The verdict

Combustioneer Corporation runs at 110% of its industry's injury rate - about level with the typical Plumbing,Heating and Air Conditioning Contractor workplace, earning a grade C.

Combustioneer Corporation: 3.1 TCR = 110% of Plumbing,Heating and Air Conditioning Contractor BLS 2.8 · 2y Form 300A (see methodology below)

Combustioneer Corporation safety composite

Combustioneer Corporation scores strongest on total case rate (tcr) (safer than 53% of same-industry peers) and weakest on dart rate (safer than 27%), 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).
