Flammable Gas Containers
Edit Save
What is combustible waste? Any substance or item that presents a fire hazard
and has no economic value in connection with the
use or occupancy of premises.
Define compressed gas. A material that is a gas at 68°F or less at 14.7 psia of
pressure and has a boiling point of 68°F or less at
that pressure.
What are the classifications of 1. Non-liquefied compressed gases, 2. Liquefied
compressed gases? compressed gases, 3. Compressed gases in
solution, 4. Compressed gas mixtures.
What is a compressed gas A pressure container designed to hold compressed
container? gases at pressures greater than 1 atmosphere at
68°F.
What is a compressed gas system? An assembly of components designed to contain,
distribute, or transport compressed gases.
What is a containment system? A gas-tight recovery system that stops or controls
the escape of gas from a leaking compressed gas
container.
, Define containment vessel. A gas-tight vessel that confines a leaking
compressed gas container and the gas escaping
from it.
What causes an explosion? The sudden violent expansion of gases due to
chemical, physical, or atomic changes.
What is an excess flow valve? A valve designed to shut off the flow of gas if its
predetermined flow is exceeded.
Define exhausted enclosure. A device that captures and exhausts fumes, mist,
vapors, and gases generated at a workstation.
What is a fire extinguishing system? A system of devices and equipment that detects a
fire and discharges an approved fire extinguishing
agent.
What is a flammable gas? A gas at 68°F or less that is ignitable at 14.7 psia
when mixed with air in a specific concentration.
Define flammable limits. The concentration range of gaseous fuels and air
that will burn when an ignition source is present.
What is a gas cabinet? A fully enclosed, noncombustible enclosure for
storing compressed gas containers.
What is a gas room? A separately ventilated, fully enclosed room for
storing or using compressed gases and associated
equipment.
What does general supervision Supervision by a certificate holder who is not
entail? required to be present on the premises at all times.
