Zero Zone, Inc. - Dyersville operates an establishment with approximately 31 full-time equivalent workers in DYERSVILLE, IA, classified under the Refrigeration equipment, industrial and commercial-type, manufacturing industry (NAICS 333415). Across 2 years of mandatory OSHA Injury Tracking Application (ITA) reporting, this employer has accumulated 3 recordable injuries, 0 occupational illnesses, and 0 workplace fatalities.

Benchmarked against the Bureau of Labor Statistics industry average of 3.3 for Refrigeration equipment, industrial and commercial-type, manufacturing, Zero Zone, Inc. - Dyersville's workforce experiences 170% 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 2 reporting cycles points to systemic hazard exposure. Readers evaluating Zero Zone, Inc. - Dyersville 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.

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.
1 DART incidents × 200,000 ÷ 67,398 hours worked = 2.97 DART
