WARNING
Before removing the cover of an explosion-proof Ultima Gas
Monitor, verify that the surrounding area does not contain
a flammable mixture of combustible gas and air, since a
source of ignition is exposed; otherwise, an explosion may
occur if a metal object contacts the circuitry and produces
sparks.
