Online COSHH Assessment Course for Workplace Safety

Module 1: Introduction to COSHH & Modern Developments

Begin with the purpose and practical scope of COSHH. You will examine why hazardous-substance management is a core part of workplace health protection and how COSHH sits within day-to-day risk management. The module introduces the types of substances and processes that can create health risks, while also making clear that not every harmful exposure comes from a product carrying a hazard label. You will consider the importance of current information, changing work practices and regular review. The module also establishes an important boundary: some hazards, including asbestos, lead and radioactive substances, are subject to their own specific regulatory regimes, so a sound COSHH approach starts by understanding what is and is not being assessed.

Module 2: Identifying Hazardous Substances & Smarter Data Use

Effective assessment depends on knowing what substances are present, how they are used and what information is available about them. This module develops a systematic approach to identifying hazardous products, process-generated dusts, fumes, vapours, mists, gases and biological agents. You will learn how product labels and Safety Data Sheets can support initial hazard identification and how digital inventories or structured records can make information easier to maintain and retrieve. The phrase hazardous materials classes is explored carefully: workplace COSHH decisions should be based on UK-relevant hazard information, exposure and task conditions rather than assuming that transport dangerous-goods classes are interchangeable with COSHH classifications. The aim is to build a reliable evidence base for the assessment that follows.

Module 3: Routes of Exposure & Predicting Health Impacts

A substance only creates a workplace health risk when there is a route and level of exposure capable of causing harm. This module examines the main exposure routes, including inhalation, skin contact and ingestion, together with task factors that can increase or reduce exposure. You will consider how the physical form of a substance, the way it is handled, frequency of use, duration of work and people involved can influence the assessment. The module also explores why health effects may be immediate or develop over time and why different people or tasks may require different controls. By linking hazard information to realistic exposure scenarios, you can move beyond generic statements and develop a more useful picture of who could be harmed and how.

Module 4: Conducting COSHH Risk Assessments

This module brings the earlier learning together into the central online COSHH assessment process. You will work through the logic of gathering information, identifying the hazardous substance or process, understanding the task, deciding who could be exposed, examining exposure routes and reviewing the controls already in place. From there, you will consider what further action is needed, who should take responsibility and when the assessment should be reviewed. Particular attention is given to recording significant findings and avoiding generic assessments that are not matched to the real workplace. The goal is to help you structure an assessment that supports practical decisions rather than treating the document itself as the end product.

Module 5: Control Measures & Safe Work Practices

Once risk has been assessed, the priority is to prevent exposure where reasonably practicable and control it adequately where prevention is not possible. This module explores the principles behind effective control, beginning with elimination or substitution and moving through process change, engineering controls, ventilation, safe systems of work and suitable protective equipment. You will consider why controls need to match the substance, task and exposure route, and why PPE should not automatically be treated as the first or only solution. The module also covers day-to-day practices that help controls remain effective, including maintenance, housekeeping, correct use, supervision and worker information. This creates a stronger link between the written assessment and what actually happens at work.

Module 6: Monitoring Exposure & Health Surveillance

Some work activities require more than an initial assessment. This module explains the role of exposure monitoring and health surveillance where the nature of the substance, work and potential health effects make them appropriate. You will explore the difference between monitoring the effectiveness of exposure controls and monitoring employees’ health for early signs of work-related harm. The module considers why surveillance should be linked to identifiable risks rather than used as a generic screening exercise, and why records must be handled appropriately. You will also review how monitoring results, worker feedback and changes in health can prompt a reassessment of controls. The emphasis is on using evidence to confirm whether arrangements remain effective over time.

Module 7: Incident Response & Emergency Preparedness

Even well-designed controls can fail, so COSHH management must include arrangements for foreseeable incidents, accidental exposure, leaks and spills. This module examines the planning needed before an emergency occurs: clear responsibilities, suitable first actions, communication routes, access to substance information and appropriate containment or evacuation arrangements. You will consider how incident information can reveal weaknesses in an assessment or control system and how follow-up action should feed into review and improvement. The module also distinguishes emergency preparedness from improvisation; the purpose is to ensure that people know what to do, what not to do and when specialist assistance is required. This supports a more resilient approach to hazardous-substance safety.

