1.3 Safety and Precautionary Measures to be Adopted
- The device described in this manual must be installed, operated and maintained
in strict accordance with their labels, cautions, instructions, and within the limi-
tations stated.
- The device is designed to detect gases or vapours in air.
- If a device with a combustible sensor is exposed to vibrations, calibration shall
be done in sufficient short intervals until it is verified that the device is not affect-
ed by the vibration stress.
- Do not mount the sensing head in direct sunlight as this could cause overheat-
ing of the sensor.
- The device must be installed with the sensor inlet pointing downwards to avoid
clogging of the gas inlet by particles or liquids.
- Electrochemical sensors are sealed units which contain a corrosive electrolyte.
Should a sensor develop leakage, it must be immediately removed from service
and disposed of properly. Caution must be exercised so that the electrolyte
does not contact skin, clothing or circuitry otherwise personal injury [burns] and/
or equipment damage may result.
- 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 inspec-
tion of the system.
- As with all devices of these types, high levels of, or long exposure to, certain
compounds in the tested atmosphere could contaminate the sensor. In atmos-
pheres where the device may be exposed to such materials, calibration must be
performed frequently to ensure that the operation is dependable and display in-
dications are accurate.
- The device must not be painted. If painting is done in an area where a device is
located, care must be exercised to ensure that paint is not deposited on the sin-
tered metal flashback arrestor in the gas sensor inlet, if so equipped. Such paint
deposits would interfere with the gas diffusion process.
- Use only genuine MSA replacement parts when performing any maintenance
procedures provided in this manual. Failure to do so may seriously impair instru-
ment performance. Repair or alteration of the device, beyond the scope of these
Attention!
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 instrument, be guaranteed.
