To control accident first unsafe condition has to be controlled.
Then unsafe acts has to be attacked. This is harder to control and less immediate in effect.

Technique of accident prevention contd.
Hazard assessment and evaluationHazard rating = Frequency x (severity + MPL + Probability )
= 1 X (3+45+15) = 63
Frequency of occurrence 1,2,3 or 10 times a year
Severity rating of accident 1, 2, 3 etc
MPL Maxm possible loss fatal 50, loss of two limbs 45, .. scratch 1
Probability Imminent 50, hourly 35, daily 25, once in a year - 5
If hazard rating is >100 action immediate
50 to 100 - today

Accident investigation
The purpose is to discover hazardous conditions and practices, so that accident from similar causes may be prevented. Idea to fix the blame should be definitely avoided because this may lead to covering up amongst the employees. It should be a fact finding method not fault finding.
