Food Industry

The food industry has many uses for gas detection.  Multi-channel portables will be used for confined space work.  These again will typically be the responsibility of the safety manager.  In addition they may have specific requirements for individual gas monitors (SGT-P type) for a range of toxic gases.  Typical examples are;


Food manufactured

Gas

Application

Jam, preserves, sauces

SO2

CO2

Processed Foods

O2

Liquid nitrogen often used in the process for freezing and fast chilling.  Leaks can deplete the oxygen level.

 

Fixed systems could be used for all the above applications and usually are.  The main thing to remember in the food industry is that any piece of equipment that is likely to be hosed down regularly and therefore care is needed in siting fixed heads and particularly panels.
