Q&A | Instant Download Pdf
1. What is the primary hazard associated with flammable compressed
gases?
A. Corrosion
B. Fire and explosion

pressure, classifying it as a flammable compressed gas.
3. Under NFPA standards, how should flammable gases be stored?
A. With oxidizers
B. In well-ventilated areas away from ignition sources
C. In underground tanks only
D. Next to heat sources
Proper storage prevents gas accumulation and reduces the likelihood
of ignition.
4. What is the minimum distance flammable gas cylinders must be kept
from sources of ignition?
A. 5 feet
B. 20 feet
C. 1 foot
D. 50 feet
Maintaining this separation reduces the risk of heat or sparks
igniting released gas.
