BLUF: If manufacturer's instructions or chemical SDS, regarding a chemical, are not followed, it's likely an OSHA finding.

Edit: Most people throw away instruction books (or ignore them) and manufacturer's instructions and the books that come to the consumer are generally required to be followed or they have to pay for an IH technician/certified IH to come in and verify there isn't an overexposure. If you follow those, without a survey, it is very unlikely to be an issue (because they are generally extremely conservative).

That said, In my time doing IH surveys, I didn't actually survey one of those specifically, but based on the description above, if there's a smell that bad, it's likely a high VOC exposure and depending on the VOC can be regulated. At a minimum, it's a nuisance exposure and may not be regulated but OSHA would likely still recommend control or depending on the actual chemical, it could even be something as bad an expanded standard chemical.
