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	Used as a sterilising agent when cleaning production plant between batches.
Frozen foods	NH₃	Used as a refrigerant. See below
All Foods	Cl₂	User for sterilising area’s
Pet Foods	H₂S	By product of meat rendering
Poultry	CO₂	Used to kill poultry.
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.
