A large warehousing and distribution facility uses contractors for many of its maintenance activities. Contractors make up approximately 5% of the total workforce. However, an analysis of the accident statistics for the previous two years has shown that accidents involving contractor personnel, or arising from work undertaken by contractors, account for 20% of the lost-time accidents on site. (a)

(a)

Assuming that the accident statistics are correctly recorded, outline possible reasons for the disproportionate number of accidents involving contract work.

(10)

A manufacturing organisation with major on and off site hazards is analysing the risks and controls associated with a particular process and containment failure. Following process containment failure, a failure detection mechanism should detect the release. Once detected, an alarm should sound and a suppressant should be discharged. Additionally, in order to prevent an uncontrolled release, an operator is required to activate manual control measures following the discharge of the suppressant. The organisation has decided to analyse the risks associated with an uncontrolled release from the process using an event tree based on the table below: Activity Process containment failure and release Failure and release detection Alarm sounders Release suppression Manual control measures activated

(a)

From the information provided in the table, construct an event tree that shows the sequence of events following the process containment failure AND indicate where an uncontrolled release may occur.

(6)

(b)

Outline the benefits and limitations of event tree analysis.

(6)

(c)

Outline the methodology for a ‘cost benefit analysis’ for the process described.

(3)

Outline the factors that should be considered to determine whether the frequency of an uncontrolled release would be tolerable.
