This makes it popular for use in underground operations and workplaces. Acetylene is an extremely volatile gas which has a high risk of a dangerous chemical reaction called decomposition. Decomposition is a spontaneous reaction that can cause high energy explosions.

To stabilise the gas against decomposition, acetylene is never stored in a pure state. Instead it is mixed with a liquid solvent usually acetone and stored in a special cylinder which contains a porous filler material also known as a porous mass. The liquid acetone is absorbed by the porous filler material which also serves to slow down or halt any decomposition reactions.

It is critical that these specifically designed cylinders are stored and handled with extreme care. According to AS - The storage and handling of gases in cylinders , all gas cylinders must be stored in an upright position and secured with safety chains or other secure restraints. It is especially important for acetylene cylinders to be stored upright to prevent the gas separating from the acetone.

This is so critical cylinders should be allowed to rest for at least for hours if they have been moved about in the workplace or just received from the supplier. Acetylene is so volatile you can expect that ANY leak at all will result in a fire. Because acetylene can ignite from even the smallest amount of static electricity cylinder stores must be located away from any possible ignition sources.

Ensuring your cylinder stores are not exposed to ignition sources including static electricity will require a thorough risk assessment. Your risk assessment may include the following considerations:. Because even rough handling of acetylene cylinders can result in a delayed explosion, it is essential that storage facilities secure them from falling over; being dropped; impacted by forklifts and falling objects; or able to strike one another.

The best place to store the cylinders is in a sturdy gas bottle cage that protects the cylinders from impact. The store must also be clearly marked with compliant warning signs and placards as well as fenced or locked to prevent untrained and unauthorised personnel from accessing the cylinders. Safely storage acetylene and other gas cylinders is a must and adherence to the Australian Standard AS is a critical component of ensuring your compliance with WHS legislation.
