Fire Safety Tips - Workplace

• Do not utilize electrical gear that is in poor condition or that has a harmed line. 
• Do not over-burden circuits or electrical lines, read makers determinations. 
• Utilize affirmed control bars rather than circuit splitters. 
• Keep all warmth delivering machines far from the divider and far from anything that may blaze.  
• Leave a lot of space for air to circle around gear that typically emits warm. 
• Guarantee little apparatuses, for example, warmers, fans and so forth are closed off before leaving the building. 
• Ensure all apparatuses, for example, espresso producers and hot plates, are killed when not being used. 
• Toasters and microwave broilers ought to be situated in kitchen regions as it were. 
• Maintain a strategic distance from profound fat broiling, or utilize an indoor regulator controlled apparatus and never abandon it unattended. 
• Keep every single flammable material, for example, paper towels and fabrics, at a protected separation from warmth sources. 
• Keep stockpiling zones, stairway arrivals and other out-of-way areas free of waste paper, exhaust containers, filthy clothes and other material that could fuel a fire. 
• Guarantee office entryways and subordinate office entryways, for instance, document room and lobby entryways, are shut while leaving the building. 
• Guarantee warm registers are clear of burnable things, for example, paper at all times.

Common Causes of Fire in Businesses

Open Flames

• negligence in conducting hot work, such as welding, cutting or grinding; 
• improper use of candles;
• improper handling of flammable or combustible liquids or flammable gases in near-to-potential ignition sources; and
• matches and cigarettes that are improperly disposed of, or left unattended near combustibles.

Electrical

• damaged electrical conductors, plug wires or extension cords;
• use of faulty, modified or unapproved electrical equipment;
• insufficient space or clearance between electrical heating equipment and combustibles;
• short or overloaded circuits;
• loose electrical connections; and lighting.

Cooking

• deep frying in pots or pans on stove tops;
• unattended cooking appliances; and
• combustibles located dangerously close to cooking equipment.

Spontaneous Ignition and the Ignition of Waste Materials

• improper disposal of materials susceptible to spontaneous combustion, such as oily rags from wood finishing or polishing;
• accumulation of organic materials, such as green hay, grain or woodchips; and
• accumulation of waste combustible materials near potential sources of ignition.

Gas Safety

Gas through the mains is highly dangerous and explosive if not used correctly.

• Only competent persons can touch either gas installations or gas-fuelled equipment.
• They must be Corgi Registered to carry out the tasks required (Domestic or Commercial).

Control measures include:

• Having a gas leak (or suspected gas leak) procedure
• Equipment must be regularly serviced
• All defects to equipment or installations must be reported - may need to follow gas leak procedures
• The gas shut off valve (which switches off the main gas supply) must be in an accessible position
• The room or area in which the gas appliance is situated must have good ventilation
• The equipment must be sited/used in a well-lit area
• Staff must receive information, instruction and training

Electrical Safety

Approximately 30 people at work die every year as a result of electrocution. The majority of these deaths are caused by contact with overhead or underground cables.

The main hazards from electricity:

Electric shock - the effect on the body and central nervous system produced by the passage of the electric current. Common cause of death is ventricular fibrillation (spasm of the heart muscle). The vascular system ceases to function and the victim dies of suffocation. It’s the current that kills.

Burns - a current passing through a conductor (the person) produces heat. Burns can be caused by contact with hot conductors, e.g. metal, or by the passage of the electric current through the body.

Explosions - electrical short-circuiting or sparking from the electrical contacts in switches or other equipment. There needs to be combustible material, e.g. flammable vapours, dusts or gas.

Eye injuries - exposure to ultraviolet rays from accidental arcing in a process such as welding

Accumulators and batteries - hydrogen gas may be produced as a by-product of battery charging. This results in a potentially explosive atmosphere.

Electricity - Fire Safety

Safe Systems of Work

Where work is to be undertaken on electrical apparatus or part of a circuit, a formally operated, safe system of work is essential. This commonly takes the form of a Permit to Work system, which ensures the following procedures and precautions:

• Switching off and locking out the electricity supply, i.e. isolation;
• Checking by the use of an appropriate voltage detection instrument that the circuit, that part of same to be worked on, is dead before work commences;
• High levels of supervision and control to ensure that work is undertaken correctly and that Permit to Work procedures are followed;
• Paying particular attention to the precautions where electrical installation or maintenance work is to be undertaken in wet surroundings, in external areas and in confined spaces;
• Examining appliances by a competent person on a regular basis, including the leads, and any extension leads used that may have become damaged;
• Implementing physical precautions, such as the erection of barriers and signs restricting access to the area; and
• Formal cancellation of the Permit to Work once the work is completed satisfactorily and return to service of the appliance, plant or system in question.

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.
