Required for any project with hot work operation but not issued by the FDNY Responsible person Must be available for inspection by any representative of fire department during and 48 hours after the work is complete. Fire guard Cof holder who is trained in and responsible for maintaijjng a fire watch. Fire watch Survailance of an area Detect signs of early fire Raise alarms Notify department Pre hot work check must be conducted by the responsible person before hot work is authorized at least? Once per day Pre hot work check daily and must very the following Equipment working in order Hot work is clear of combistibles and flammable solids Combustible and non combustible are protected Fire watch personel are assigned Fire extinguisher available Fire watch A fire watch must be maintained during any hot work operation. The person conducting a fire watch shall Not have other duties Fire watch At least one portable fire extinguisher with a Minimum 2-A:20-B:C rating shall be accessible within 30ft from hot work Fire watch Exception roofing operating fire extinguisher 3-A 40-B:C Fire watch for torch operations conducted at following locations by a F-60 fire guard: Construction sites Buildings and structures Rooftops Fire watch must continue for 30 minutes after the conclusing of the work. Time and record keeping requirements CNG or LPG torch operations inspections First shall be conducted 30minute after completion Second inspection 1 hour after completion The inspection report must be available 48 hours after work is complete for fire department representative to look over. Oxygen cylinder is made of Steel and contains 100% oxygen Oxy propane degrees 1,500 degrees Acetylene degrees 3000 degrees Oxy-acetylene degrees 6000 degrees Brazing and soldering temperatures Typically 840 degrees Oxy-fuel torch Oxygen storage pressures up to 2200 PSI (pounds per square inch) Oxy-fuel torch Dangerous fuel gas pressures Above 15 psi especially for acetylene Gas torches also have applications and additions like For burning weeds Melting ice Applying tar/asphalt Backfire Flame on torch goes out unexpectedly A loud snap or pop may occur when the flame goes out. Flashback Cutting or welding flame burns inside the torch or the hoses. It is usually accompanied by a whistling or hissing noise. Frayed clothing Susceptible to ignition and burning, should not be worn. Compression gas container Dangerous temperatures High temperatures 125 degrees Regulator Most important part of compressed gas systems. Fire guard A person holding a certificate of Fitness for such purposes, who is trained in and responsible for maintaining a fire watch and performing such fire safety duties as may be prescribed by the commissioner Fire Watch A temporary measure intended to ensure continuous and systemic surveillance of a building or portion thereof by one or more qualified individuals for the purposes of identifying and controlling fire hazards, detecting early signs of fire, raising an alarm of fire, and notifying the department Hot Work Cutting, welding, thermit welding, brazing, soldering, grinding, thermal spraying, thawing pipe, cadwelding, installation of torch - applied system or any other similar operation or activity Hot Work Area The area exposed to sparks, hot slag, radiant heat, or convective heat as a result of hot work NFPA National Fire Protection Association. The world's leading advocate of fire prevention and an authoritative source on public safety, NFPA develops, publishes and disseminates more than 300 consensus codes and standards intended to minimize the possibility and effects of fire and other risks Personal Supervison Supervison by the holder of any department certificate who is required to be personally present on the premises, or other proximate location acceptable to the department, while performing the duties for which the certificate is required Responsible Person A person trained in the fire safety hazards associated with hot work, and in the necessary and appropriate measures to minimize those hazards, who is designated by the owner of a premises to authorize the performance of hot work at the premises Torch - applied roof system Bituminous roofing systems using membranes that are adhered by heating with a torch and melting asphalt back coating instead of mopping hot asphalt for adhesion oxygen-fuel gas torches have two separate containers: a pressurized fuel gas container and a pressurized oxygen container. The oxygen cylinder made of steel and contains 100% oxygen. A mixture of oxygen and a fuel gas is used to generate a flame oxygen intensifies the burning of the fuel gas. Oxy-propane torches can produce about _____ degrees Fahrenheit higher than the air-propane torch can generate 1,500 Acetylene is used because compared to the other fuel gases it creates the greatest amount of heat when burned (i.e. 3,000 degrees Fahrenheit higher than an air-propane torch) Both gas containers have control valves on the ___ of the container. top The valves control the discharge of gas from the containers Gas containers also have a protective cap or protective collar. when the cylinders are not in use The caps should be screwed on over the valve The oxygen is stored at pressures up to 2200 psi The fuel gas is stored at higher pressures to keep sufficient amount of fuel available for torch operations it is dangerous to use the fuel gas at pressures above __ psi, especially for _________ 15, acetylene. The regulator makes sure that fuel is discharged from the gas container at a safe pressure range The two gases, _______ and the ________, are mixed inside the torch oxygen, fuel gases
