Care and maintenance
Training (continued)
Before entering a potentially hazardous situation, turn on and test the
thermal imager to confirm it is operating properly. Failure to confirm
the thermal imager is operating properly may place the user at higher
risk in dangerous situations which could result in serious injury or
death.
Beware of misconceptions about thermal imagers. Thermal imagers
only show temperature differences between objects and not an optical
image of the objects. The greater the temperature
difference, the more distinct the thermal image. Experience and
training are required to correctly interpret the thermal image.
These are some other circumstances which could result in
misinterpretation:
• The thermal imager cannot see through walls. A source of heat
behind a wall will not be evident if it does not heat the wall itself
• The heat from some high temperature objects or sources of high
heat may be blocked, obscured, or made less distinct in the
thermal image display by any of the following:
• Water mist, spray, or highly saturated fog
• Some chemical substances in a concentrated cloud or vapor
• Extremely dense smoke
• Heated smoke or a layer of heated gases
• If a concrete floor and a hole in that floor have the same
temperature, there will be no apparent difference in the thermal
image display to indicate the presence of the hole
