    Study Notes

    G-60 and F-60 Fire Guard Overview

    • G-60 pertains to hot work operations using oxygen and flammable gases like LPG or CNG.
    • Exceptions include COF for torch operations in jewelry.

    FDNY Permits and Regulations

    • A FDNY permit is required when storing, using, or handling more than 400 scf of oxygen or flammable gases and over 504 scf of oxidizing gas.
    • Types of permits include site-specific, citywide, and transportation permits.
    • Site-specific permits can be permanent or temporary, valid for up to 12 months.
    • Citywide permits last 30 days; temporary permits range from one day to 12 months, depending on operations.

    Hazardous Material Storage

    • Maximum storage quantities for hazardous materials are 5 gallons of gasoline, 250 gallons of flammable liquids, and 300 gallons of combustible liquids.

    Hot Work and Fire Watch Procedures

    • Hot work requires pre-hot work checks conducted daily by a responsible person.
    • A fire watch must be maintained before, during, and for 30 minutes after hot work.
    • Fire extinguishers must be accessible within 30 feet of the hot work area and must meet minimum rating requirements (2-A:20-B:C, 3-A:40-B:C for roofing).

    Equipment and Safety Protocols

    • Oxygen cylinders are made of steel and store oxygen at pressures up to 2200 PSI.
    • Oxy-acetylene torches can reach temperatures up to 6000 degrees Fahrenheit; oxy-propane torches reach about 1500 degrees Fahrenheit.
    • hazardous conditions include frayed clothing, which is more susceptible to ignition.

    Emergency and Fire Extinguishing Procedures

    • Classes of fire extinguishers are classified as A, B, C, and D for ordinary combustibles, flammable liquids, electrical equipment, and ignitable metals, respectively.
    • Fire extinguishers must be inspected monthly and maintained by an FDNY-approved company annually.
    • In case of a gas leak, shut off the gas supply before calling 911, or allow the flame to burn out if it’s unsafe to shut the supply.

    Responsibilities of Personnel

    • The responsible person must be available for inspection by fire department representatives for 48 hours after completion of the work.
    • Fire guards are trained personnel who maintain fire watch during hot work operations and ensure safety protocols are followed.
    • A COF holder must keep the Certificate of Fitness on their person or readily available for inspection.

    Inspection and Maintenance

    • Inspections of CNG or LPG torch operations are conducted 30 minutes and one hour after completion.
    • The inspection report must be available for fire department representatives within 48 hours after work is complete.
