1. Requirement for Torch Operators
• Question: All torch operators, an oxygen-fuel torch using any amount of oxygen
and flammable gas, and fire guards must have a current:
• Answer✅: Certificate of Fitness
• Rationale: The Fire Department of New York (FDNY) mandates a Certificate of
Fitness (such as the G-60) to ensure that individuals handling highly dangerous open
flames and pressurized gases have proven their competency through testing to prevent
hazardous industrial accidents.
2. Responsibility for Gas Regulation
• Question: The Certificate of Fitness holder:
• Answer✅: Must regulate the pressure and flow of oxygen and natural gas to each
torch.
, • Rationale: Pressurized gases can become volatile if unbalanced. The C of F holder is
trained to safely monitor gauges and adjust ratios to prevent dangerous backfires,
flashbacks, or structural failure of the hoses.
3. Jewelry Manufacture Regulation
• Question: If the torch operator for jewelry manufacture involves:
• Answer✅: Any oxygen with any fuel gas containers, the operator must be a C of F
holder.
• Rationale: No matter how small the torch or scale of production, combining pure
oxygen with a fuel gas dramatically increases combustion rates. Therefore, it strictly
requires professional FDNY oversight.
4. Location of the Certificate
• Question: A Certificate of Fitness Holder must keep his or her certificate:
• Answer✅: On their person or otherwise readily available for inspection by any
representative of the Fire Department.
• Rationale: Inspectors must be able to instantly verify an operator's legal
qualifications on-site. Failing to produce a physical or easily accessible license can
result in immediate job site shutdowns and fines.
5. Resolving a Leak Emergency
• Question: The easiest way to extinguish a fire caused by a leak is to:
• Answer✅: Close the shutoff valve.
• Rationale: A fire needs fuel to survive. Extinguishing the flame without shutting off
the gas supply allows unburned gas to escape into the air, creating a massive, invisible
explosion hazard. Cutting off the fuel source at the valve safely neutralizes the fire.
6. FDNY Hot Work Permit Thresholds
• Question: Permits issued by the FDNY are required to conduct the following hot
work:
• Answer✅: Storing, using or handling oxygen and a flammable gas; storing, using or
handling any flammable gas (e.g., LPG, CNG, or acetylene) in excess of 400 SCF;
storing, using or handling any oxidizing gas (e.g., oxygen) in excess of 504 SCF.
• Rationale: Large volumes of compressed gases present a severe risk of catastrophic
explosion during a structural fire. The FDNY tracks these locations using permits to
ensure proper storage safety compliance.
, 7. LPG Weight Conversion
• Question: For LPG, 400 SCF is:
• Answer✅: Approximately 47 lbs.
• Rationale: Fire codes regulate gases by volume (Standard Cubic Feet), but
commercial gas cylinders are sold and measured by weight. Knowing that 400 SCF
equals roughly 47 pounds helps operators quickly calculate if their total tank
inventory exceeds permit thresholds.
8. Container Limits Requiring a Permit
• Question: What is the specific number of LPG containers for the storage, use,
handling, or transportation that triggers a permit requirement?
• Answer✅:
o 14.1 oz = 54 containers
o 16.4 oz = 46 containers
o 20 lbs = 3 containers
o 33.5 lbs = 2 containers
o 40 lbs = 2 containers
o 100 lbs = 1 container
• Rationale: Small, individual consumer camping or plumbing canisters present less
aggregate risk than large industrial tanks. This tiered system mandates a permit the
moment the cumulative volume across specific container sizes becomes hazardous.
9. Indoor Storage Restrictions
• Question: Portable LPG containers that are more than 16.4 oz and CNG
containers with a capacity greater than 8.7 SCF:
• Answer✅: Must NOT be stored, handled, or used indoors in the following
occupancies (as defined in the Building Code): residential occupancies; factory and
industrial occupancies; educational occupancies; institutional occupancies, except as
the commissioner may authorize by rule.
• Rationale: Liquid Petroleum Gas (LPG) is heavier than air and sinks to the floor if it
leaks, pooling in basements or low areas and creating a highly susceptible explosion
environment. This makes heavy indoor storage strictly illegal in high-density or high-
risk buildings.
10. Site-Specific Permits
• Question: Site-specific permit:
