COSHH Assessments

These are complex times, and while we are all learning to operate differently, RPS are working to make it easy for our clients and their teams to connect with us. 


We've designed a new way to deliver COSHH assessments remotely - where RPS qualified occupational hygienists are, in many cases, able to undertake the compilation or review process as a desktop exercise.

A COSHH assessment focuses on the hazards and risks presented by substances in the workplace. Not always labelled as ‘hazardous’, sometimes these substances, such as paint, bleach or dust, can occur from natural materials but still be harmful. Substances can take many forms including:

  • Chemicals
  • Products containing chemicals
  • Fumes
  • Dusts
  • Vapours
  • Mists
  • Nanotechnology
  • Gases and asphyxiating gases
  • Biological agents

COSHH regulations

COSHH regulations require employers to manage substances which can be harmful to human health. An assessment is carried out for the purpose of identifying hazardous substances present, whether the precautions you have taken are acceptable, and what control measures are in place. The assessment will contain relevant information on the process, substances, risks and control measures.

At RPS, this is carried out by a 3-step process:

  • Gathering information about the substances, associated work and practices
  • Evaluating the risks to health
  • Deciding on the necessary measures (controls) to comply with regulations 7-13 of the COSHH regulations

A completed assessment may conclude that the current controls are adequate, or that further controls are necessary to protect workers. 

A completed assessment will help to reduce operator exposure to low level risks.

The regulations stipulate that assessments should be reviewed every 2 years from completion. If any of the following are applicable, then they must be reviewed sooner:

  • Modification of existing, or installation of new, process plant or equipment
  • A change of process
  • Change in volume of production
  • New substances or new evidence on hazards of existing substances
  • Alteration of control techniques/equipment
  • Ill health related to work is reported
  • Monitoring or health surveillance indicates loss of control
  • New or improved techniques become reasonably practicable
