Be sure the work area is adequately ventilated before opening any gas
valves. Drain the regulator of gas and release the regulator adjusting
screw before SLOWLY opening the cylinder valves. ALWAYS stand
away from the direction of force when opening cylinder valves.

Install pressure reducing regulators in accordance with

ANSI/AWS Z49.1

.

Use only the appropriate regulator for each gas cylinder:

USE ONLY

ACETYLENE REGULATORS ON ACETYLENE TANKS OR
MANIFOLD SYSTEMS.

Always use the correct size wrench to connect

the regulator to the cylinder valve outlet;

NEVER

force or overtighten a

connection.

NEVER

use oil or grease on a regulator.

1.4.2 Flow

Meters

Install and use flow meters in accordance with

ANSI/AWS Z49.1

. Avoid

unsafe operating conditions and ensure proper flame balance by installing
backflow prevention devices in conjunction with the flow meters. Place a
protective shield on flow meters with glass tubes.

Install and use hose and hose connections according to

ANSI/AWS Z49.1

and the Specification for Rubber Welding Hose

published by the

Rubber Manufacturer’s Association and the CGA. Handle hoses carefully
to avoid damage. Use hoses only in the applications for which they are
designed. Blow out hoses to remove any dust. Avoid any ignition sources.

Turn regulator adjusting screws slowly to prevent surges that may crack or
burst flow meter tubes. Overtightening can collapse the nipple nose, so

NEVER OVERTIGHTEN

the connecting nuts on pressure reducing

regulators and flow meters. If a fitting does not seal without undue force,
replace it.

NEVER

use a flame to check for gas leaks. Use soapy water to check all

hose connections for leaks. Soapy water provides a safer, more sensitive
test.

If any connections leak, depressurize, open the connection, clean the
sealing surfaces and threads, re-assemble, pressurize, and test for leaks. If
a leak persists, depressurize the system.
