involved, in addition to some details regarding its application.
GENERAL SAFETY PRACTICES
Specific procedures for the safe use of this equipment are listed below.
1. Any relief devices protect only the regulator and are not intended to protect any
other equipment. Be sure that any downstream equipment is also protected by relief
device(s) if such equipment can not withstand full cylinder pressure.
2. Never use the regulator for gases other than labeled. It is designed to withstand
3000 PSIG maximum inlet pressure.
3. All connections to the regulator must be clean. Remove dirt or other foreign matter
from the regulator and external connections with a clean lint free cloth. Be sure to
use a new gasket for each installation when a gasket is used.
4. Never pressurize a regulator that has loose or damaged parts or is in questionable
condition. Never loosen a connection or attempt to remove a part until gas pressure
has been relieved. Under pressure, gas can dangerously propel a loose part.
5. Before transporting a cylinder that is not secured on a cart suitable for such
transport, remove the regulator and recap the cylinder.
6. Stand on one side of outlet of cylinder valve or regulator when opening valve.
7. Handle cylinder with care. Chain or otherwise secure cylinders to a permanent
fixture. Take care when moving. To transport cylinders (except when in cylinder
carts), remove regulators and replace with valve cap. Never use any cylinder in
other than an upright position.
8. Use “good housekeeping” in work areas. Keep sparks and flame away from
combustibles.
9. Do not oil or grease equipment. The equipment does not require lubrication. Oil
or grease is easily ignited and burns violently in the presence of pure oxygen or
oxidizing gases.
10. “Crack” cylinder valve before installing regulator. Open valve slightly and then
close. This will clear valve of dust or dirt which may be carried downstream to the
regulator where it could cause damage or be a fire hazard. Do not discharge flow
of gas at any person or flammable material.
11. Be sure all connections are tight. Don’t force connections. Never test for leaks with
a flame. Use a soapy water solution to check for leaks.
12. Use only recommended pressure settings. Improper pressures are wasteful.
Extreme pressure build up in regulators is a warning that they should be taken out
of service and repaired.
13. Do not work with damaged or leaking equipment. Use soapy water when checking
for leaks. Do not use frayed or damaged hose.
14. Handle equipment with care. Its continued good service and your safety depend
upon it.
15. Keep work area well ventilated. Flammable materials burn violently in an oxygen
atmosphere. Flames and glowing materials such as in tobacco smoking must be
avoided.
16. When working with acetylene, never use at pressures over 15 PSIG (Pounds Per
Square Inch Gauge).
17. DO NOT FORCE connectors and threads. The differences are intentional for the
various gases.
