Safety Insights for Milwaukee South Shore
Milwaukee South Shore operates an establishment with approximately 44 full-time equivalent workers in OAK CREEK, WI, classified under the Wastewater Treatment industry (NAICS 221320). Across 6 years of mandatory OSHA Injury Tracking Application (ITA) reporting, this employer has accumulated 6 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 D letter grade (Poor Safety Record).
Benchmarked against the Bureau of Labor Statistics industry average of 1.2 for Wastewater Treatment, Milwaukee South Shore's workforce experiences 187% 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 Milwaukee South Shore 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.
Verify This Employer with OSHA
All injury, illness, and fatality figures on this page are sourced from Milwaukee South Shore's own mandatory OSHA Form 300A summaries. Cross-check the underlying establishment record directly against the federal source — name, NAICS classification, recordable case totals, and inspection history are all searchable on OSHA's Establishment-Specific Injury and Illness Data system.

DART Rate — Transparent Calculation (2021)
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.
0 DART incidents × 200,000 ÷ 84,816 hours worked = 0.00 DART
