904 Oil and Gas Well Inspection
Skip to main content

Compressed Gas

The purpose of this inspection is to ensure that gas cylinders are stored properly and do not present a hazard to employees. For more information see: 29CFR1910.101 – 104, DHHS (NIOSH) Publication Number 2004-101, and local emergency response agencies.

Storage Locations

List each area where compressed gas cylinders (bottles) are stored. Enclosed areas used for the storage of compressed gas cylinders should be ventilated to prevent an accumulation of gas. Gas cylinders should be stored upright and immobilized by chains or other means to prevent them from being knocked over. All stored compressed gas cylinders, including empty cylinders, must have the valves closed and the caps installed. Compressed gas cylinders should not be exposed to heat.

In use Cylinders

Dedicated racks should be available to hold nitrogen bottles that are used for backup on accumulator systems. Portable compressed gas cylinder racks for welding and cutting should be in good repair and the cylinders should have protection around the valves should the rack tip over. When moving gas cylinders from one place to another, the gauges should be removed and the caps installed to protect the valve.
