MPH Occupational Health

This unit focuses on specific physical hazards found in the workplace and their effects on health, including noise, vibration, radiation, environmental temperatures (heat and cold), raised atmospheric pressures and lighting conditions.

The unit explores in depth the workplace exposure to physical agents, enabling the student to apply principles of risk management to a range of physical hazards that may be encountered in the workplace, and to demonstrate knowledge of how physical agents can be measured and controlled.

 The learning outcomes intend to:

• provide an understanding of the effects of noise on hearing and health, and the concept of hearing impairment and its assessment, prevention and control;
• enable students to investigate the factors causing vibration and its effects on health; including hand-arm and whole-body vibration, the recognition of and how to control symptoms and prevent ill health;
• provide an understanding of ionising and non-ionising radiations and their biological effects;
• provide an overview of the mechanisms and short/long term effects of working in environments where there is increased ambient pressure;
• enable students to assess the effects of heat and cold on occupational health and productivity; and
• assess how common causes of visual dysfunction may interfere with the ability to work, and the effects of the physical environment (lighting) on function at work.

• Noise
• Vibration
• Radiation
• Compressed Air Work and Commercial Diving
• Temperature and Work
• Light and Vision

Learning and teaching will take the form of online materials supported by online lectures, webinars, group discussion, tutorial, face-to-face workshops and practical experience days where relevant.

Blackboard and Zoom/Teams will be used for course materials including group discussions, announcements and updating of content, relevant lecture slides and additional reading, written example sheets and for online formative assessments

On completion, students should be able to:

• understand how to evaluate the likely effects of physical hazards on health, and advise on their prevention and management;
• know about the current legislation and guidance on the control of occupational exposure in relation to physical agents;
• be aware of measures that can be used to control exposure of workers to physical hazards and how to protect persons against the effects of these hazards; and
• understand the role of health surveillance for workers exposed to physical hazards.

On completion, students should be able to:

• understand the principles relating to the mechanisms and effects of physical agents on health and performance;
• be familiar with ways of measuring exposures to physical agents;
• understand the requirement for health surveillance for workers exposed to specific physical agents;
• appreciate the effects of co-morbidities on fitness for work in environments where there may be exposure to physical agents; and
• be familiar with short and long term effects of physical agents on workers and how these should be managed – including both clinical and workplace/environmental management.

On completion, students should be able to:

• understand how environmental/workplace noise is measured, the relevance of exposure(s) to noise for individuals, and how to test/interpret audiological function;
• understand how environmental/workplace vibration is measured, the relevance of exposure(s) to vibration for individuals, and how to perform/interpret health surveillance on workers exposed to vibration;
• understand the pathology, diagnostic features and treatment of decompression illness, and the effects of co-morbidities on workers’ fitness;
• be familiar with how the environmental/workplace thermal environment (temperature and humidity) is assessed, physiological responses to the thermal environment, and treatment for conditions caused by the thermal environment; and
• be familiar with how environmental/workplace lighting is assessed, how to perform/interpret health surveillance on workers’ visual function, and to advise on the effects of lighting and vision on performance.

On completion, students should be able to:

• understand the physical environment, in terms of measurement of physical exposures and effects on health; and
• know about health surveillance for workers exposed to physical agents and the effects of co-morbidities can be used in many fields of medicine (i.e. beyond the workplace environment).

Formative assessments with automatic feedback are available throughout the unit as an aid to understanding the course materials. Feedback for the summative assessments is provided by tutors via Blackboard. Students may also receive direct feedback from interaction with session leaders throughout the course of study.
