the MSA 2a combustible gas indicator, 
(1

-
originally designed for the mining industry to
 
detect
methane gas in coal mines

-
Soon
, 
industry and the fire service began using CGIs in
various 
scenarios 
(
natural gas leak
ing, presents of the
flammable gases
...);
-
Today, 
e
mergency responders have access to a 
number of
sophisticated instrumentation
