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.
