Safety Insights for Corona, CA- MFG
Corona, CA- MFG operates an establishment with approximately 52 full-time equivalent workers in CORONA, CA, classified under the Fabricated structural metal manufacturing industry (NAICS 332312). Across 3 years of mandatory OSHA Injury Tracking Application (ITA) reporting, this employer has accumulated 4 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 B letter grade (Good Safety Record).
Benchmarked against the Bureau of Labor Statistics industry average of 3.3 for Fabricated structural metal manufacturing, Corona, CA- MFG's workforce experiences 77% 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 Corona, CA- MFG 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 (2020)
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.
2 DART incidents × 200,000 ÷ 105,433 hours worked = 3.79 DART
Methodology: 29 CFR 1904 — OSHA Form 300A recordkeeping
