5.2 Areas of use
The PGD3-IR Portable Gas Detector is intended to be used for personnel protection and is specifically designed and certified to be
safe in the following areas: -
i) Confined spaces
that is, areas where normal atmospheric ventilation is not available, e.g. sewers, tunnels, ducts, storage vessels etc.
ii) Hazardous areas
classified as Class 1, Div 1, Groups A, B, C, D.
5.3 Methods of use
The PGD3-IR can be utilised for: -
Personal protection
With the instrument worn on the person as close to the breathing area as possible and switched on at all times.
5.4 Basic Precautions
The following basic precautions should be observed in order to ensure that the instrument provides the protection for which it is
intended: -
a)
Ensure that the instrument is of the correct type for the gases to be detected.
b) Before use, check that the instrument is within its calibration period - see Section 6.6.
c) Before use, check that the instrument is not physically damaged and that all covers are intact.
d) Before use, establish that the instrument has been charged sufficiently.
e) When in use, ensure that the gas sensor inlets are not obstructed - the instrument must not be used whist in a pocket, bag or
other confined container.
f) When lowering the instrument into for example, a manhole, ensure that it is not lowered into fluids.
g) Use the instrument in its rubber boot at all times.
