Unit IA: International management of health and safety TUESDAY 3 JULY 2012 3 hours, 0930 to 1230 10 minutes reading time is allowed before the start of this examination. You may not write anything during this period.

Answer both Section A and Section B

SECTION A This section contains six questions. Answer ALL SIX questions. All questions carry equal marks. The maximum marks for each question, or part of a question, are shown in brackets. You are advised to spend about 15 minutes on each question. Start each answer on a new page.

1

Outline issues that should be considered when planning a health and safety inspection programme.

(10)

Information on the specific workplace conditions or behaviours that might be covered in an inspection is not required.

2

(a)

An extract from a company annual report is given below. Comment critically on the suitability of the content in providing information to the stakeholders.

(5)

‘The company has done much better at health and safety in the last year compared to previous years. In 2008 there were 170 accidents that required first-aid treatment compared to 180 in 2007, 185 in 2006 and 240 in 2005. This significant reduction is due to our new health and safety manager and a reduction in staff numbers from 1500 in 2005 to 1400 in 2006 and 1300 in 2007 to 900 in 2008, which also helps reduce business costs. Fatalities were also reduced from 11 in 2007 to 4 in 2008, a significant decrease.’ The management team is confident of further reductions in 2009. (b)

Calculate the non-fatal accident incidence rates AND comment on the findings.

3

An organisation is proposing to move from a health and safety management system based on the International Labour Organisation ILO OSH 2001 model to one that aligns itself with BS OHSAS 18001. Outline the possible advantages AND disadvantages of such a change.

(a)

(b)

(a)

Outline the use and limitations of fault tree analysis.

Under fault conditions, the operator is at risk from a crushing injury due to either (a) the press tool falling by gravity or (b) an unplanned (powered) stroke of the press. The expected frequencies of the failures that would lead to either of these effects are given in the table below: Failure type Flexible hose failure Detachment of press tool Hydraulic valve failure Activation button failure Electrical fault

(10)

Outline, with reasons, whether or not the level of risk calculated should be tolerated.

(4)

Assuming that the nature of the task cannot be changed, explain how the fault tree might be used to prioritise remedial actions.
