Prohibition of smoking in manufacturing area.
Not operating electrical switches, when gas is smelled in the area.
Safety posters should be put on the notice boards.
Proper storage of combustible materials and removal of waste materials. 7 Slide 8: 6) Eliminating the ignition sources:
Electrical sparks & arcs Flames such as burner flames, matches & cigarette lighters & heaters.
Hot surface such as heated wires, rods or fragments.
7) Factory building should be made of fire resistant material like steel and ferroconcrete.
8) In order to exit in the emergency suitable exit facility to be provided.
9) Following all safety rules and precautions.
10) Fire alarms and fire extinguishers to be installed. 8 FIRE EXTINGUISHERS: : FIRE EXTINGUISHERS: Fire extinguishers work by:
Removal of oxygen from the site of fire.
Removal of heat by cooling with water or other extinguishing agents.
Water based fire extinguishers. (soda - ash extinguisher)
Water based foams. ( chemical foams and mechanical foams.)
Dry chemicals. (sodium bicarbonate, potassium bicarbonate.) 9 Slide 10: 10 CHEMICAL HAZARDS: : CHEMICAL HAZARDS: Toxic
