What is a common precaution when storing gas cylinders?

Keeping gas cylinders away from flammable materials is a fundamental safety precaution. The reason for this is that while non-flammable gases themselves do not ignite, they are often stored in environments where flammable substances may be present. If a leak occurs or if the gas cylinder is damaged, it could create a situation that increases the risk of fire or explosion, especially if a flammable material is nearby.

Additionally, storing gas cylinders in an area free from flammable materials ensures that any potential hazards are minimized, and it provides a safer working environment. This precaution also allows for safer handling and reduces the chances of an accident, as flame or sparks could come from sources found near flammable materials.

In contrast, other options such as storing in areas with excess sunlight, stacking cylinders on top of each other, or storing in high humidity places can lead to increased risks of cylinder damage, pressure build-up, and general safety hazards that could compromise the integrity of the gas cylinders. Effective storage requires adherence to established safety protocols to maintain safety and compliance with regulations.
