Overview

This unit evaluates exposure control strategies, including equipment and techniques used in controlling exposure to hazards. The unit examines various practice-based topics including the role of ventilation, containment, behavioural factors and PPE in the workplace. A range of work settings are evaluated with analysis of key issues in exposure control for example, control of dermal exposures and implementation of effective dermal risk assessment, communicable disease and infection control in workplaces..

Aims

This unit will introduce students to the principles and concepts of good control practice and enable them to develop strategies and reasonably practicable controls as part of integrated occupational health and hygiene programmes to minimise the risks from exposure to hazardous substances in the workplace. The unit builds on the stages of anticipation, recognition and evaluation of exposures, examining the ways in which the exposures can be controlled. Evaluation of control strategies for various hazards and the techniques available to develop health surveillance system in a variety of different workplaces are covered extensively.

Learning outcomes

The learning outcomes intend to allow students to:

  • Develop critical understanding of process control and the need for judgement in setting priorities.
  • Use evidence-based practice to examine the technical and legal factors involved in process control.
  • Critically analyse risks to health from hazardous substances in the workplace and apply the principles of good control practice and hierarchy of controls to identify, develop and implement reasonably practicable control strategies and integrated control regimes.
  • Identify and specify reasonably practicable engineering measures to control exposure to hazardous substances.
  • Identify and specify organisational and management measures as part of a control regime.
  • Select appropriate personal protective equipment to minimise exposure to hazardous substances.
  • Evaluate the effectiveness of control measures, programmes and strategies.
  • Make independent decisions that are based on evidence and research in relation to behavioural factors, ergonomics and cost benefit analyses.
Category of OutcomeOn completion, students should be able to:
Knowledge and understanding 
  • Apply and synthesis knowledge of the concepts and principles of managing ventilation systems used to control hazardous substances in the workplace.
  • Demonstrate critical thought and application in relation to the types of PPE available when working with hazardous chemicals and other forms of PPE available for use with some physical and mechanical risks.
  • Demonstrate critical understanding of the range of strategies that can be used to control dermal exposure and how these fit into the hierarchy of controls.
  • Demonstrate understanding of factors that influence human behaviour and the significance of behavioural change in reducing exposure risk in the workplace
  • Apply the principles of the hierarchy of control and the management of health risks to develop control strategies for workplace health hazards. 
Intellectual skills 
  • Critically evaluate the key aspects of a well-developed control strategy and health protection programme.
  • Critically evaluate existing measures used to control exposure, including ventilation and PPE.
  • Critically assess the range of strategies that can be used to motivate and perpetuate behaviour change.
  • Interpret outcomes of peer reviewed research in the context of exposure control practice and propose solutions as a result of the research findings. 
Practical skills 
  • Critically evaluate strategies used for the control of occupational exposures in a range of workplace settings.
  • Communicate developments in practice to a wide audience.
  • Use principles of evidence-based practice to review and improve practice.
  • Identify areas of uncertainty to formulate focused, answerable questions.
Transferable skills and personal qualities 
  • Independently gather, organise, and evaluate information from a variety of sources and develop an evidence-based approach to occupational hygiene practice.  
  • Understand the influence of a wide range of factors when negotiating with others within the field of occupational hygiene.
  • Communicate complex ideas in concise written formats appropriate for a range of stakeholders
  • Apply and synthesise knowledge of health, legislation, and business in the management of work-related issues affecting both individuals and groups.
