Safety Facts<br />
Fire Safety<br />
The possibility of fire exists when the combination of a fuel, source of ignition, and oxygen is<br />
present, reference Figure 1. High concentrations of oxygen (air is approximately 21% oxygen)<br />
greatly enhance the possibility of combustion.<br />
• Obtain all replacement parts for medical oxygen equipment from the manufacturer.<br />
• Before servicing, clean all tools that come into contact with the oxygen system.<br />
• Use only recommended oxygen compatible cleaning and leak detection products.<br />
• Keep the EasyMate <strong>Reservoir</strong> upright at all times. Secure liquid oxygen equipment when<br />
transporting to prevent accidental tip over and spillage.<br />
• If a liquid oxygen spill occurs indoors, open doors and windows to ventilate the area. Avoid<br />
sources of ignition and do not walk on or roll equipment over the affected area.<br />
• Any clothing or porous material that is splashed with liquid oxygen or otherwise absorbs<br />
high concentrations of oxygen should be removed and aired for at least one hour away from<br />
any source of ignition.<br />
OXYGEN SOURCE<br />
Approximately 16% required<br />
for combustion.<br />
Normal air contains 21% oxygen.<br />
Some fuel materials contain<br />
sufficient oxygen within their<br />
make-up to support burning.<br />

Explosion Safety<br />
• <strong>Liquid</strong> oxygen at atmospheric pressure expands at a ratio of approximately 860:1 (at 0 psig)<br />
when vaporizing into a gas, reference Figure 2. This can occur very rapidly when exposed to<br />
the heat in the atmosphere.<br />
• Ensure that the specified pressure relief devices are present and functioning properly in any<br />
device that will contain liquid oxygen. This includes transfer hose assemblies.<br />
