Question

40 During any fire incident, it is advised to

(a) wrap a towel or woollen blanket over the burning object

Answer 1

• Fire or burning is supported by air (oxygen).
• In order to stop it, a towel or woollen blanket is used because the air holes in a woollen blanket act as an insulating medium, cutting off the flow of oxygen to a burning object, and preventing it from any further burning.
• As this supply is cut off, the fire eventually stops.
