Fire Extinguisher & Fire Hose Reel
Learning Objectives Cadets should be able to: Identify parts of an Extinguisher Apply the correct procedures of operating an Extinguisher Understand the advantages of using the Hose Reel Correctly operate a Hose Reel
Scope Introduction Types of Extinguisher Parts of Extinguisher Operating the Extinguisher Safety Precautions (Extinguisher) Hose reel System Using the Hose reel Safety Precautions (Hose reel) Practical Conclusion
IDENTIFICATION & PARTS OF EXTINGUISHER Fire Extinguisher: A fire extinguisher is a portable device specially designed to put out small fires. 3 Common types of portable fire extinguishers : 1.Water 2.Carbon Dioxide (CO2) 3.Dry Chemical Powder
Water Fire Extinguisher Suitable: Class A fires only
Parts of a Water Fire Extinguisher NOZZLE FLEXIBLETUBE CYLINDER DISCHARGELEVER CARRYING HANDLE PRESSUREGAUGE SAFETY PIN BASE
Carbon Dioxide Fire Extinguisher Suitable for: Class A*, B and C fires *Most effective for very small or confined-space Class A fires
Parts: Carbon Dioxide Fire Extinguisher CYLINDER BASE DISCHARGEHORN DISCHARGE TUBE SAFETY PIN DISCHARGELEVER CARRYING HANDLE
Dry Powder Fire Extinguisher Suitable for: Class A, B and C* fires *May corrode electrical equipment
Method of Operation 1. Carry the extinguisher to the site of fire 2. Pull out the safety pin 3. Aim the nozzle at the base of the fire 4. Squeeze the grip lever firmly 5. Sweep from side to side
Safety Precautions a. Do not use water extinguishers for Class B (flammable liquids and gases) and Class C (energised electrical fires) b. Keep a safe distance c. Do not stand facing the wind direction d. Stay out of thick smoke areas e. For electrical fire, remember to switch for power supply if possible f. Do NOT Hold the Discharge Tube when operating the CO2 Fire Extinguisher as it might lead to frostbite
HOSE REEL SYSTEM
HOSE REEL Minimise manpower One-man operated User friendly Minimal back pressure Suitable for use by most people Easy to operate/ be deployed Mobility Non-Kinking reinforced rubber about 30m long. Hose extends from 15m to 30m Strength 9m throw ( water dispenses to distance of 9m) Achievable flow rate of 0.4 liters/sec. ADVANTAGES :
HOSE REEL It is important to assess the type and source of fire before using a Hose reel to put out the fire! Type of FireHose reel suitability Class A (Solid combustible material) YES Class B (Flammable gases and liquid) NO Class C (Electrical fire) NO Class D (Reactive metals) NO
Checking of Hose Reel Check that there are no obstructions preventing the use of the Hose Reel. Check that the key to unlock the Hose Reel cabinet is housed on the cabinet.
Standard Fire Hose Reel enclosed in red cabinet. Notice key at the right corner KEY
1. Break glass covering to retrieve key 2. Unlock the cabinet door 3. Check that Hose Reel is intact and not tangled
4. Turn ON the valve to let the water flow (anti - clockwise direction )
5. Pull out the drum towards you The Drum can swivel left to right
6. Point the nozzle down and away
7. Turn the Nozzle Clockwise to test if the hose is working
Turn the nozzle carefully to control the amount of water gushing out Always point Nozzle down and away from you
8. Assistant to unwind the drum to extend the hose
Hose controller and assistant must cooperate Take Note!!!
Assistant must follow hose trail and ensure Hose is straightened
Assistant must keep hose reel in line of sight at all times
9. Assistant must keep Hose Controller within his view / line of sight
10. Hand ready to twist nozzle to turn on hose reel Note: Hose controller must keep low when approaching Fire
Hose Reel handler and assistant must not be standing on the same side of the hose. They should be on opposite sides of the hose.
Ensure the hose is not kinked!
Keeping the Hose Reel
1. When keeping the hose, ensure it is not entangled
2. Assistant will help to reel the hose into the drum Note: make sure the hose does not get entangled
Ensure Hose is reeled in neatly. Straighten the water Hose Assist in rolling up of the water Hose
4. Push hose reel drum into cabinet
5. Remember to shut off water supply.
6. Close cabinet door
7. Lock the cabinet and mount the key back on the key holder
SAFETY PRECAUTIONS Ensure that water supply is available before pulling out the hose reel towards the fire. Keep your position low whilst fighting fire in an enclosed area. In open areas, check for wind direction before moving towards the fire with the hose reel. Move in an upwind direction to avoid smoke and heat.
SAFETY PRECAUTIONS Do not use the hose reel to extinguish Class B (flammable liquids/gases) or C (energised electrical equipment) fires. In cases where you are trapped in a smoke logged situation, use the hose reel as a guideline to lead you out from hazard area. Use the hose reel to extinguish solid combustible materials only.
CONCLUSION By applying correct methods of extinguishing fire with proper firefighting equipment, you can save lives and properties!!
