Described in Step 6
NOTICE
The casters on this cart have conductive
rubber tires and a special Dow No. 41
lubricant was used to lubricate the
swivel bearings to insure conductivity.
The casters were tested by the caster
manufacturer in accordance with
NFPA56A and were certifi ed as being
conductive when shipped.
To maintain conductivity, note the
following:
1. Petroleum base grease is forbidden in
fl ammable anesthetizing locations.
2. Use of excessive amounts of grease
must be avoided. Grease accumulated
on the conductive tires must be
removed.
3. Buildup of fl oor wax, cleaners and
dirt will cause the tires to loose their
conductivity. Any buildup should be
removed immediately.
CONDUCTIVITY TEST
Prior to placing this cart in service, and
at intervals not to exceed one month; the
electrical resistance of the casters must
be measured. The measurement must
be made using a calibrated ohmmeter,
having a nominal open circuit output
voltage of 500 volts direct current, and a
short circuit current of fi ve milliampres
with an effective internal resistance of
100,000 ohms, plus or minus 10,000
ohms (10%). The measurement must be
made in an area where the fl oor is dry.
Place a copper plate under one caster,
and electrically insulate the copper plate
from the fl oor. Place one probe of the
ohmmeter on the copper plate, and the
other probe anywhere on the module. The
ohmmeter must indicate no more than
250,000 ohms. Repeat the above test for
the remaining three casters.
DISCLAIMER
InterMetro Industries Corporation accepts
no responsibility for the conductivity of
the casters on this unit. The casters are
warranted by the manufacturer thereof;
copy of certification of conductivity
by manufacturer will be supplied upon
request.
