1.4 Components
1.4.1
The primary components of the monitor are
shown in Figure 1. The instrumentation is enclosed in a
corrosion resistant polypropylene carrying case. The
monitor system includes the instrument case, 10 feet of
1/8" ID x 1/4" OD tubing with fittings, a cylinder of 10 ppm
(parts per million) test gas, calibration connector that
includes the connector valve, tubing, and humidifier.
1.5 Operating
Principles
1.5.1
The CMS monitor samples respiratory air from a
breathing-air source. This enables one monitor to detect
CO and other toxic gases in the entire breathing air
system, not just for one respirator. The air to the
respirator does not actually pass through the monitor.
WARNING
When the CMS is correctly installed and
maintained, it monitors the level of CO and
other oxidizable toxic gases in the air supply.
The instrument is a monitoring device; it DOES
NOT remove or convert CO or any other toxic
gases.
