Questions with Verified Answers
Air Exhaust - ANSWERSAir being removed from any space or piece of equipment and
conveyed directly to the atmosphere by means of openings or ducts.
Auto- Ignition - ANSWERSIgnition of a substance, such as oily rags and hay, caused by
a localized heat increasing reaction between the oxidant and the fuel and not involving
addition of heat from an outside source.
Compressed Gas - ANSWERSA material or mixture of material that is a gas at 68
degrees F or less at 14.7psia of pressure, has a boiling point of 68 degrees F or less at
14.7psia and can be liquefied, non-liquefied or in solution at that temperature and
pressure, except that gases which have no other health or physical hazard properties
are not considered to be compressed until the pressure in the packaging exceeds
41psia at 68 degrees F.
Types of Compressed Gases - ANSWERS1. Non-liquefied compressed gases- Gases
other than those in solution, that are in a packaging under the charged pressure and are
entirely gaseous at a temperature at 68 degrees F.
2. Liquefied compressed gases- Gases that in a packaging under the charged pressure
are partially liquid at a temperature of 68 degrees F.
3. Compressed Gases in Solution- Non-liquefied gases that are dissolved in a solvent.
4. Compressed Gas Mixtures- A mixture of two or more compressed gases contained in
a single packaging, the hazard properties of which are represented by the properties of
the mixture as a whole.
Compressed Gas Container - ANSWERSA pressure container designed to hold
compressed gases at pressures greater than 1 atmosphere at 68 degrees F.
BE CAREFUL!!
Compressed Gas System - ANSWERSAn assembly of components, such as
containers, reactors, pumps, compressors, and connecting piping and tubing, designed
to contain, distribute or transport compressed gases.
Permits for a Compressed Gas System - ANSWERSNot transferrable and any change
in occupancy, operation, tenancy, or ownership must require a new permit. A permit is
required to compressed gases in excess of exceeding 6psig.
Exception: Outdoor air compressing at other then than a fair or festival.
, Certificate of Fitness - ANSWERSThe storage, handling, in use of flammable gases
compressed to a pressure exceeding 6psi shall be supervised by the G-29 certificate
holder.
Handling and Use: the quantities requiring permits shall be personally supervised by the
G-29 certificate holder.
Storage: the storage of compressed gases in quantities requiring a permit shall be
under the general supervision of the certificate holder.
The certificate of fitness holder are responsible for insuring all fire department
regulations related to the safe using, handling and storage of flamed compressed gases
are obeyed on the premises. The G-29 certificate is valid for 3 years. C of F holders
must maintain their certificates of fitness cards throughout the entire term of their
employment.
G-61 certificate of fitness shall also be attained for individuals interested in using
torches for the manufacture of jewelry.
The storage, handling, compression and use of compressed flammable gases with
pressures of 6psi or less does not require a G-29 certificate of fitness holder on the
premises. It can be revoked if C of F holder fails to fulfill their duties.
Duct System - ANSWERSA continuous passage way for the transmission air that in
addition to ducts, includes duct fittings, dampers plenums, fans, and accessory air
handling equipment, and appliances.
Engineer - ANSWERSA person licensed and registered to practice the profession of
engineering under the education law of the State of New York.
Fuel Gases - ANSWERSFuel gases include: A natural gas, manufactured gas, liquefied
petroleum gas, hydrogen gas and mixtures of these gases.
Flammable Gas - ANSWERSA material which is a gas at 68 degrees F or less at
14.7psia of pressure which:
1. Is ignitable at 14.7psia when in a mixture of 13% or less by volume with air. In
accordance with testing precedures set forth in ASTME681 or
2. Has a flammable range at 14psia with air of at least 12% regardless of the lower limit.
In accordance with testing precedures set forth in ASTME681.
Flammable Liquefied Gas - ANSWERSA liquefied compressed gas which, under a
charged pressure, is partially liquid at a temperature of 68 degrees F and which is a
flammable gas.
