Compressed gas cylinder safety

Compressed gas cylinders present two types of hazards: the chemical hazard
associated with the cylinder contents and the physical hazard from the cylinder
being under pressure. Mishandled cylinders may rupture violently, release their
hazardous contents or become dangerous projectiles.

The following tips are useful as a refresher safety training brief about the
hazards of improperly using or handling compressed gas cylinders.

- Read the cylinder label to identify the contents. The color of the cylinder
is not always an identifying factor.

- Identify the hazards associated with the contents, and take the precautions

- Report unlabeled cylinders to a supervisor so that the supplier can be
contacted to provide the correct information or pick up the cylinder.

- Never expose a cylinder to spark-producing electrical tools, cigarettes or
open flames.

- Cylinders must be secured at all times to prevent falling over (chain,
plastic-coated wire cable, commercial cylinder strap).

- Never attempt to make repairs to cylinders or valves.

- Do not use cylinders as rollers.

- Do not drop cylinders or allow them to bump violently against each other.

- Do not permit cylinders to become part of an electrical circuit.

- Never accept cylinders if they have an expired hydrostatic pressure test

- Do not use grease or oil on oxygen cylinders. Do not use greasy or oily
gloves on them, either.

- Do not use cylinders that are dented, cracked or have other visible damage.

- Always move cylinders with a suitable hand truck.

- Always store cylinders in an upright, secured position and in an adequately
ventilated area.

- Cylinder caps should be secured, straight and hand tight, whether the
cylinder is full or empty.

- Never store a cylinder near an actual or potential source of heat, or where
it will be exposed to weather extremes, or where heavy objects could fall on

- Never store acetylene or flammable gas cylinders on their sides (upright

- Do not store oxygen cylinders within 20 feet of fuel gas cylinders or highly
combustible materials.

- Do not store cylinders containing flammable gases such as hydrogen or
acetylene in close proximity to open flames or other ignition sources.

Empty cylinders should be:

- labeled empty

- stored with valve closed and cylinder cap secured

- stored separately from full cylinders

- returned with all original accessories
