2 Kettle fires Storage of flammables near heat sources Mechanical equipment fires Flash over with primer wash Building fire caused by customer Cigarette smoking on the roof or around flammables Sparks from cutting metal deck Electrical fires or exposed wires Smoldering asphalt under roof

3 3 Components of fire: 1. Fuel 2. Heat 3. Oxygen All three components are needed for a fire to survive! Take one of the three away, the fire will not survive!

4 CLASS A - Ordinary Combustibles CLASS B - Flammable or Combustible Liquids CLASS C - Electrical CLASS D - Combustible Metals

5 Examples; Paper Insulation Dried Adhesives Fiberboard Clothing Wood Deck

6 Examples; Gasoline Primer Wash Splicing Cement Adhesives Coatings Propane

7 Points to remember: Never use water to extinguish! Check all cords and equipment before use De-energize when not in use Exposed wires are a fire hazard

8 Class A - For class A fires only Class B - For class B fires only Class AB - For both class A and B fires Class ABC - For class A, B, and C fires

9 At least one 10 pound fully charged ABC extinguishers for all roofing projects When a kettle is present, an additional 10 & 20 pounds of ABC extinguishers are required

10 What type of fire is this going to be?

11 1. 2. Which is the proper extinguisher to use for suppression of the previous fire?

12 P. A. S. S. System 1Pull - Pull pin

13 2Aim - Aim nozzle at base of the fire 3Squeeze - Squeeze the handle together

14 4S weep - Sweep back and forth

15 Fire extinguishers can save lives and property Only attempt to extinguish a fire if it is safe and you have been trained on proper use Evacuate the roof if the fire is out of control

16 Recommended Procedure Shut the lid Shut off the fuel source Remember to do both! Use extinguisher when: Fire is no longer contained in kettle Fire is out of Control *NEVER use water!

17 Review escape plan before work begins Never set up the kettle near access to the roof Keep the fire extinguishers in your work area Foremen, keep cell phone on you at all times

18 Proper Torch Assembly –Follow all Manufacturer’s Recommendations –Use only approved connection equipment –Hand tighten parts and do not force connection –Use open end wrench to complete assembly –Do not use any type of thread sealant as they may be flammable

19 Inspect all equipment for damage before use Inspect propane cylinder for dirt Close cylinder valve tightly Attach torch following Manufacturer’s Recommendations Complete leak test using soapy water –Leaks will cause bubbles to form

20 If leak is detected, close cylinder valve and disconnect all parts –Attempt to reassemble –If leaks still exist, discontinue use and replace torch Never use open flame to check for leaks!

21 Wear required PPE –Eye protection, gloves, long clothing to cover skin Prepare work area by clearing away debris Have extinguishers present and secure propane tank Alert other workers and keep them away Open cylinder and keep torch away from body Use striker to ignite gas and adjust flame –NEVER USE CIGARETTE LIGHTERS OR MATCH

22 Always assume a torch at rest is lit Use leg stand to support torch Shut torch off when not in use Never leave torch unattended Never operate within 3 feet of other workers Never point torch towards flammable objects or areas you can not see clearly

23 Use caution when using torch around: –Roof openings, units & drains –Roofing materials and combustible deck

24 Never turn propane cylinder on its side –This does not increase fuel supply and is dangerous Never apply open flame to defrost cylinders Use caution when walking backwards –Use all required fall protection –Be aware of your surroundings –Have another employee serve as spotter

25 Always disconnect torches at end of work day Inspect all components for damage Replace damaged components Set torch on side and close cylinder valve Squeeze torch trigger to purge remaining gas Close all valves and disconnect torch Properly store equipment & secure cylinders

26 When cutting through metal deck: –Mark off 10ft area below –Have a crew member stand below outside marked area to watch for smoke and fire –Supply him with a hard hat, safety glasses, and a fully charged ABC rated fire extinguisher

27 -Fire Extinguishers -Gas Cans (no plastic) -Propane tanks -Strikers -Material Labeling -GFCI

28 All flammable and combustible materials must be properly labeled Labels should be kept clean and easily noticeable All D.O.T. vehicles must have proper placards Never remove or alter labels

29 FIRE HAZARD Flash Points: 0-Will not burn 1-Above 200 o F 2-Below 200 o F 3-Below 100 o F 4-Below 73 o F

30 Each truck (1) 5lb. Extinguisher Upright and secure (includes all flammables and extinguishers) Out of or away from heat NO SMOKING –On roof! –In truck or van! –Around storage areas!

31 Hot Pipe Secure to 8’ Rail 20 lb. Fire Extinguisher Rubber Matting Under Kettle Area Flagged Off Correctly Building Tarped Asphalt Stored Neatly Propane Secure 10’ from Flame Proper PPE Worn Wheels Chalked No Windows

32 Area flagged off 20 lb. Fire extinguisher present Fuel set 10 feet from ignitable source & secured in place Plywood under kettle if set on new roof Proper PPE worn

33 PPE Required for Kettle Operations: Hardhat with Attached Face Shield - the face shield prevents splashes from reaching the face and upper neck Leather Gloves - cuffs must be long enough to be tucked under sleeves Long Pants with No Cuffs - cuffs on pants may hold asphalt and allow it to burn you Long Sleeved Sweatshirt - preferably hooded to protect the back of your neck

34 While working with hot asphalt on the roof employees must wear:Leather gloves, Safety glasses, Long sleeved shirt, Long pants w/ no cuffs, and proper boots * Never use glue buckets or primer wash cans to transport hot, only hot buckets or approved containers Note: When pouring asphalt from pipe, a face shield is also required to be worn

36 STAY CALM! What to tell operator: –Callers name – Location –What happened –Conditions of those affected –Type of first aid given, if any Remain on line until dispatcher hangs up Send someone to meet EMT’s

37 -Assess situation -Stop, drop, and roll -Smother area with jacket -Use extinguisher, only if necessary -Notify Supervisor SCENARIO #1-A coworkers clothes are on fire!

38 Evacuate everyone Pull alarm in building Call 911 Take roll call on ground Notify Supervisor Fill out paper work SCENARIO #2 - Fire is out of control!

39 Assess situation Use potable water to cool burn Notify Supervisor Apply clean dressings from first aid kit Seek medical attention SCENARIO #3 - Coworker is burned by hot asphalt!

40 Always use caution with flammable materials and open flames Think Safety First to avoid burns Fire watch is needed for spark generating work Only use strikers to light torches Never use gasoline to clean hands Only you can prevent roof fires!
