• Strike another worker• Run into equipment causing
property damage• Damage Car• Roll and crush worker
• Crush• Pinch Points• Tool hit worker in head• Car fall off - damage
• Repetitive Strain• Back strain from body position• Eye Injury• Crush toes• Cut to hands• Crush toes• Back Strain/Sprain• Shoulder Strain/Sprain• Abrasion• Damage clothes
Step 5 – Rank the Hazard and Risk Three (3) steps of a ranking Hazard & Risk.
• How bad? (consequences)• How often? (exposure)• How likely? (probability)

Severity of Consequences
25
Level RatingNumerous fatalities; extensive damage, major disruption 100Several fatalities; damage $500,000 to $999,999 75Fatality; damage $100,000 to $499,999 50Extremely serious injury/disease
(permanent disability); damage $1,000 to $99,999 30Disabling injuries, reversible tissue damage;
damage up to $999 10Minor cuts, bruises, irritations; minor damage 2
Worker Exposure
26
Level RatingContinuously (or many times daily) 10Frequently (approximately once daily) 6Usually (from once per week to once per month) 3Occasionally (from once per month to once per year) 2Rarely (it has been known to occur) 1Very rarely (not known to have occurred,
but considered remotely possible) 0.5
Probability
27
Level Rating Are the most likely & expected result. 10Are quite possible, would not be unusual, having a
50/50 chance. 6Would be an unusual sequence or coincidence. 3Would be remotely possible coincidence. It has been known,
however, to have happened. 1Would be extremely remote but conceivable possible.
Has never happened after many years of exposure. 0.5Would be practically impossible: a “one in a million” possibility. Has never happened despite exposure over many years. 0.1
