How it works

An unofficial set of 79 questions for the G-60, Torch Use of Flammable Gases. All of them come from the study booklet the New York City Fire Department revised in January 2026, read on October 5, 2026, and every explanation points to its section.

Six topics from the booklet

The Start from menu drills one part at a time: the exam and the certificate, where torch work and gas are barred, torch equipment and its use, handling and storing containers, acetylene, LPG and CNG, leaks and warning signs.

Exam mode follows the notice

Switch to exam mode for a timed round shaped like the notice: 35 questions, 53 minutes, 70 percent to pass. Only the shape is borrowed; the wording of every question is this site's.

  • Two pressures to keep apart: oxygen is stored at up to 2200 psi, and acetylene is never worked above 15 psi (sections 2.1.2 and 3.2).
  • The booklet gives one answer for ice on a container or gas heard at its relief valve: call 911 immediately.
  • An empty container is replaced; the booklet calls refilling containers illegal in the city (section 3.1.1).

Questions and answers

How long is the G-60 exam?

It has 35 multiple-choice questions and a 53-minute limit, and 70 percent or better passes, according to the exam information in the January 2026 booklet. A later revision could change those figures, so the department's posted booklet has the last word.

Are these the real G-60 exam questions?

No. This site has never seen the department's exam and is not affiliated with the New York City Fire Department. Each was written for this page from the booklet's facts; its sample questions were left alone. No certificate holder has reviewed them yet.

Who has to hold a G-60?

The booklet gives the G-60 to the person who uses a torch with oxygen and a flammable gas, and says any hot work operation must be carried out in person by a certificate of fitness holder.

Is the G-60 the same as the F-60?

No. The F-60 belongs to the fire guard who keeps the fire watch during torch work. The G-60 belongs to the person operating the torch. Each has its own study booklet and its own exam.
