SECTION 4 – OXY-FUEL APPARATUS
4.1 Compressed Gas Cylinders
The Department of Transportation (DOT) approves the design and manufacture of cylinders that
contain gases used for welding and cutting operations.
Cylinders are highly pressurized. Serious accidents may result from
improper handling or misuse. DO NOT drop or knock over a cylinder. DO NOT expose a
cylinder to excessive heat, flames or sparks. DO NOT bang cylinders together. For more
information on proper cylinder handling, consult your local gas supplier.
Figure 1
1. Place cylinders in a vertical position inside the tote. (See Figure 1)
2. When moving cylinders, ensure the cylinder valve is closed.
3. Store empty cylinders away from full cylinders and close the cylinder valves.
4. ALWAYS use a pressure reducing regulator when cylinders are in use.
5. Inspect the cylinder valve for oil, grease and/or damaged parts. DO NOT USE if you
find oil, grease or damage and obtain a replacement from your gas supplier.
6. With it facing away from you, CRACK the cylinder valve to dislodge dust or dirt in an
open and well-ventilated area. If a mist is sprayed by an acetylene cylinder, let it stand
for 15 to 20 minutes and crack again. If this problem persists, DO NOT USE and contact
your gas supplier.
