Hazard Identification and Risk Rating

For each hazard: assess Likelihood (L) and Consequence (C) before controls. Calculate Risk (R = L x C). Then specify controls and re-rate residual risk.

L: 1 = Rare, 2 = Unlikely, 3 = Possible, 4 = Likely, 5 = Almost certain
C: 1 = Insignificant, 2 = Minor, 3 = Moderate, 4 = Major, 5 = Catastrophic
# Hazard L C R Control Measures L C R
