Let's audit a certain style of subterranean residential-industrial facility, hazard by hazard, because it manages to violate three different subparts before breakfast.
The door. At least two exit routes must be available in a workplace to permit prompt evacuation, located as far away as practical from each other so a blocked route doesn't trap everyone (29 CFR 1910.36(b)(1)). One immense gear-shaped door is one exit route, however dramatic its opening sequence. Worse: employees must be able to open an exit route door from the inside at all times without keys, tools, or special knowledge (29 CFR 1910.36(d)(1)). A door operable only from a management console is the textbook opposite — 'ask the Overseer' is special knowledge with extra steps.
The radiation work. The ionizing radiation standard sets hard exposure limits in rems per calendar quarter (29 CFR 1910.1096(b)) and requires the employer to supply personnel monitoring equipment — film badges, pocket dosimeters — and require its use, including by each employee who enters a high radiation area (29 CFR 1910.1096(d)). The powered suit is welcome, but PPE is selected through a documented hazard assessment (29 CFR 1910.132(d), which governs the helmet, eye, hand, and foot protection it bundles) — and no suit substitutes for monitoring, posting, and dose limits. If nobody's reading a dosimeter, the suit is a costume with lumbar support.
The experiments. Here's the sleeper provision: every employee has a right of access to their own exposure and medical records, on purpose, because access improves detection, treatment, and prevention of occupational disease (29 CFR 1910.1020(a)). A workplace study your workforce cannot see their own records from is a 1910.1020 problem before anyone even reaches the human-subjects laws that other agencies enforce. The pattern for the whole facility: engineering marvels, paperwork felonies. Two exits, worn dosimeters, open records — the future is optional; Subpart E is not.
