1.3 Safety and Precautionary Measures to be Adopted
WARNING!
The following safety instructions must be observed implicitly. Only in this way can the safety and health
of the individual operators, and the correct functioning of the device, be guaranteed.
• The device described in this manual must be installed, operated and maintained in strict accor-
dance with the labels, cautions, instructions, and within the limitations stated.
• Protect the device from extreme vibration.
• Do not mount the device in direct sunlight, since this may cause it to overheat. A stainless steel
sunshield is available for the PrimaX IR Gas Monitor to protect it from extreme environments.
• The only absolute method to ensure proper overall operation of the device is to check it with a
known concentration of the gas for which it has been calibrated. Consequently, calibration checks
must be included as part of the routine inspection of the system. The device is labeled with the
type and value of the factory calibration gas.
• Use only genuine MSA replacement parts when performing any maintenance procedures
provided in this manual. Failure to do so may seriously impair device performance. Repair or alter-
ation of the device, beyond the scope of these maintenance instructions or by anyone other than
an authorized MSA service provider, could cause the product to fail to perform as designed.
• There are no field-repairable internal components for this device. Return to MSA for warranty
replacement per the Warranty section.
• This device does not detect the presence of hydrogen gas and must never be used to monitor for
hydrogen gas.
• The standard device must never be used in atmospheres containing acetylene gas. Contact MSA
regarding available acetylene sensors.
• Calibrate frequently if used in atmospheres exposed to high levels of solvents or dust. See chap-
ters 4 and 5 for calibration and cleaning procedures.
• Do not paint the device. If painting is done in an area where the device is located, exercise caution
to ensure paint is not deposited on the device. Such paint deposits could interfere with the device
operation. Solvents in the paint may also cause an alarm condition to occur.
• The device is designed for applications in hazardous areas under environmental conditions
defined in the Specifications section of this manual.
• The response time of the device can be increased by significant dust deposits. Checks for dust
deposits must be done at regular intervals.
• The PrimaX IR sensor will detect other hydrocarbon gases than the target gas.
• Oxygen enriched atmospheres greater than 21 Vol % can affect the measurement and the elec-
trical safety of the Gas Monitor.
