fire safety tips & what you need to know

To illustrate the ingredients that a fire needs to initiate, fire safety experts have developed the fire triangle model.

 Fuel, oxygen and a source of ignition (heat) must be present for fire to exist. Once it has started, fire will produce a flame, smoke and heat. Smoke is made up of gases such as carbon monoxide (CO), carbon dioxide (CO2) and soot (small particles). The byproducts of fire are useful to detect the presence of fire. Most fire detectors will use one or a combination of heat, smoke, carbon monoxide or carbon dioxide to sense fire. 

Fire safety experts consider the fire triangle to be very significant for two reasons:

1. Fire Prevention – by keeping fuel, oxygen and heat apart, fire cannot start.

2. Fire fighting – by removing any of the elements when the fire has started, the fire will go out.

Experts have further classified fire based on the fuel type:  

Class A: Fire is based on solid materials such as paper, textiles and wood.

Class B: Fire is based on flammable liquids such as petrol, solvents and oil.

Class C: Fire is based on gases such as methane, acetylene and propane.

Class D: Fire is based on metals such as aluminum or magnesium.

Class F: Fire is based on high temperature fats and cooking oils. 

The classification informs the type of fire extinguisher to be used to put out fire. Some of the fire extinguishers that are recommended for use at home:

The common causes of fire are electrical equipment, deliberate ignition, hot work involving a naked flame, carelessly discarded smoking materials, cooking appliances, heating appliances, unsafe use and storage of flammable liquids and gases. 

Remember fire cause immense damage to homes and house contents. Items not directly destroyed by the fire are seriously affected by smoke. If you are insured, these losses can be recovered. However the consequences to people are irreversible. Most people killed are not killed by the flames directly but by smoke or carbon monoxide inhalation. Serious burns may also occur. It is highly recommended that you install smoke detectors in your home, house or premises to keep safe.
