This COSHH Awareness training course is beneficial for all employees working where hazardous substances are present.  It will be particularly beneficial for those managing and refining safe ways of working with hazardous substances.

Hazardous substances are more common than you might imagine.  For example, bleach used for cleaning is a hazardous substance.

COSHH refers to the Control of Substances Hazardous to Health Regulations 2002.  This regulation is designed to protect employees from hazardous substances.

Every workplace where ‘hazardous substances’ are present have duties under COSHH regulations.

Our online COSHH course provides the knowledge needed to comply with COSHH regulations and help keep colleagues safe.

Anyone managing or supervising staff in a workplace where hazardous substances are present should have an understanding of their duties under the COSHH regulation.

Some sectors where COSHH applies;

  • Cleaning – cleaning materials can cause localised burns and skin complaints
  • Construction – we have a dedicated COSHH for Construction course.  Working where Asbestos could be present requires specific awareness training.
  • Bakeries  – flour and bakery dust can cause irritation of eyes and nose, skin problems and asthma
  • Garages – paints, solvents, oils and grease, and exposure to exhaust fumes can all damage their health
  • Healthcare – exposure to biological agents can cause infection.
  • Laboratories – exposed to chemicals, biological agents and flammable substances.
  • Warehouses – Many handle a range of hazardous substances.

In this first unit we explain what hazardous substances are, and the applicable legislation.


In this second unit, we explore the health risks when working with and near hazardous substances, typical safe systems of work and practical action that can protect you and others.


In this final unit, we look at employer and employee responsibilities when working with hazardous substances, including how to store and dispose of them safely.  We also look at how to respond to an accidental spill.

What is a hazardous substance?

In COSHH regulations a hazardous substance is ‘any substance that may cause harm to your health’.  This is a broad definition, however, common examples include;

  • chemicals
  • products containing chemicals
  • fumes
  • dusts
  • vapours
  • mists
  • nanotechnology
  • gases and asphyxiating gases and
  • biological agents (germs). If the packaging has any of the hazard symbols then it is classed as a hazardous substance.
  • Germs
  • Any substance with a WEL or Workplace Exposure Limit

Asbestos, lead and radioactive substances are all hazardous substances under COSHH.  Because the hazards are so high they have their own specific regulations outlining what employers must do.

What are the 9 hazard symbols used to identify hazardous substances?

The 9 hazards warning symbols below are used on packaging across Europe to identify the hazard of a particular substance.  Multiple hazard warning symbols are used when a substance has multiple hazardous properties.

What do COSHH regulations require?

In short, COSHH regulations require that employers reduce the risk to staff from hazardous substances to as low as reasonably practicable.

In practice this means first undertaking a COSHH assessment.  Walking round your business and noting which harmful substances are or could at time be present.  Then consider what activities expose your staff to these substances and finally then what can be done to reduce the risk that someone might be harmed.  All the steps you take should be documented.

One helpful step when substances cannot be eliminated from the workplace is to provide Hazardous Substances training to staff so they are aware of the risks and can therefore better avoid them.

Why take this online COSHH training?

Every year, thousands of workers are made ill by hazardous substances, contracting lung disease such as asthma, cancer and skin disease such as dermatitis.  You are probably aware of hazardous substances that are used in your workplace.   Or are created as a consequence of work activities for example welding fumes or quarry dust.

Although the hazard from a substance is constant, the risk from that substance varies.  For example, moving a flammable substances further away from an ignition source reduces the risk of explosion.

COSHH Regulations simply require employers to periodically assess the risks, and then adequately control them.

This online COSHH course helps to control risks by providing the knowledge needed to recognise hazards and respond appropriately.

Should I take this COSHH course or Hazardous Substances course?

This COSHH course covers similar content but emphasises more about the regulations and how to implement safe systems of work.  This is more applicable to supervisors and managers.  The Hazardous Substances course focuses more the behaviours that staff should adopt like safe storage and always wearing appropriate PPE.
