Operating the EntryRAE
Confined Space Pre-Entry Test
It is important to always test the atmosphere inside a confined space before
entering. Be aware of any hazardous chemicals you may be bringing into
the space. Remember that many cleaners, paints, adhesives, degreasers
and other modern industrial products (even treated wood) contain volatile
organic compounds that may be hazardous to your health and safety.
Test the atmosphere in the confined space by sampling air at three levels
(top, middle and bottom) in the confined space. Give the instrument time
to sample the gas at each level - the correct sampling time is 60 seconds
plus 1 second for every foot of tubing.
Alarms
If there are any gas
ALARMS
at any level in the confined space, that
space is not safe.
DO NOT ENTER!
Identify the alarm condition and then
start your preventive actions according to your company’s confined space
entry procedures.
No Alarms
If there are no alarms, the confined space may be safe to enter. Disconnect
the tubing before carrying the EntryRAE into the confined space. If
monitoring is to be done by a confined space attendant, they should
continue to monitor while you enter the area. If the monitor alarms and
“BAT” is displayed, the battery needs to be charged: There are 15 minutes
Storage
Always keep the EntryRAE on its charging
cradle in a dry indoor area when it is not in use.
See page c for long-term storage warnings and
procedures.
EntryRAE Usage Overview
After the EntryRAE is warmed up, calibrated, and charged, it is ready for
use to enhance your personal safety.
CAUTION:
HIGH OFF-SCALE READINGS MAY INDICATE AN
EXPLOSIVE CONCENTRATION.
