Before attaching the regulator, remove the protective cap from the cylinder.
Stand to one side of the cylinder. Open the cylinder valve slightly for an instant, and
then close it. This "cracking" of the cylinder valve will clean the valve of dust or dirt
which may have accumulated during storage. Dirt can damage critical parts of a regulator,
and may cause a fire or explosion. Before a regulator is removed from a cylinder valve, the valve shall be closed and the gas released from the regulator. An acetylene cylinder valve shall not be opened more than one and one-half turns of the spindle. This permits adequate flow of acetylene and allows ready closing of the valve in an emergency situation. Let’s see how much you have learned. Go to the next page. |
