Warnings and Cautions
A.
Signal Words
The following signal words, as defined by ANSI Z535.4-1998, are used in the Toxi PlusOperator’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.

Warnings
1.
The Toxi Plus personal, portable gas detector has been designed for the
detection of 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.
Hand aspirated remote sampling only provides continuous gas readings as
long as the bulb is being squeezed.
4.
The accuracy of Toxi Plus instruments should be checked periodically with
known concentration calibration gas. Failure to check accuracy can lead to inaccurate and
potentially dangerous readings.
5.
A sensor that cannot be calibrated or is found to be out of tolerance must be
replaced immediately. An instrument equipped with a 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.
6.
Do not reset the calibration gas concentration setpoints in the Toxi Plus
unless the concentration of your calibration gas differs from the concentration of the calibration gas
that is normally supplied by Biosystems for use in calibrating the Toxi Plus.
7.
Use of non-standard calibration gas and/or calibration kit components when
calibrating the Toxi Plus can lead to dangerously inaccurate readings and may void the standard
Biosystems warranty.
Biosystems offers calibration kits and long-lasting cylinders of test gas specifically developed for
easy calibration. Customers are strongly urged to use only Biosystems calibration materials when
calibrating the Toxi Plus
8.
Substitution of components may impair intrinsic safety.
9.
For safety reasons the Toxi Plus must be operated by qualified personnel
only. Read, understand and follow the directions set forth in this reference manual before operating
the Toxi Plus.
10.
The Toxi Plus has been tested for intrinsic safety in Explosive Gas/AIR(21.0%
O2) Only.
