Grade compares Houston Arboretum's OSHA Total Case Rate to the BLS industry benchmark across 3 years of Form 300A filings (2016–2024). This reflects reported recordable injuries, not an independent safety inspection -- underreporting is a known limitation of employer self-recordkeeping.

Safety Insights for Houston Arboretum

Houston Arboretum operates an establishment with approximately 26 full-time equivalent workers in HOUSTON, AZ, classified under the Zoos and Botanical Gardens industry (NAICS 712130). Across 3 years of mandatory OSHA Injury Tracking Application (ITA) reporting, this employer has accumulated 2 recordable injuries, 0 occupational illnesses, and 0 workplace fatalities. The average Total Case Rate (TCR) of 2.5 injuries per 100 full-time workers per year provides the anchor metric for the C letter grade (Average Safety Record).

Benchmarked against the Bureau of Labor Statistics industry average of 3.1 for Zoos and Botanical Gardens, Houston Arboretum's workforce experiences 81% of the typical injury burden. This ratio matters because TCR already normalizes for hours worked, a 200,000-hour exposure base equals roughly 100 full-time workers, so establishments with very different headcounts can be compared directly. A TCR below the benchmark signals that controls, training, or automation may be outperforming peers.

Multi-year trend analysis is the single most reliable signal here: a one-year spike could reflect a single severe event, whereas sustained elevation across 3 reporting cycles points to systemic hazard exposure. Readers evaluating Houston Arboretum as an employer, contractor, investment, or regulatory target should examine the yearly DART rate (days away, restricted, or transferred), the fatality count of 0, and any year-over-year deterioration shown in the table below. All figures come directly from employer-submitted OSHA Form 300A summaries, there is no modeling, estimation, or third-party adjustment layered on top of the government data.

DART Rate, Transparent Calculation (2019)

DART (Days Away, Restricted, or Transferred) is computed by OSHA as incidents × 200,000 ÷ hours worked. The 200,000-hour denominator equals roughly 100 full-time workers, which lets establishments of very different sizes be compared directly.

1 DART incidents × 200,000 ÷ 56,168 hours worked = 3.56 DART

What this grade means for you

Use this grade as a relative read on Houston Arboretum's reported OSHA injury record, strong versus its Zoos and Botanical Gardens peers, but not a guarantee about any single site today.

  • At 81% of the Zoos and Botanical Gardens benchmark, Houston Arboretum reports fewer injuries than typical peers, still worth asking how safety is managed day to day. Know your rights
  • Judge this record against the wider Zoos and Botanical Gardens sector, where injury rates vary widely, before comparing it in isolation. See the industry
  • Grades reflect 2016–2024 filings; check the latest establishment record straight from OSHA, or look up a different employer. Look up another

Safety grades reflect employers' self-reported OSHA Form 300A filings from 2016 to 2024 and can lag current conditions. A grade is not a guarantee that any specific workplace is safe or unsafe today. See our methodology and disclaimer.
