Compressed Gases

General Requirements:
Employees who work with or near compressed gas cylinders must be aware of hazards associated with those cylinders, and use safe work practices. Compressed gas cylinders are hazardous in that if damaged to the extent of an uncontrolled gas leak, they may act much like a rocket, and travel great distances with great force. Compressed gas cylinders may also contain hazardous materials.

Anyone using a compressed gas cylinder must understand proper operation of the pressure valve, pressure regulator, and proper use and storage of the tanks.

If the compressed gas cylinders are used in conjunction with welding, cutting, or brazing operations, additional safety requirements, described in additional OSHA regulations must be considered. These are addressed in that section of this document.

Regulation:
OSHA 29 CFR 1910.101 Compressed Gases, General Requirements

Frequently-Asked Questions

Q. Why can’t I store the cylinder with the pressure regulator attached?
A. Pressure regulators can be easily damaged, and can be left under pressure (i.e., turned on), creating larger hazards.

Q. Why can’t I use pressure regulators interchangeably?
A. Most are designed to fit only one type of cylinder, and won’t fit others properly, creating a leak hazard; pressure regulators are also designed to work optimally in a specified pressure range appropriate to that cylinder and its contents

Q. How do I know which regulator fits which tank?
A. Your vendor can assist you. Tables of regulators versus compressed gas cylinders can also be found in the catalogs of major vendors.
