INTRINSIC SAFETY
Intrinsically safe equipment is defined as "equipment and wiring which is incapable of releasing sufficient electrical
or thermal energy under normal or abnormal conditions to cause ignition of a specific hazardous atmospheric mixture
in its most easily ignited concentration." (ISA-RP12.6) This is achieved by limiting the amount of power available to
the electrical equipment in the hazardous area to a level below that which will ignite the gases.
In order to have a fire or explosion, fuel, oxygen and a source of ignition must be present. An intrinsically safe system
assumes the fuel and oxygen is present in the atmosphere, but the system is designed so the electrical energy or
thermal energy of a particular instrument loop can never be great enough to cause ignition.
BATTERIES
WARNING:
Batteries must be changed in Non-hazardous area.
Batteries must be of correct approved type.
Batteries must be installed with correct polarity making sure the (+) end of the battery is aligned with (+)
symbol embossed in the battery case.
New batteries must not be mixed with old batteries.
Batteries must not be mixed with batteries of other models or manufacturers.
Batteries must not be installed with polarity reversed where one cell could charge another cell.
