Workplaces with 10 or fewer employees: If the company had 10 or fewer employees (entire company, not individual locations) at all times during the last calendar year, it is exempt from keeping OSHA 300 Forms. This doesn’t apply if: OSHA or the Bureau of Labor Statistics (BLS) informs the employer in writing that they must keep records. This is referred to as a partial exemption because the reporting requirements of 1904.39 still apply. Establishments in certain industries: If the employer is in an industry group listed in Appendix A of 29 CFR 1904 Subpart B [determined based on the North American Industry Classification System (NAICS)], then it is exempt from keeping OSHA 300 Forms. This doesn’t apply if OSHA or BLS specifically requests recordkeeping or information submission. This is also a partial exemption because the reporting requirements of 1904.39 still apply.
