Warnings and Cautions
A. Signal
Words
The following signal words, as defined by ANSI Z535.4-1998, are used in the ToxiPro
Operator’s Guide.
indicates an imminently hazardous situation which, if not avoided,
will result in death or serious injury.
indicates a potentially hazardous situation which, if not avoided,
could result in death or serious injury.
indicates a potentially hazardous situation, which if not avoided, may
result in moderate or minor injury.
CAUTION
used without the safety alert symbol indicates a potentially hazardous
situation which, if not avoided, may result in property damage.
B. Warnings
1.
ToxiPro personal, portable gas detectors have been designed for
the detection of either oxygen deficiencies or specific toxic gas accumulations. An
alarm condition indicates the presence of a potentially life-threatening hazard and
should be taken very seriously.
2.
In the event of an alarm condition it is important to follow
established procedures. The safest course of action is to immediately leave the
affected area, and to return only after further testing determines that the area is
once again safe for entry. Failure to immediately leave the area may result in
serious injury or death.
3.
Use only Duracell Ultra #CR2, Energizer #1CR2 (EL1CR2), Sanyo
#CR2 or Panasonic #CR2 in the ToxiPro.
4.
The accuracy of ToxiPro instruments equipped with toxic gas
sensors should be checked periodically with known concentration calibration gas.
Failure to check accuracy can lead to inaccurate and potentially dangerous
readings. The ToxiPro O
2
should be periodically calibrated in fresh air.
5.
A sensor that cannot be calibrated or is found to be out of
tolerance must be replaced immediately. An instrument equipped with a toxic gas
sensor that fails calibration may not be used until testing with known concentration
test gas determines that accuracy has been restored, and the instrument is once
again fit for use. Instruments equipped with an oxygen sensor that fail calibration
may not be used until testing with fresh air determines that accuracy has been
restored and the instrument is once again fit for use.
6.
Do not reset the calibration gas concentration setpoints in the
ToxiPro unless the concentrations of your calibration gas differ from the
concentrations of the calibration gas that is normally supplied by Sperian
Instrumentation for use in calibrating the ToxiPro.
7.
Use of non-standard calibration gas and/or calibration kit
components when calibrating the ToxiPro can lead to dangerously inaccurate
readings and may void the standard Sperian Instrumentation warranty.
Sperian Instrumentation offers calibration kits and long-lasting cylinders of test gas
specifically developed for easy calibration. Customers are strongly urged to use
only Sperian Instrumentation calibration materials when calibrating the ToxiPro.
8.
Substitution of components may impair intrinsic safety.
9.
For safety reasons the ToxiPro must be operated by qualified
personnel only. Read, understand and follow the directions set forth in this
reference manual before operating the ToxiPro.
10.
The ToxiPro has been tested for intrinsic safety in Explosive
Gas/AIR (max. 21.0% O
2
).
