Explanation / Answer

a) The incident refers to "The Domino Theory".

According to this theory 88% of all accidents are caused by unsafe acts of people, 10% by unsafe actions, and 2% by act of God.

This theory was given by W. H. Heinrich in year 1931.

He also proposed 5 factor accident sequence as under-

1) ancestry and social environment

2) worker fault

3) unsafe act together with mechanical and physical hazards

4) accident

5) damage or injury

Heinrich proposed that to prevent the accident removal of one of the factor is required with 3rd being the key.

Thus in our caseprevention of accident can be done by removing and analysing theb 3rd factor ,i.e. unsafe act of workers.

b) Direct Cost is the cost which can be easily calculated for each activity.

Accident cost can be direct or indirect.

Direct cost includes compensation made to injured workers.

Here in our case there are no compensations made as no workers are injured.

Therefore there is no direct cost for this case.

c) Indirect cost included in this case-

1) Time away from job not covered by workers as 4 workers stopped working.

2) Cost of damage to material and equipment.

d) Cost of quality refers to the cost incurred for enhancing the quality of service or product.

thus 2 cost refers to cost of quality-

1) Preventive cost: It represents the cost incurred before the failure happened. It ensures that failure do not take place.

2) Appraisal cost: It represents the cost incurred for appraising the workers for enhancing the quality of service.
