Safety Insights for Charleston County
Charleston County operates an establishment with approximately 2,601 full-time equivalent workers in NORTH CHARLESTON, SC, classified under the Executive and legislative office combinations industry (NAICS 921140). Across 6 years of mandatory OSHA Injury Tracking Application (ITA) reporting, this employer has accumulated 706 recordable injuries, 46 occupational illnesses, and 1 workplace fatality. The average Total Case Rate (TCR) of 5.5 injuries per 100 full-time workers per year provides the anchor metric for the D letter grade (Poor Safety Record).
Benchmarked against the Bureau of Labor Statistics industry average of 3.2 for Executive and legislative office combinations, Charleston County's workforce experiences 173% 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 above the benchmark flags a higher-than-typical risk profile for jobseekers, insurers, and enforcement agencies to examine.
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 Charleston County as an employer, contractor, investment, or regulatory target should examine the yearly DART rate (days away, restricted, or transferred), the fatality count of 1, 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 (2023)
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.
55 DART incidents × 200,000 ÷ 4,245,493 hours worked = 2.59 DART
Methodology: 29 CFR 1904 — OSHA Form 300A recordkeeping
