Silas Bolef Company: 0.8 TCR = 30% of Electrical contractors BLS 2.8 · 2y Form 300A (see methodology below)

Silas Bolef Company safety composite

Silas Bolef Company scores strongest on total case rate (tcr) (safer than 85% of same-industry peers) and weakest on fatalities (safer than 51%), 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).
