Signal Words
The following signal words, as defined by ANSI Z535.4-1998, are used in the Cannonball3 Reference
Manual.
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 Cannonball3 personal, portable gas detector has been designed for the detection of
dangerous atmospheric conditions. An alarm condition indicates the presence of a potentially life-threatening
hazard and should be taken very seriously. Failure to immediately leave the area during an alarm condition may
result in serious injury or death.
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 during an alarm condition may result in
serious injury or death.
3.
Use only Energizer E95 or EN95, Duracell MN1300, or Duracell PC1300, 1.5V D cell Alkaline
batteries in the Cannonball3. Substitution of batteries may impair intrinsic safety.
4.
The accuracy of the Cannonball3 should be checked periodically with known concentration
calibration gas. Failure to check accuracy can lead to inaccurate and potentially dangerous readings.
5.
The accuracy of the Cannonball3 should be checked immediately following any known exposure
to contaminants by testing with known concentration test gas before further use. Failure to check accuracy can
lead to inaccurate and potentially dangerous readings.
6.
A sensor that cannot be calibrated or is found to be out of tolerance should be replaced
immediately. An instrument 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.
7.
Do not reset the calibration gas concentration unless you are using a calibration gas
concentration that differs from the one that is normally supplied by Sperian Instrumentation for use in calibrating the
Cannonball3. Use of inappropriate calibration gas may lead to in accurate and potentially dangerous readings.
Customers are strongly urged to use only Sperian Instrumentation calibration materials when calibrating the
Cannonball3. Use of non-standard calibration gas and/or calibration kit components can lead to dangerously
inaccurate readings and may void the standard Sperian Instrumentation warranty.
8.
Use of non-standard calibration gas and/or calibration kit components when calibrating the
Cannonball3 can lead to inaccurate and potentially dangerous 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
Cannonball3 calibration. Customers are strongly urged to use only Sperian Instrumentation calibration materials when
calibrating the Cannonball3.
9.
Substitution of components may impair intrinsic safety.
10.
For safety reasons this equipment must be operated and serviced by qualified personnel only.
Read and understand this reference manual before operating or servicing the Cannonball3.
11.
A rapid up-scale reading followed by a declining or erratic reading may indicate a hazardous
combustible gas concentration that exceeds the Cannonball3’s zero to 100 percent LEL detection range for units
without a dilution pump, or zero to approximately 200 percent detection range for units with a dilution pump. 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.
