COMPRESSED GAS CYLINDERS
1
Hazardous gases
Toxic
gases such as CO, NH
3
pose risk via inhalation.
◦
No pressure release valves
Reactive
gases like HCl, NO, and NO
2
make corrosive acids in air.
Metal hydride
gases such as B
2
H
6
are highly toxic and
pyrophoric.
◦
Decompose generating large amounts of H
2
gas, over-pressurizing tanks.
◦
Long term storage problems.
Flammable
gases– H
2
and acetylene
◦
Lighter than air, wide flammable ranges, very low ignition (static spark)
Unstable
gases decompose exothermically– acetylene, NO, NO
2
Chemical asphyxiant (TOXIC)
– HCN, H
2
S, CO
Inert
gases - asphyxiate by displacing oxygen (Ar, N
2
, He, CO
2
)
◦
Have pressure relief valves
2
Gas Cylinder Caps
Always have cylinder cap in place unless in use!
3
Compressed Cylinders
Storage
◦
Secure all cylinders to a wall in designated locations
using a strap.
◦
Labels on cylinder should be visible where stored.
◦
Full, in use, empty tags
◦
Segregate full and empty cylinders and keep
incompatible cylinders >20 ft apart.
◦
eg oxygen gas and other flammable gasses
◦
Do not store cylinders >3 years.
4
Compressed Cylinders
Usage
◦
Get trained on the specifics of using a new regulator
or gas.
◦
Be aware of approved regulator types, required
monitors, PPE and storage when purchasing and
setting up.
◦
(Get help from supplier eg Airgas)
◦
Use the buddy system when changing hazardous gas
cylinders.
◦
Always use a proper carrier or cart with a chain.
◦
Do
not
use Teflon tape or thread sealant on cylinders.

Proper handling and storage of hazardous gases in compressed cylinders are critical to prevent accidents and ensure workplace safety. Toxic, reactive, flammable, and inert gases pose various risks that must be managed effectively. This comprehensive guide covers key safety measures for storage, usage, and handling of compressed cylinders, including identifying different types of gases and implementing necessary precautions to minimize hazards.
