b) SAFETY INFORMATION FOR MEDICAL GAS CYLINDERS
1) The warnings on the previous page relating to the use of oxygen are particularly relevant to gas
cylinders and cylinder pressure regulators.
2) All personnel handling medical gas cylinders should have adequate knowledge of the
properties of the gas, precautions to be taken and the correct operation of the equipment.
3) Check the cylinder for the name of the gas and the colour code to ensure that the correct
cylinder is being used.
4) Before using a cylinder check it and its valve are in good condition. If there appears to be any
damage do not use it.
5) All cylinders are fitted with a colour-coded ring on the valve stem showing when it is due for
inspection or test. Check that the cylinder is within date. If not do not use it.
6) Completely remove the plastic seal from the valve. Open the valve momentarily to blow any
contamination out of the valve outlet. Ensure that the outlet is not directed towards any person.
7) Ensure that the connecting faces on the cylinder and the regulator or fitting are clean and free
from scoring or damage.
8) The regulator or fitting can now be attached, using only a reasonable amount of effort to
tighten the connection. Never use a hammer or lever.
9) Always open the cylinder slowly.
10) Always close the cylinder fully before disconnecting a cylinder and fit a cap or tape to the
cylinder valve outlet to keep it clean.
