1-4 Introduction

Expansion Safety

Explosive hazard. Extreme high pressure can rupture
container or plumbing components. Be sure specified
pressure relief devices are present, in the proper location,
and functioning properly.
Important Facts:
• Liquid oxygen at atmospheric pressure expands at a ratio of approximately 860:1
(at 0 psig) when vaporizing into a gas (Figure 1-4). This can occur very rapidly
when exposed to the heat in the atmosphere.
• Ensure that the specified pressure relief devices are present and functioning properly
in any device that will contain liquid oxygen. This includes transfer hose assemblies.

Fire Safety

Concentrated Oxygen. Increased risk of fire.
Do not smoke or keep burning tobacco near this equipment. Death or
injury may occur.
Keep flammable materials away from this equipment. Oils, grease,
including facial creams and petroleum jelly, asphalt, and synthetic
fibers ignite easily and burn rapidly in the presence of concentrated
oxygen. If needed, use only specified oxygen compatible lubricants as
directed.
Keep oxygen equipment away from open flames. Keep Reservoir and
Portable units at least five feet away from equipment such as furnaces,
water heaters, and stoves that may contain open flames.
Keep oxygen equipment away from electrical appliances. Keep
Reservoir and Portable units at least five feet from electrical appliances
that may cause heat or sparks.
