Electrochemical sensors (

Carbon monoxide) 

 
Electrochemical sensors contain toxic compounds. Under normal conditions the sensor will 
be safely sealed. To prevent leakage, the unit must not be exposed to temperatures 
outside the specified range, or be exposed to organic vapours, which may cause physical 
damage to the body of the sensor. The unit must not be stored in areas containing organic 
solvents or in flammable liquid stores. 
 
When the life of the sensor has expired, or it is leaking or otherwise damaged it must be 
disposed of safely in accordance with local regulations. 
 
Carbon monoxide cell contains an acidic electrolyte (sulphuric acid).  In the event of an 
accident, use the following first aid procedures.

manufacturing error, physical damage, etc. then wear protective gloves when cleaning any 
spills. Should electrolyte contact skin then the affected area should be washed thoroughly 
with copious water and medical advice sought if there has been any contact with the eyes 
or mouth. If connected to any electrical equipment, the sensor should be immediately
