Compressed gases

Compressed gases are available in various sized bottles and are supplied at various pressures. It is essential that the correct regulator be used for each gas. NEVER attempt to use an incorrect regulator - they are designed to withstand different conditions. The regulators should undergo a visual inspection every time a cylinder is changed and should be replaced/overhauled EVERY FIVE YEARS. Do not attempt to change a regulator without proper training.

If you should discover a leak on any gas line or cylinder, report it immediately to the Lab Supervisor. If possible isolate the leak by shutting off the cylinder.

All cylinders must be securely clamped both during storage and use. Cylinders should only be moved using a cylinder trolley and by personnel who have attended a manual handling course.
