Choosing the right fire extinguisher may help you to stop the fire successfully. To defend the fire, the only option you have is that fire extinguisher to restrict fire spreading. A fire extinguisher is a device used for fire safety to extinguish small fires or flame in an emergency situation. A fire extinguisher is not intended for use in a large scale fire. Normally, a fire extinguisher is a hand-held pressurised cylinder having an agent such as nitrogen.
Why is fire dangerous?
There is a presence of oxygen that supports them during a fire. Fuel burns reacting with oxygen from the nearby air and discharging heat, gas, smoke etc.
Maybe you would like to think that it is easy to keep our sense in a fire to do the right thing. You can feel that heat can be 12 times increased from floor level to ceiling. And your skin could be permanently injured with just 160 degrees, whereas the heat of the fire may reach up to 1200 degrees at the ceiling.
Low positioning will give you some space to see and breath better. High heated air inhaling may scorch your lungs, even can cause anyone’s death. The rage of fire and thick black smoke may cause blindness in the fire environment. Fire will be lessening by the closing door.
What is fire safety?
Fire safety is the assembly of methods aimed at reducing fire damage. Fire safety initiatives intended to restrict fire from sparking and after-fire effects.
You have to know the workplace fire safety laws and legislation. Using safety signs can lessen the risk of your company or organisation. As an employer, you need to take proper steps to lessen the risk made under the Management of Health and Safety at Work Regulations 1999. Timing and placement of using safety signs will help to further reduce this residual risk.
The Fire Classification System in the UK
Why do you need to know about the Fire Classification System around you? If you are a citizen of the UK, knowing this fire classification system will help you to choose the proper fire extinguisher. Based on fuel burning, you will catch up with 6 different fire classification systems.
There are 6 fire classes you will consider in the workplace.
Class A: Ordinary combustible fires
Most of the time, you will find a cause of burning Ordinary combustible fires are the most common type of fire. Ordinary combustible fire happens when the materials are heated and will continue until the heat, oxygen and fuel are available. Materials that are used in the form of fires include paper, wood, textiles, rubber, plastics, and other organic carbon-based components.
Class A fires are simplest to extinguish because water spraying would cool the fire. Water-based or foam fire extinguishers are ideal extinguishing ordinary combustible flames.
Class B: Flammable liquids
Class C: Flammable gases
Class D: Metal fires
Class E: Electrical Fires
Malfunctions and overflowing switchboards, damaged appliances may trigger electrical fires. Electrical flames are not specifically a fire category with their own, because electricity is a means of combustion rather than a fuel. Nevertheless, they are also relevant to remember, because they have their own unique criteria for fire protection.
Carbon dioxide and dry powder fire extinguishers are the suggested extinguishers for attacking electrical fires.
Class F: Cooking oil fires
Cooking oil and fats are widespread materials available in households, companies and professional kitchens. Extreme temperatures are involved in the kitchen environment. As a result, it is a really challenging task for you to extinguish. To cool the fire, using only water will not work.
Distinct fire extinguishers (wet chemical extinguishers) typically used to address Class F fires.
In that panic situation, you need fire extinguishers to put out small fires. Smoke and burning extracts may limit air pollution by the fire extinguishers. You will need three things to use your fire extinguisher: COURAGE, CALM and the EXTINGUISHER.
There are a few fire extinguishers are listed below that you should know:
Safety signs are symbols that include details or guidance on protection at work by means of a label, a colour or an acoustic signal, a verbal or hand gesture. Signboard provides information or directions using different figures, colour and symbol or icon that are visible by lighting.
The Regulations in the UK require employers to guarantee that fire safety signs are placed in a proper position. Fire safety training is a must for all organisations and employees such as leaders, managers and supervisors.
Safety Signs can be of the following types:
Sign that restricts activity which can be an increase or trigger danger such as no access for unauthorised persons.
A sign that gives warning of danger for example danger: electricity.
A sign that recommends specific behaviour such as eye protection must be worn.
Emergency escape or first-aid sign
Sign that provides information on emergency exits, first aid, or rescue facilities such as emergency exit/escape route.
A regulation on signs incorporating certain colours have specific meanings.
According to UK The Health and Safety (Safety Signs and Signals) Regulations 1996, there are some colours, meaning and instruction on safety colours. Learn more from the HSE website.
|Colour||Meaning or purpose||Instruction|
Goes off when there is significant heat in the premises.
Be careful; take precautions; examine .
Specific behaviour or action, eg wear protective equipment.

Steps for using a fire extinguisher
Research data shows that portable fire extinguishers were 95% effective in alleviating fire.
There are mainly four steps to use a fire extinguisher. Remember the Acronym P.A.S.S. as follows —
Pull: Know how fire extinguisher is classified. Class A extinguisher for ordinary things such as paper or wood. Class B for flammable liquids and Class C for electrical fires. The red cross recommends to pull out the safety pin or label. After that, the fire extinguisher is ready to confront the fire flame.
Aim: Now, you should aim at the bottom or base or source of the fire. This aiming mainly works on the fire triangle. Burning causes from a different source such as fuel, oxygen etc. If you are aiming at fires instead of a source of the fire, the extinguisher will not break down the continuity of fire flames.
Squeeze: Slowly squeeze the trigger till the extinguisher starts to work. Check the pressure gauge. The pressure gauge measures the charge of a fire extinguisher.
Sweep: Backward and forward sweep of fire extinguisher over the firebase until the extinguisher went empty.
