Yes, Hank - thank you.
and that is exactly what happens, a production employee can not find a cleaner and goes into an office and gets "something" that is not food safe and uses that, happens a lot.
The OP is hopefully solvable by -
(a) requiring QA approval to use any unlisted Chemical in a Production area .
(b) implementation of GMP./Food Defense/Risk Assessment, for example, it would be rather nonsensical IMO to use a highly fragranced cleaner/sanitiser in a toilet in proximity to the Production Area but might be irrelevant for a distant, unconnectable Office ?? Or a worst-case scenario might be justifiably implemented ??
Unfortunately, human error/blunder is always a potential, non-100%-eliminatable hazard.
PS - ([a] has a different problem if Upper Management are unable to trust QA).
With respect to SQF, I note -
184.108.40.206 The methods and responsibility for the cleaning of the food handling and processing equipment and environment, storage areas, staff amenities and toilet facilities shall be documented and implemented.
220.127.116.11 Detergents and sanitizers shall be suitable for use in a food manufacturing environment, labelled according to regulatory requirements, and purchased in accordance with applicable legislation. The organization shall ensure:
i. The site maintains a list of chemicals approved for use;
ii. An inventory of all chemicals purchased and used shall be maintained;
iii. Detergents and sanitizers are stored as outlined in element 11.6.4;
iv. Safety Data Sheets (SDS) are provided for all detergents
(Section 11.6.4 is also highly detailed)
PPS - Personally, for Production area approved Chemicals, I would add a (v) to above list - Supplier's documentation ideally stating that Chemical is Food Grade or Food Safe but, in the case that these 2 terms are not realistic, minimally stating that Chemical is suitable for use in a Food Manufacturing Environment. (I can also conceive of a possible necessity in some situations for the processor to establish equivalent validatory documentation by himself, eg well-water).
