Playing the devil's advocate what is the risk?
Hi Tony, et al,
Although no specific mention as yet, i presume we are talking about Prerequisite functions.
So what are the Canadian regulations for design prevention of cross-contamination / Food manufacturing? Over to Wow perhaps.
Can cross-contamination defy gravity ? Hmmm.
On the other hand, noting the geographical location, perhaps glass < 2 mm is not considered a significant health risk anyway so maybe a quantitative RA is in order ?. (Wanna bet on a handful for $1 ? ) (I'm not sure if Canada also copies the US adulteration rules ?)
Frankly, IMO a direct linkage from "maintenance" to a (food contact-related) storage area should be avoided in the first place, regardless of whether a direct onward linkage to production exists. Regulation justifiable ?
So as per my present knowledge (or in some respects, lack of), i guess my answer to the OP is yes with exception of "offices" (assuming conformance to above-mentioned caveat[s]). the lunchroom scenario is so far unknown.
