic covering left near to ignition sources.

Fire Extinguishers

Be set up for any accidents by having fire extinguishers deliberately put around your home — at least one on every floor and in the kitchen (this one should be a generally useful extinguisher, which means it can be utilized on oil and electrical fires), the basement, the carport, or workshop area. Keep them out of reach of children.

Fire extinguishers are best used when a fire is contained in a small area, like a wastebasket, and when the fire department has already been called. 

The NFPA says to remember the word PASS when operating an extinguisher:

• Pull the pin. Release the lock with the nozzle pointing away from you.
• Aim low. Point the extinguisher at the base of the fire.
• Squeeze the lever slowly and evenly.
• Sweep the nozzle from side to side.

The best time to figure out how to utilize the fire extinguisher is now, before you ever require it. fire extinguisher have gauges on them showing when they should be checked regularly to make sure they're still functional.

In case you're ever in uncertainty about whether to utilize a extinguisher on a fire, don't attempt it. Rather, go out instantly and call the fire department.
