Trend analysis for MasTec MNS Wireline
Between 2021 and 2024, MasTec MNS Wireline's Total Case Rate improved from 3.5 to 1.8 recordable injuries per 100 full-time workers, a 48% decrease across 3 years of OSHA reporting.
The safest year on record was 2024, at a TCR of 1.8, while 2022 saw the highest rate, at 3.5, a spread of 1.7 points between the best and worst reporting years. That's a comparatively narrow spread, suggesting a fairly consistent safety record across the 4 years with a usable rate on file, rather than one outlier year skewing the multi-year average.
Summed across those 4 reporting years, MasTec MNS Wireline recorded 245 total injuries and illnesses, with no fatalities reported in any of those years. Readers comparing establishments should weigh the 4-year trend above alongside establishment size, since a larger workforce naturally accumulates more raw incidents even at a lower per-100-worker rate.

DART Rate, Transparent Calculation (2024)
What is the DART rate formula?
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.
57 DART incidents × 200,000 ÷ 8,835,582 hours worked = 1.29 DART
Methodology: 29 CFR 1904, OSHA Form 300A recordkeeping
