Occupational Health And Safety Ngc 2 (Element 6)

Front 1

Explain how friction may start a fire.

Back 1

Friction is process whereby heat is given off by 2 materials moving against one another. In the absence of a lubricant or cooling substance it can result in the surfaces of the materials beconing hot or actually producing sparks, either of which may be sufficient to cause ignition.

Front 2

How may space heater cause a fire?

Back 2

It is designed to give off considerable heat & close to the heater, temperatures may be high. Fire may be caused by combustible materials being placed too close to the source of heat ( through radiation) or by obstructing the air intake intake into the heater.

Front 3

What happens if you open a window in a fire?

Back 3

The smoke may begin to clear but by allowing frash air into an oxygen-depleted environment, the fire is likely to burn with increased intensity.

How to minimise risk of fire in woodworking area?

Back 14

Wood shavings & dust cleared regularly.
Ensure ignition sources e.g cigarettes & sparks from electrical equipment do not come into contact with combustible materials.

Front 15

Precautions when using flammable liquids?

Back 15

Minimise volume used at any one time.