Module 8: Roles, Training & the Future of COSHH

The final module looks at how COSHH responsibilities are shared across an organisation. You will consider the importance of competent assessment, clear communication, worker instruction, supervision and training that matches the actual risks of the job. The module also explores how digital tools, better data management and emerging monitoring technologies may support future hazardous-substance management without replacing professional judgement or workplace-specific assessment. You will finish by considering review cycles, lessons from incidents, changes in substances or processes and the continuing-development needs of people with safety responsibilities. This helps position COSHH as an ongoing management process rather than a one-off paperwork exercise.

CPD Courses is listed by The CPD Standards Office as accredited provider number 60073. Provider accreditation and course-specific activity accreditation are not the same thing: the public CPD Standards Office directory currently names specific accredited activities rather than listing this Online COSHH Assessment course individually. For that reason, we do not present this course as a regulated qualification or guarantee that its hours will be accepted automatically by every employer, regulator or professional body.

If you need formal professional credit, check the requirements that apply to your role and keep appropriate evidence of your learning. Our guide to CPD accreditation explains the difference between accredited professional development, provider status and regulated qualifications.

We describe this programme as Level 3 COSHH CPD. This level description should not be interpreted as proof of an Ofqual-regulated Level 3 qualification unless a separate regulated-award specification is provided. Use the certificate as evidence of completed learning and continuing professional development, not as a professional licence or automatic proof of workplace competence.

What is an online COSHH assessment?

An online COSHH assessment is a structured way of recording how substances hazardous to health are used in a particular workplace, who may be exposed, how exposure could occur, what controls are already in place and what further action is needed. The assessment still needs to reflect the real task and workplace; an online form or template does not make a generic assessment suitable on its own.

Who should take this Online COSHH Assessment course?

The course is suitable for health and safety staff, supervisors, managers, facilities teams, laboratory and manufacturing staff, cleaning and maintenance personnel, and others who need a deeper understanding of hazardous-substance assessment and control. No formal entry requirements apply.

How long is the course?

This programme provides 80 hours of study. The online format allows you to work through the eight modules flexibly around other commitments.

What are hazardous materials classes in relation to COSHH?

The phrase hazardous materials classes can refer to different classification systems. In UK workplace COSHH, the key task is to identify substances hazardous to health using relevant product labels, Safety Data Sheets, process information and exposure conditions. Transport dangerous-goods classes serve a different purpose and should not be treated as a substitute for a COSHH assessment.

Does a Safety Data Sheet replace a COSHH assessment?

No. A Safety Data Sheet is an important source of information about a chemical product, including hazards, handling, storage and emergency measures, but it is not workplace-specific. A COSHH assessment must consider how the substance is actually used, who may be exposed and whether existing controls are adequate.

What exposure routes are considered in a COSHH assessment?

Assessment should consider relevant routes such as inhalation, skin contact and ingestion, together with how the substance is used and how often or how long people may be exposed. The importance of each route depends on the substance and task.

Does the course cover control measures?

Yes. The syllabus includes control measures and safe work practices, with emphasis on preventing exposure where possible and choosing proportionate controls such as substitution, process changes, engineering controls, ventilation, safe procedures and suitable PPE where appropriate.

Will I learn about exposure monitoring and health surveillance?

Yes. One module covers monitoring exposure and health surveillance. The course explains why these measures are relevant only in appropriate circumstances and how they can provide evidence about whether controls remain effective or whether early signs of work-related harm need attention.

Does the course cover chemical incidents and emergency response?

Yes. The syllabus includes incident response and emergency preparedness, including planning for accidental exposure, spills, control failures, communication and review after an incident.

How is this different from the 10-hour COSHH Awareness course?

This course is the deeper 80-hour assessment-focused route. The 10-hour COSHH Awareness course is better suited to learners who want a shorter foundation or refresher covering core COSHH principles.

Will I receive a certificate after completing the course?

A completion certificate is available after successful completion. CPD Courses is listed by The CPD Standards Office as accredited provider number 60073, but provider status is separate from individual activity accreditation. If you need formal CPD credit, confirm acceptance with the employer or professional body that will assess your learning.

Does completing this course make me legally competent to carry out every COSHH assessment?

No. The course can strengthen knowledge and provide structured professional development, but competence depends on the complexity of the task, relevant experience, workplace knowledge and any specialist training or advice required. Employers remain responsible for ensuring assessments are suitable and sufficient and that risks are properly controlled.
