WARNING
THE RESPIRATOR MUST BE COMPLETELY
DRY BEFORE AND DURING STORAGE.
MOISTURE IN THE FACEPIECE OR THE
WORKING PARTS OF THE RESPIRATOR,
ESPECIALLY WHEN EXPOSED TO FREEZING
TEMPERATURES, MAY CAUSE FOGGING OF
THE FACEPIECE OR A MALFUNCTION OF
THE RESPIRATOR WHICH COULD RESULT
IN SERIOUS INJURY OR DEATH.
WARNING
U S E O F T H I S R E S P I R A T O R I N
TEMPERATURES AT OR BELOW FREEZING,
32° F / 0° C, WITHOUT FOLLOWING THE LOW
TEMPERATURE OPERATION INSTRUCTIONS
MAY RESULT IN OBSCURED VISION DUE TO
FOGGING AND/OR PARTIAL OR COMPLETE
BLOCKAGE OF THE AIRFLOW. IF THIS
SHOULD OCCUR, THE AIR SUPPLY MAY BE
PARTIALLY OR COMPLETELY CUT OFF AND/
OR IT MAY BE DIFFICULT OR IMPOSSIBLE
TO SEE THROUGH THE FACEPIECE LENS
WHICH COULD RESULT IN SERIOUS INJURY
OR DEATH.
LOW TEMPERATURE OPERATION
The respirator is NIOSH approved for use in temperatures to –25 °F
/ –32 °C. For temperatures below 32 °F / 0 °C, approval requires use
of a Nose cup Assembly.
Respirators intended for routine use and respirators not routinely
used but kept for emergency use should be located in areas where
the temperature is maintained above freezing (32 °F / 0 °C). Where
it is expected that the respirator will be used in ambient temperatures
near or below freezing, the respirator shall be equipped with a Nose
cup Assembly to reduce the formation of vision impairing mist or ice
on the interior of the facepiece vision area. A Nose cup Assembly
may be added to the SCOTT-O-VISTA full facepieces.
If a respirator may be unavoidably kept at a temperature below freez-
ing before the next use, special care
MUST
be exercised to be certain
that all components of the respirator are T
HOROUGHLY DRIED
af-
ter cleaning and before storage. Whenever use of the respirator is
anticipated in areas at or below freezing, the facepiece, regulator,
and connection hoses MUST be protected against exposure to water
during storage.
If a respirator must be kept at a temperature below freezing and it is
not possible to bring it to room temperature before it is used, do not
exhale into the facepiece until the facepiece is completely donned
and properly fitted against the face.
