3 Domestics Fire alarm sound / test / drill / nearest fire point Toilets Duration of session
4 Use of a fire extinguisher is VOLUNTARY! Important!Use of a fire extinguisher is VOLUNTARY!
5 Chemistry of fireFor fire to exist, the following four elements must be present:Enough oxygen to sustain combustion Enough heat to raise the material to its ignition temperature Some sort of fuel or combustible material, and The chemical reaction that is fire.Take away any of these and the fire will be extinguished
6 How fire spreads Direct burning – chemical reaction Convection RadiationConductionFire CreepBurning material falling onto other combustible materialsFlashover
7 Ways of fighting fire: Leave it to the experts! Cooling Suffocating Removing the fuel (Starving)
8 Classes of fireFires are classified according to the type of fuel that is burning.Using the wrong type of fire extinguisher on a fire may make matters worse.The five different fire (fuel) classes…Solids – class A fire – paper, wood, textiles etcLiquids or liquefiable solids – class B fire - petrol, diesel, hydrocarbonsGases – class C fire – flammable gasesMetals – class D fire – Magnesium, TitaniumCooking oil fires – class F – deep fat fryers, commercial kitchens etcWhat about fires in electrical equipment?
9 How an extinguisher works Portable fire extinguishers apply an extinguishing agent that will either:cool burning fueldisplace or remove oxygen, orstop the chemical reaction so a firecannot continue to burn.When the handle of an extinguisher is compressed, it opens an inner canister of high-pressure gas that forces the extinguishing agent from the main cylinder through a siphon tube and out the nozzle. A fire extinguisher works much like a can of hair spray.
10 How to use an extinguisher … 1 Always raise the alarm first1. Pull the safety tag and pin2. Aim at the base of the fire3. Squeeze the handle levers4. Sweep the jet from side to sideIf you have the slightest doubt about your ability to fight a fire....EVACUATE IMMEDIATELY!
11 How to use an extinguisher …2 Use the right type of extinguisherKeep your escape route clear and your back to itGet within effective range but stay safeAlways be prepared to abandon the fight - if you don’t think it’s safe, escape!Speed is importantBeware - Noise, visibility, steam!Samples of Instructions
12 Types of extinguisher For use on solid organic (Class A) fires Normally 9 litre, weight about 12kgMust last 45s minimum, most only last around 90sDon’t use on oils, fats, live electricsFor use on Liquids (Class B) fires and fires in electrical equipmentBlack band denotes CO2Normally 2kg or 5kgNoise! Cold! Lasts around 30s
13 Types of extinguisher For use on Class A or B fires Foam or AFFF denoted by the cream bandUsually 6 or 9 litreIneffective on deep cooking oil fires, don’t use on live electricsFor use on Class A, B or C firesBlue band denotes powderNormally 2kg, 4kg or 6kgCan be similar size to water or foam/AFFFMessy! Visibility!
14 Types of extinguisher For use on Class A or B fires Make sure blanket covers fire!Other means of fire fighting: Sand buckets,Hose reels,
15 Beware …!Fires involving gas will reignite if the source is not isolated – explosion risk!If possible, turn off power before tackling a fire in electrical equipmentWhen is a fire small enough to tackle … or too large to deal with?One fire = One extinguisherBe prepared to abandon the fight if you don’t start to control the fire quickly
16 People fires … STOP, DROP, ROLL Don’t use extinguishers (maybe water mist?)Don’t flap or slap at the burning clothesReact rapidly / urgently but stay calmDon’t become a victim yourself6ft fire blankets in some laboratories
17 Risk Assessment? If you don’t feel safe – don’t put yourself at risk … Is the fire too big?Is the air safe to breathe?Is the environment too hot or smoky?Is there a safe evacuation path?If you don’t feel safe – don’t put yourself at risk …escape and call out the experts
18 Practical session … Using the Bullseye laser training equipment … What it is – a light-weight training device that can be used indoors or outside to simulate real firesWhat is does - laser-driven extinguishers simulate class A, B or C fires levels of severity.How to use it – P.A.S.S Aim at the base of the fire Sweep from side to side. Get close enough, stay low.
19 Practical assessmentTake it in turns to fight a fire and extinguish it using the right extinguisherDon’t take too long!Your speed and success will be recorded and will be put on your Certificate of Achievement!Be prepared for a re-ignition!Be prepared to abandon if you feel the fire is too severe.
