Compressed gas cylinders should be stored in an area that is?

The proper storage of compressed gas cylinders is crucial for safety, and the most appropriate option is to keep them free from ignition sources. This is because the gases contained within these cylinders, although classified as non-flammable, can still pose significant risks if exposed to heat or sparks. Such exposure can lead to increased pressures and potential ruptures, resulting in dangerous incidents.

In addition, storing cylinders in an area without ignition sources minimizes the risks of accidents and ensures a safer environment for personnel and nearby equipment. Proper ventilation is also important, but mainly for avoiding the accumulation of gases; therefore, keeping the area free from any potential ignition source is a more critical safety measure.

Other options suggest conditions that are unsafe. Poor ventilation could allow harmful gases to accumulate, while storing cylinders directly under heating units can expose them to dangerous temperatures. Keeping them open to the elements could expose them to unpredictable weather conditions, further increasing risks of damage or accidents.
