The verdict

DDL-CA runs at 1488% of its industry's injury rate - far more dangerous than the typical Testing Laboratories workplace, earning a grade F.

DDL-CA: 7.4 TCR = 1488% of Testing Laboratories BLS 0.5 · 4y Form 300A (see methodology below)

DDL-CA safety composite

DDL-CA scores strongest on fatalities (safer than 50% of same-industry peers) and weakest on total case rate (tcr) (safer than 4%), 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).

DDL-CA (35 employees, TCR 7.4) among 29 same-industry peers, split at the industry median of 81 employees and a TCR of 1.0

DDL-CA has fewer employees than the Testing Laboratories median and a higher injury rate than the industry's median TCR of 1.0. 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.
