Expert talks safe sensor use

Oxygen depletion sensors should not
be used environments where the
target gas is carbon
dioxide, warns Tim
Holmes, MD of Safety
Gas Detection,
manufacturer, installer
and servicer of gas
monitoring systems.

His assertion is that
that use of oxygen
depletion monitoring
in environments such
as university
laboratories,
pharmaceutical
companies and the
drinks industry is not
sensitive enough for the detection of
carbon dioxide. This means that
levels of carbon dioxide may become
dangerously high before the alarms
are triggered.

Instead, Holmes
recommends infra-red
carbon dioxide
sensors, the cost of
which has plummeted
in recent years.

Safety Gas
Detection provides gas
alarm systems that
monitor the presence
and depletion of a
range of gases
including carbon
monoxide (CO),
carbon dioxide (CO2),
flammable gas, oxygen,
refrigeration gas, and toxic gas.
