Extinguish Fire - Fire Safety

How do you extinguish fires?

This involves the elimination of one side of the fire triangle.
Starvation - remove the fuel, e.g. turn off the gas supply, drag burning pallets away from the fire.

Smothering - remove the oxygen supply or adding inert gas (without oxygen) to the burning mixture, e.g. fire blanket onto a pan, or using a foam extinguisher. Main risk is that the fire may reignite when foam (wet chemical used for fat fryers) or blanket is removed as heat will still be present.

Carbon dioxide is commonly used in extinguishers and nitrogen is used in the petrochemical industry. Smothering is only effective when the source of oxygen is air. It is ineffective when the substance that is burning contains oxygen.

Cooling - commonest, cheapest and most effective method. For example,water sprayed onto a fire, will cause the temperature to be lowered. The steam produced acts as a blanket to smother reducing the potential for further ignition. Dry powder extinguishers rapidly absorb the heat and also smother.

Prevention of Slips and Trips - POSHE

Prevention of Slips and Trips

Slip  -  Too little friction or traction between feet (footwear) & walking / working surface, resulting in loss of balance

Trip 
– Foot or lower leg hits object & upper body continues moving, resulting in loss of balance
– Stepping down to lower surface & losing balance

Slips	Trips
Ensure floor has sufficient surface roughness, taking account of spillages and contamination.	Eliminates holes, slopes or uneven surface.
Eliminate contamination of the floor from water or food products, e.g: lips around tables, leak and spillage prevention, dry method to clean floors	Eliminate materials or objects likely to cause tripping
Prevent contamination of walkways, e.g. bunds around equipment, drainage channels, cleaning incoming footwear.	Eliminate the storage / location of equipment / materials in pedestrian walkways.
Limit the effects of contamination, e.g. Immediate treatment of spillages, good ventilation for dying.	Regular Housekeeping Regimes
Ensure cleaning regimes are effective and floor treatments are non-slip.	Eliminated or reduce the cause of floor damage, e.g. Pushing / Pulling trolleys.
Select suitable footwear.	Maintain the flooring conditions, e.g. Repair carpets, etc.
Eliminated or reduce the carrying of loads or pushing / pulling trolleys
