Gas Safety

Compressed gas has a variety of uses from breathing (as in diving), through dispensing of beverages (as in draught beer), fuel for vehicles, laboratory experiments to welding.

Compressed gas cylinders (and disposable cartridges) are a convenient way to transport and store gases under pressure - a lot of gas is contained in a small volume. Compressed gas containers are therefore pressure vessels. Mishandling or misuse or overheating (especially if caught in a building fire) could cause the full gas pressure to be suddenly released. In such circumstances, gas containers can become very dangerous projectiles, behaving just as a toy balloon does if it is let go before the end is tied up.

Some gases are harmful to health others are serious fire risks. The larger cylinders are heavy and awkward to handle. Accidents involving gas cylinders can cause serious injury or even death.
