The problem here is with your use of the phrase "industry research". Writing codes and manuals isn't actually research.
Research is research: if it is good research, it counts and definitely carries weight in academia. Research is evaluated by its merit (e.g., intellectual depth, correctness, importance) and its impact (how has it changed practice? how has it changed the course of research done by other researchers?). The names or affiliations of who did the research is irrelevant. It doesn't matter whether the work was done in a university or in a company. It doesn't matter whether the affiliation on the title is a university or a company. What matters is the content of the paper.
If it's good research, it carries weight with academia. It also carries weight with industry research labs.
However, writing health and safety manuals is not research. You shouldn't call it "industry research". You should call it "writing health and safety manuals". And if it's not research, it doesn't count towards your research record and doesn't carry weight.
A good indicator of research is that it is (a) novel, and (b) published in a highly regarded, (c) peer-reviewed forum.
(The question gets more interesting if we are talking about people who do novel, scientific research that could have been published in a peer-reviewed forum, but isn't, because the company wants to keep the results secret. This kind of research is harder for academics to evaluate, and thus might not carry as much weight with academia, because it isn't published. In that case, it's not that the research was performed in industry so much as that the research was never published. In any case, it sounds like that's relevant to you, based upon what you've told us here. Writing health and safety manuals is most likely not something that could have been published in a peer-reviewed conference or journal.)
