The verdict

Twitter runs at 50% of its industry's injury rate - far safer than the typical industry workplace, earning a grade A.

Twitter: 1.5 TCR = 50% of industry BLS 3.0 · 5y Form 300A (see methodology below)

Twitter safety composite

Twitter scores strongest on total case rate (tcr) (safer than 84% of same-industry peers) and weakest on fatalities (safer than 50%), 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).

Twitter (34 employees, TCR 1.5) among 29 same-industry peers, split at the industry median of 43 employees and a TCR of 3.5

Twitter has fewer employees than the industry median and a lower injury rate than the industry's median TCR of 3.5. 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.
