Free F60 Torch Operations & Combustibles Questions and Answers 1

Question 1

An F-60 Fire Guard is inspecting gas cylinders before torch operations begin. Which of the following is an unacceptable condition that requires immediate correction?

Accepted Answer

The control valve on an oxygen cylinder has oil and grease on it.

Answer

FDNY regulations strictly prohibit the presence of oil or grease on oxygen containers, valves, regulators, or any related apparatus. Oxygen can react violently with hydrocarbons like oil and grease, creating a significant fire or explosion hazard. Such equipment must not be handled with oily hands or greasy tools.

Question 2

A torch operator needs to test a fuel gas hose for leaks. Which of the following methods is the only one approved by the FDNY for this purpose?

Accepted Answer

Spraying the hose and connections with a soapy water solution.

Answer

Using a flame to test for flammable gas leaks is extremely dangerous and strictly forbidden. The approved and required method is to use a soapy water solution, which will form bubbles at the site of any leak.

Question 3

During a pre-hot work check, a Fire Guard notes that a torch-applied roofing operation is planned for a roof constructed of combustible wood planking. What is the correct action according to FDNY regulations?

Accepted Answer

Prohibit the operation from starting as it is unlawful.

Answer

FDNY rules explicitly state that it is unlawful to conduct torch-applied roof system operations on roofs constructed of combustible materials. This is a prohibited act to prevent severe fire hazards.

Question 4

When torch operations are discontinued for a lunch break lasting one hour or more, what is the required procedure for the gas supply?

Accepted Answer

The torch valve must be closed and the gas supply to the torch must be completely shut off at the cylinders.

Answer

For any discontinuance of hot work for a period of one hour or more, regulations require that the torch valve be closed and the gas supply completely shut off at the source (the cylinders). This prevents accidental gas leaks and potential ignition.

Question 5

Which of the following is a mandatory storage requirement for compressed gas cylinders when they are not in use on a job site?

Accepted Answer

Protected from the direct rays of the sun.

Answer

Compressed gas cylinders not in use must be protected from the sun and other sources of heat. High temperatures can cause the pressure inside the cylinder to rise to dangerous levels. They must also be stored upright and secured.
