Section A: all questions compulsory 

Question 1

Safety Data Sheets (SDSs) provide important information to employers who are required to assess exposure to hazardous substances in their workplace. A typical SDS is divided into sections that contain different types of information.

Identify FIVE different types of information contained in a SDS, AND  for  EACH , outline  how the information could contribute to the assessment of risk or control of exposure. (10)

Question 2

(a) Identify  the possible health effects from working in a cold store at sub-zero temperatures. (4)

(b) Outline control measures to minimize the risks to persons who work in a cold store at sub-zero temperatures. (6)

Question 3

Operators use a range of solvents in a manufacturing process.

Describe a monitoring strategy that could be used to measure the exposure of the operators to solvent vapors. (10)

Question 4

A research laboratory undertakes necessary work with biological agents. These biological agents are categorized as extremely hazardous, being placed in the highest hazard group.

Outline a range of technical controls that should be used to minimize the risks to those working in the laboratory, where elimination or substitution of the hazard is not possible. (10)

Question 5

A worker on a production line is required to stand in front of hisworkbench, which is 750mm deep and set at waist height. The worker must frequently lift a 20kg item of equipment from his workbench onto an unpowered roller conveyor which is behind it. The conveyor is set slightly higher than the workbench.

(a) Explain why the current method of working is not acceptable. (4) 

(b) Outline practical measures that might be considered to reduce the ergonomic related risk to the worker. (6)

Question 6

Construction workers regularly use cement. Several of the long-termworkers and one of the new recruits have complained about red and sore skin on their hands.

(a) Explain the possible reasons for the symptoms they are experiencing. (6)

(b) Outline control measures that could be used to minimize these symptoms in this situation. (4)

Section B: three from five questions to be attempted

Question 7

A slightly corrosive solution is used as a treatment in part of amanufacturing process. The solution is applied by hand brushing. Forthis process, other methods of application are not practicable.

(a) Outline the factors that should be considered in the selection of personal protective equipment to adequately protect the skin and the eyes of those involved in the process. (10)

(b) Outline the content of a training program that will assist workers to use the personal protective equipment correctly. (5)

(c) Identify a range of practical measures (other than training) that can be taken to encourage the use of the personal protective equipment and maintain its effectiveness. (5)

Question 8

Managers are concerned at the increase in stress-related absence.

(a) Identify a range of information sources that can be used to assess the levels of stress experienced by their workers. (6)

(b) Outline organizational and personal factors that can contribute to the incidence of work-related stress. (14)

Question 9

A small printing company operates a number of printing machines whichare located in an open-plan workshop. Following a noise survey, the company discovers that their workers are being exposed to high average daily noise levels. The noise levels exceed regulatory exposure limits.

(a) Describe the acute and chronic physiological effects of exposure to high noise levels on the individual. (4)

(b) Explain what steps the company should take to protect workers. (16)

In your answer clearly explain the range of technical and organizational control measures that could be introduced.

Question 10

 A large manufacturing company is to introduce a health promotion program.

(a) Outline the purpose of a health promotion program. (2)

(b) Identify issues the health promotion program should address AND outline the way in which EACH  issue could be promoted. (10)

(c) Identify FOUR occupational health specialists who may be involved in the health promotion program, AND  outline how EACH  specialist could contribute to the program. (8)

Question 11

(a) Identify FIVE workplace sources of ionizing radiation. (5)

(b) Outline control measures that should be in place when persons may be exposed to ionizing radiation at work. (15)
