Question 1
All torch operators, an oxigen-fuel torch using any amount of oxigen and flamable gas and fire guards must have a current
Correct Answer
Certificate of Fitness
Rationale:
A Certificate of Fitness is required because it ensures that torch operators have the necessary knowledge and skills to safely use oxygen-fuel
torches, which involve handling flammable gases and pose a significant fire hazard. This certification validates the operator's competence in
preventing accidents and protecting themselves and others from potential dangers.
Question 2
The Certificate of Fitness holder
Correct Answer
must regulate the pressure and flow of oxygen and natural gas to each torch.
Rationale:
This statement is relevant because a Certificate of Fitness holder is typically an operator of a cutting and welding operation, who requires
precise control over oxygen and gas pressures to ensure safe and controlled combustion. Regulating these pressures is essential for preventing
accidents and maintaining a safe working environment, which aligns with the responsibilities of a Certificate of Fitness holder.
Question 3
if the torch operator for jewelry manufacture involves
Correct Answer
any oxygen with any fuel gas containers, the operator must be a C of F holder.
Rationale:
This requirement is based on the need for the operator to have a thorough understanding of the hazards associated with oxygen-fuel gas
mixtures, which can be highly flammable and explosive. The C of F (Compressed Gas and Cryogenic Equipment Operator Qualification)
certification ensures the operator has received proper training to handle these gases safely and effectively.

,Question 4
A Certificate of Fitness Holder must keep his or her certificate
Correct Answer
on their person or otherwise readily available for inspection by any representative of the fire Department
Rationale:
This requirement ensures that in case of an emergency or inspection, the Certificate of Fitness Holder can immediately produce the document
to confirm their qualifications, allowing the fire department to verify their competence and proceed with the necessary actions. By maintaining
the certificate on their person or readily available, the Holder demonstrates a commitment to accountability and compliance with regulations,
which is critical for public safety.
Question 5
The easiest way to extinguish a fire caused by a leak is to
Correct Answer
close the shutoff valve
Rationale:
Closing the shutoff valve is the correct method because it cuts off the fuel source, which in this case is the gas or liquid causing the leak,
thereby preventing the fire from spreading and allowing it to starve for fuel. By shutting off the supply, the fire is deprived of the essential
elements needed to continue burning, making it easier to extinguish.
Question 6
Permits issued by the FDNY are required to conduct the following hot work:
Correct Answer
storing, using or handling oxygen and a flammable gas, storing, using or handling any flammable gas (e.g. LPG or CNG or
acetylene) in excess of
400 SCF. Storing, using or handling any oxidizing gas (e.g. oxygen) in excess of 504 SCF.
Rationale:
These permits are required to ensure the safety of personnel and property from potential fires and explosions, as storing, using, or handling
large quantities of oxygen and flammable gases significantly increases the risk of uncontrolled combustion. The specific quantities of 400 SCF
for flammable gases and 504 SCF for oxidizing gases likely correspond to established safety thresholds beyond which enhanced safety
measures and oversight become necessary to mitigate these risks.
Question 7
For LPG, 400 SCF is
Correct Answer
approximately 47 lbs
Rationale:
The question is referring to the conversion of 400 standard cubic feet (SCF) of Liquefied Petroleum Gas (LPG) to pounds, which requires
knowledge of the specific weight of LPG. The conversion involves using a standard density value for LPG, typically around 37.6 pounds per 100
SCF, but 47 pounds per 100 SCF is a more commonly cited approximation used for calculations.

, Question 8
the number of LPG containers for the storage, use, handling or transportation, requiring a permit
Correct Answer
14.1 oz = 54 cont.
16.4 oz = 46 cont.
20 lbs = 3 cont.
33.5 lbs = 2 cont.
40 lbs = 2 cont.
100 lbs = 1 cont.
Rationale:
This is based on the US Department of Transportation (DOT) regulations for the storage, use, handling, or transportation of LPG (Liquefied
Petroleum Gas) containers, which require a permit when exceeding certain capacity thresholds. The provided table reflects the DOT's weight
and container size thresholds for requiring a permit, correlating specific weights and volumes of LPG to the number of containers needed to
exceed these thresholds.
Question 9
Portable LPG containers that are more than 16.4 oz and CNG containers with a capacity greater than 8.7 SCF
Correct Answer
must NOT 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:
This regulation is aimed at preventing the accumulation of flammable materials indoors, where they pose a significant risk of explosion or fire,
especially in occupancies with higher concentrations of people, such as residential, educational, and institutional spaces. By restricting the
storage, handling, and use of portable LPG and CNG containers in these areas, the regulation helps minimize the risk of catastrophic accidents
and protect human life.
Question 10
Site-specific permit
Correct Answer
may be a permanent permit or a temporary permit. Permanent permits are valid for 12 months only
Rationale:
A site-specific permit refers to a type of permit that is granted for a specific location and set of circumstances, and its validity duration is a
characteristic that defines its nature. By specifying that it may be either permanent or temporary, and further clarifying that permanent permits
are only valid for 12 months, this statement effectively outlines the key features of a site-specific permit.
Question 11
A city-wide permit is valid
Correct Answer
up to 30 days
Rationale:
The phrase "up to 30 days" implies a time frame within which the permit remains valid, rather than an absolute limit. This means the permit is
considered valid from the start of its issuance until the end of the 30th day, and its validity does not abruptly end after 30 days, but rather
continues until the clock strikes 24 hours on the 30th day.
