WARNING
If the 100% LEL alarm condition is reached, you may be in
a life-threatening situation; there is enough gas in the
atmosphere for an explosion to occur. In addition, any rapid
up-scale reading followed by a declining or erratic reading
can also be an indication that there is enough gas for an
explosion. If either of these indications occur, leave and
move away from the contaminated area immediately. Failure
to follow this warning can result in serious personal injury
or death.
•
After moving to a safe, fresh-air environment, reset the alarm by
turning OFF the instrument and turning it ON again.
