Industry-average TCR has held steady across this span (4.3 → 4.3) · NAICS 423720
According to OSHA's Injury Tracking Application (2016–2024), Plumbing supplies merchant wholesalers ranks #319 of 540 industries with at least 100 rated establishments by rated-subset average Total Case Rate (same basis as the most-dangerous-industries ranking; higher TCR means more injuries). The Plumbing supplies merchant wholesalers sector (NAICS 423720) encompasses 983 distinct employer establishments currently reporting to OSHA's Injury Tracking Application. Across this cohort, workers have logged 6,929 recordable injuries during the 2016–2024 reporting window. The industry-weighted average Total Case Rate (TCR) of 4.1 injuries per 100 full-time workers per year is computed on the 853 establishments with a credible rate (see methodology). Because OSHA's ITA mandates submission from establishments with 250+ employees plus all high-hazard industries at 20+ employees, this dataset represents a structural slice of U.S. workplace risk rather than a voluntary sample.
The Bureau of Labor Statistics publishes a separate national benchmark TCR of 2.2 for this NAICS code, derived from the BLS Survey of Occupational Injuries and Illnesses. Comparing the two, the ITA-reported rate of 4.1 is higher than the BLS benchmark, a gap that typically widens when the industry contains many large, high-exposure establishments required to file ITA reports. Employers in the table below are sorted so you can see how far individual establishments deviate from both the industry average and the national benchmark.
The practical value of industry-level safety data is threefold. First, jobseekers can gauge whether a prospective employer is better or worse than its industry peers, not just absolute injury counts, which tilt toward larger payrolls. Second, insurers and workers' compensation carriers use sector TCR as a baseline for experience-modification adjustments. Third, safety professionals benchmark their own programs against the cohort median. Use the grade-sorted employer list below to identify specific establishments within Plumbing supplies merchant wholesalers that outperform or underperform the sector average, and click through to each record for year-by-year injury, illness, and fatality breakdowns.
