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.
