• Which of the following is the primary hazard associated with

flammable gases under pressure above 6 PSI?

a) Electrical shock

b) Fire or explosion

c) Slips and falls

d) Chemical burns

Rationale: Flammable gases under pressure can ignite easily, posing

serious fire and explosion hazards.

2. When storing flammable gases, cylinders should be:

a) Placed in direct sunlight 1 / 4

b) Stored upright and secured

c) Laid on their sides

d) Stored near heat sources

Rationale: Storing cylinders upright and secured prevents tipping and

reduces the risk of leaks or ruptures.

• What is the minimum distance flammable gas cylinders must be kept

from sources of ignition?

• 5 feet
• 20 feet
• 50 feet
• 100 feet

Rationale: Maintaining at least 20 feet from ignition sources reduces the

risk of accidental fire.

• Which color coding typically indicates a flammable gas cylinder?

d) Yellow

Rationale: Red is commonly used to identify flammable gases to ensure

safety awareness.

5. Compressed flammable gases should never be:

a) Transported with proper caps 2 / 4

b) Exposed to flames or sparks

c) Stored in ventilated areas

d) Checked for leaks regularly

Rationale: Exposure to flames or sparks can ignite flammable gases,

causing fires or explosions.

• The purpose of a pressure relief device on a flammable gas cylinder is

to:

a) Increase pressure

b) Prevent over-pressurization

c) Allow free gas release at all times

d) Reduce cylinder weight

Rationale: Pressure relief devices prevent cylinder rupture due to excessive

internal pressure.

• Which of the following is a safe way to transport flammable gas

cylinders?

a) Dragging them on the ground

b) Using a cylinder cart

c) Rolling freely in a vehicle

d) Carrying by the valve

Rationale: Using a proper cart reduces the risk of dropping or damaging

Rationale: Checking for leaks before each use ensures safety and prevents

accidental fires.

• Which of the following gases is considered flammable above 6 PSI?

a) Oxygen

b) Propane

c) Carbon dioxide

d) Nitrogen

Rationale: Propane is a highly flammable gas that is stored under pressure

above 6 PSI.

• In the event of a small leak in a flammable gas cylinder, you

should:

a) Light a match to see the leak

b) Evacuate the area and ventilate

c) Ignore it

d) Tighten the valve with force

Rationale: Evacuating and ventilating prevents accumulation of flammable

vapors that could ignite.
