Safety Insights for H Nu Solar LLC
H Nu Solar LLC operates an establishment with approximately 21 full-time equivalent workers in KAHULUI, HI, classified under the Alternative energy (e.g., geothermal, ocean wave, solar, wind) structure construction industry (NAICS 237130). Across 4 years of mandatory OSHA Injury Tracking Application (ITA) reporting, this employer has accumulated 5 recordable injuries, 0 occupational illnesses, and 0 workplace fatalities. The average Total Case Rate (TCR) of 5.8 injuries per 100 full-time workers per year provides the anchor metric for the F letter grade (Failing Safety Record).
Benchmarked against the Bureau of Labor Statistics industry average of 2.8 for Alternative energy (e.g., geothermal, ocean wave, solar, wind) structure construction, H Nu Solar LLC's workforce experiences 208% 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 4 reporting cycles points to systemic hazard exposure. Readers evaluating H Nu Solar LLC 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.
1 DART incidents × 200,000 ÷ 300,388 hours worked = 0.67 DART
Methodology: 29 CFR 1904 — OSHA Form 300A recordkeeping
