OSHA — when does it apply to you?

OSHA's general-duty clause applies to almost every U.S. employer from day one, but most of the heavier obligations — written programs, recordkeeping forms, posting requirements, and reportable-injury thresholds — kick in once you cross specific headcount thresholds.

A practical rule of thumb: once your company has 15 or more workers in a single calendar year — counting both W-2 employees and 1099 contractors — you should assume full OSHA scope applies and that you'll be expected to maintain written safety programs, Hazard Communication / SDS files, and the recordkeeping forms covered in the Hiring & R&D Safety guide. Below that, you're still on the hook for general-duty safety and for any state-specific rules (state OSHAs are often stricter than federal).

Other compliance thresholds that scale with headcount include FMLA (50+ employees in a 75-mile radius), ADA (15+ employees), ADEA (20+ employees), and various state-specific employer mandates. Stub now — full treatment in the published version of this guide.

Insurance for hazardous-tech labs

If you're working with hydrogen, carbon-dioxide capture, lithium batteries, high-pressure systems, exothermic chemistry, controlled substances, biohazards, or any other class of hazard with real explosion, release, or contamination risk, standard small-business general-liability policies usually don't cover you correctly. Generic insurance agents often don't understand the chemistry or the engineering, mis-rate the risk in either direction, exclude the actual coverage you need, or quote policies that wouldn't pay out if something happened.

You want an agent who works with hard-tech R&D regularly.

Community recommendation
