D3 Materials Laboratory runs at 137% of its industry's injury rate - more dangerous than the typical Regulation and Administration of Transportation Programs workplace, earning a grade D.

D3 Materials Laboratory: 4.4 TCR = 137% of Regulation and Administration of Transportation Programs BLS 3.2 · 4y Form 300A (see methodology below)

D3 Materials Laboratory safety composite

D3 Materials Laboratory scores strongest on fatalities (safer than 53% of same-industry peers) and weakest on dart rate (safer than 10%), blended into one 0-100 breakdown against same-industry peers. A missing measure drops out and redistributes its weight rather than deflating the score. This is a per-dimension breakdown, distinct from the single letter grade above it (which weights TCR alone against the BLS industry benchmark).

D3 Materials Laboratory (20 employees, TCR 4.4) among 29 same-industry peers, split at the industry median of 172 employees and a TCR of 3.6

D3 Materials Laboratory has fewer employees than the Regulation and Administration of Transpo median and a higher injury rate than the industry's median TCR of 3.6. Workforce size and injury rate do not always move together within the same industry -- some of its smaller peers run higher rates than its larger ones, and vice versa.
