Safety Insights for MEPPI512-510
MEPPI512-510 operates an establishment with approximately 253 full-time equivalent workers in WARRENDALE, PA, classified under the Power circuit breakers manufacturing industry (NAICS 335313). Across 6 years of mandatory OSHA Injury Tracking Application (ITA) reporting, this employer has accumulated 33 recordable injuries, 0 occupational illnesses, and 0 workplace fatalities. The average Total Case Rate (TCR) of 2.2 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 Power circuit breakers manufacturing, MEPPI512-510's workforce experiences 68% 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 6 reporting cycles points to systemic hazard exposure. Readers evaluating MEPPI512-510 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 (2024)
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.
3 DART incidents × 200,000 ÷ 573,934 hours worked = 1.05 DART
Methodology: 29 CFR 1904 — OSHA Form 300A recordkeeping
