Hazardous Substances


Using chemicals or other hazardous substances at work can put people’s health at risk, causing diseases including asthma, dermatitis or cancer. In addition there are also biological hazards that can cause harm to workers. Every year, thousands of workers are made ill by hazardous substances, contracting a range of diseases or conditions that costs organisations many millions of pounds each year and affects the quality of life of individuals. Employers are responsible for taking effective measures to control exposures to biological hazards, chemicals and hazardous substances and to protect workers health. The primary piece of legislation relating to chemicals and hazardous substances is the Control of Substances Hazardous to Health Regulations (COSHH).
The Regulations and guidance requires that employees are trained, instructed and informed about their involvement in the assessment process, responsibilities and the use of control measures.

Aims of the Course

Hazardous Substances aims to raise the awareness of employers and employees to the hazards associated with the presence and use of chemicals and hazardous substances and the actions that are necessary to control the risks. At the end of the training trainees will be able to:

  • Appreciate by use of examples the main groups of substances and agents that are hazardous to health including chemicals, substances, biological and physical agents
  • Recognise the main routes of entry of chemicals and biological hazards into the body or areas most at risk from physical agents
  • Recognise common labelling and signs
  • Recognise the various forms that chemicals, substances and biological agents can be presented in
  • Appreciate how the quantity and duration of exposure affects risk
  • Appreciate the issue of sensitisation
  • Appreciate the significance of skin contact as the major cause of occupational disease making reference to allergens in particular latex and exposures to sunlight
  • Appreciate how simple self examination can form part of a health surveillance programme
  • Recognise a hierarchy of controls and reference to the limitations of personal protective equipment (PPE)
  • Appreciate the need to store and take care of issued PPE and report any defects
  • Appreciate the requirements for the safe

Who is it for?

The course has been developed for managers and employees at all levels in the organisation to ensure they have the necessary awareness of hazardous substances, chemicals and biological hazards and the measures that are typically used to control the risks.

How is it Delivered?

Hazardous Substances can be delivered online or through a computer network to each trainee at their desktop or laptop. We can also provide the course to be integrated into a SCORM compliant LMS. The training can be completed at the employees own pace by ‘book marking’ and recording progress and returning to the training at a later stage. In delivering the training in this way the normal costs of training are reduced whilst still achieving the desired awareness and compliance with the organisation’s legal responsibilities. At the end of the training the trainee will complete an assessment.

Compliance Record Keeping Easily Solved

An invaluable feature of Praxis42 eLearning modules is our learning management system called the eSP, our eSolutions Platform. This solves the problem of compliance record keeping by recording all training and completion of courses and making these records available for you to view and manage electronically. No more struggling to find training records should you have a visit from the enforcing agency or an audit. Training certificates can be printed by the trainee once the course is completed and the end assessment successfully passed.

Course Summary

Hazardous Substances training from Praxis42 helps managers and employees recognise the hazards associated with working with chemicals, substances, biological hazards and exposures to physical agents. The course uses all the latest HSE guidance including ‘Working with substances hazardous to health’ INDG136, covers typical control measures and the globally harmonised international pictograms.
