Exposure to hazardous substances can lead to serious health risks in the workplace — understanding how to manage them is essential. The Diploma in COSHH (Control of Substances Hazardous to Health) Training Level 4 equips learners with the knowledge to identify, assess, and control workplace hazards effectively.
By completing this course, learners will understand UK COSHH regulations, risk assessments, and the correct implementation of control measures to create a safer work environment.
This course begins with Module 01: COSHH Explained, introducing the principles of hazardous substance control. Module 02: COSHH Regulations outlines the legal duties and employer responsibilities. In Module 03: Health Problems Related to Hazardous Substances, learners discover how different materials affect health. Module 04: Identifying Hazardous Substances focuses on recognising harmful agents in workplaces. Module 05: COSHH Risk Assessments teaches how to evaluate potential risks accurately. In Module 06: Control Measures and Monitoring, learners study preventive and monitoring strategies. Finally, Module 07: Implementing Control Measures explains how to apply and maintain safe practices to ensure compliance and protection.
This course starts off with a bang, by explaining what COSHH is, and what it does and does not cover. You’ll even discover what the COSHH symbols are and why they are important for identifying hazardous substances. This is the module which looks at the different categories of hazardous substances that can be found in the workplace. It also focuses on where these substances can be found and what effects they can cause on human health.
Module two begins to bring our awareness to the finer details of the COSHH legislation and also introduces the learner into other legislation which influences or supports COSHH. This information includes details of COSHH ‘guidance notes’ and ‘Approved Code of Practice,’ which is the basic outline describing what an employer needs to do to comply with COSHH.
This is where we take a closer look at the short term, midterm and long term implications of the effects of hazardous substances, and how exactly, they can cause harm. We also show the learner what implications acute and chronic exposure brings and who is at risk.
This module really helps the learner to understand what substances can cause asthma, fire, dangerous environments and more. It also brings more detail and information on warning labels and introduces the learner into chemical safety data sheets.
Module 5 is very focused on an important aspect of COSHH – the assessment processes. In this module, the learner will understand what COSHH assessments are and why they are necessary.
They’ll also learn step by step why each aspect of the assessment process is important and what considerations need to be made to complete the assessment adequately.
As you will discover in module 6, control measures are sophisticated and require a lot of thought and continual monitoring and management of them. If a control measure fails, then the health of the employees is at risk. It’s a big deal.
This is the last module in the COSHH training course, and it’s sort of like the icing on the top of the cake. It teaches the learner how to select, implement and maintain control measures. It also explains in more detail how to plan for emergencies and the reasons why health surveillance implementation might be something that employers may need to consider.
