Warning Compressed gas sign is a warning safety sign that warns about compressed gas dangers. Because compressed gas can cause explosions and fires, it must be stored safely, with the storage chamber clearly labelled and maintained at the right temperature. Nitrogen, helium, oxygen, and carbon dioxide are examples of compressed gas cylinders that require a warning sign. They have the potential to explode when heated. This yellow triangle warning safety sign features a compressed gas warning emblem and large black lettering. Our gas compression warning sign is available in a range of sizes and materials, as listed below. Where relevant, our products are designed to comply with UK government requirements, or to follow best practise and conform to ISO 7010.
