Iow Temperature Operation; Use Of The Ric Uac In Iow Temperature - Scott 2.2 Operating & Maintenance Instructions

lOW TEMPERATURE OPERATION
Respirators intended for routine use and respirators not routinely used but
kept for emergency use shall be located in areas where the temperature
is maintained above freezing (32° F / 0° C).
If a respirator may be unavoidably kept at a temperature below freezing
before the next use, special care MUST be exercised to be certain that
all components of the respirator are THOROUGHly DRIED after clean-
ing and before storage.
If a respirator has been unavoidably kept at a temperature below freez-
ing and it is not possible to bring it to room temperature before use, DO
NOT exhale into the facepiece until the facepiece is completely donned
and the nose cup is properly in place against the face. This will prevent
fogging of the cold facepiece.
If, after using the respirator, the facepiece is doffed in a safe breathing
area which is at temperatures near or below freezing, we recommend
placing the facepiece with regulator connected under outerwear to keep
it warm next to the body in case respirator reuse is required. AT A MINI-
MUM, remove the regulator and place it under outerwear to keep it warm.
Whenever the respirator is in place but not in use ("STANDBY" CONDI-
TION) in areas at or below freezing, the facepiece and regulator MUST
be protected against exposure to water.
USE OF THE RIC UAC IN lOW TEMPERATURE
Use the protective cap to keep the high pressure air inlet of the RIC UAC
coupling covered and dry at all times. Water on the inlet may freeze pre-
venting connection to the RIC UAC filling hose assembly or preventing
removal of the RIC UAC filling hose assembly once connected.
If the RIC UAC filling hose assembly is used to fill a respirator cylinder in
temperatures less than 32° F / 0° C and the full respirator is then moved
indoors to warmer temperatures, the pressure in the cylinder MUST BE
CHECKED FOR EXCESS PRESSURE within two hours after the respirator
is moved indoors. If the pressure gauge on the cylinder is reading above
"full", excess pressure must be removed from the cylinders by releasing
air from the respirator until the pointer of the gauge is reading "full".

WARNING
IF A RESPIRATOR CylINDER IS FIllED IN
TEMPERATURES lESS THAN 32° F / 0° C AND
THE FUll RESPIRATOR IS THEN MOVED
INDOORS TO WARMER TEMPERATURES,
THE PRESSURE IN THE CylINDER MUST BE
