What the Data Says About Professional & Technical Services
According to OSHA enforcement records (2010–2026), Professional & Technical Services ranks #11 of 21 industries by average penalty per inspection ($2K). The Professional & Technical Services sector (NAICS 54) contains 3,597 employers with OSHA enforcement records, generating 2,095 inspections and 4,169 documented violations across the industry. That works out to 1.99 violations per inspection and roughly 0.6 inspections per employer. Cumulative OSHA penalties against this sector total $4.9M.
The listing order matches most-dangerous industries: average penalty per inspection, highest first. The inspection-weighted cross-industry average sits near $4K per inspection, so this sector runs at or below the mean. Industries with higher average penalties typically see a greater share of serious, willful, or repeat violations, categories OSHA reserves for hazards likely to cause serious physical harm or where employers knowingly disregarded the law.
