Where should refrigerant cylinders be stored to remain safe?
a.Near a boiler to keep them warm
b.Cool, dry, ventilated, upright
c.In direct sunlight on a rooftop
d.Lying down under a stairwell exit
Explanation
Cylinders should be stored in a cool, dry, well-ventilated area away from heat and ignition sources and secured upright so they cannot fall. Storing them near a boiler or in direct sunlight raises pressure dangerously, and blocking an exit path creates an additional hazard. Proper storage reduces the risk of overpressure, valve damage, and leaks.
