What is the difference between COSHH and infection control?

COSHH is a legal framework that covers all hazardous substances, including biological agents like bacteria and viruses. Infection control is a broader set of practices aimed at preventing the spread of infections, which includes COSHH principles but also covers hand hygiene, isolation, and vaccination. In health and social care, COSHH helps manage the risks from substances used in infection control, such as disinfectants.

Do I need a COSHH risk assessment for every substance in a care home?

Yes, but you can group similar substances (e.g., all cleaning products) if they have the same hazards and controls. The key is to identify substances that are hazardous and assess the risks they pose. For example, bleach and disinfectant wipes may be assessed together if used similarly. Always refer to safety data sheets for guidance.

What should I do if I spill a hazardous substance?

Follow your workplace's emergency procedures. Generally, you should alert others, evacuate the area if necessary, and use a spill kit if available. Wear appropriate PPE (e.g., gloves, apron) and contain the spill using absorbent materials. Dispose of waste according to COSHH guidelines. Report the incident to your supervisor and document it.

How often should COSHH training be updated?

COSHH training should be provided when a person starts a role and then updated regularly, typically annually, or whenever there is a change in procedures, substances, or legislation. Refresher training ensures staff remain aware of risks and control measures. Employers must also provide information and instruction as needed.

Can I use a substance without a safety data sheet?

No, you should never use a substance without a safety data sheet (SDS). The SDS provides essential information about hazards, safe handling, and emergency measures. If an SDS is missing, contact the supplier or manufacturer. Using an unknown substance could put you and others at risk and may breach COSHH regulations.

What is the hierarchy of control in COSHH?

The hierarchy of control is a step-by-step approach to managing risks: 1) Elimination – remove the hazard entirely (e.g., use a non-hazardous cleaner). 2) Substitution – replace with a safer alternative. 3) Engineering controls – isolate people from the hazard (e.g., local exhaust ventilation). 4) Administrative controls – change how people work (e.g., training, safe systems of work). 5) Personal protective equipment (PPE) – as a last resort (e.g., gloves, masks).

This subtopic introduces learners to the core principles of the Control of Substances Hazardous to Health (COSHH) regulations, focusing on the legal framework for managing hazardous substances in the workplace. It covers the systematic approach to identifying hazards, assessing risks, and implementing control measures to protect health. Practical application includes understanding employer and employee duties to prevent exposure to hazardous substances.

Transcend Level 2 Award in the Control of Substances Hazardous to Health

Topic Overview

The Control of Substances Hazardous to Health (COSHH) is a key piece of UK legislation that requires employers to protect workers and others from the risks of hazardous substances. In Health & Social Care settings, COSHH covers a wide range of substances, including cleaning chemicals, disinfectants, medications, bodily fluids, and waste. Understanding COSHH is essential for maintaining a safe environment for both staff and service users, and it forms a core part of health and safety training in care roles.

This topic explores the legal duties under COSHH, the types of hazardous substances encountered in health and social care, and the practical steps needed to manage risks. Students will learn about risk assessment, control measures, personal protective equipment (PPE), and emergency procedures. Mastering COSHH not only helps prevent accidents and ill health but also ensures compliance with regulatory standards, which is vital for any care setting.

As part of the Transcend Level 2 Award, this unit builds foundational knowledge for safe practice. It connects to broader themes such as infection control, manual handling, and safeguarding. By the end of this topic, students should be able to identify hazards, implement controls, and respond appropriately to incidents involving hazardous substances.

Key Concepts

Core ideas you must understand for this topic

→Hazard vs. Risk: A hazard is something with the potential to cause harm (e.g., bleach), while risk is the likelihood that harm will occur. COSHH focuses on controlling risks.
→Routes of Entry: Hazardous substances can enter the body via inhalation (breathing in), ingestion (swallowing), absorption (through skin or eyes), or injection (e.g., needlestick injury).
→Risk Assessment: A systematic process to identify hazards, evaluate risks, and implement control measures. Must be recorded and reviewed regularly.
→Hierarchy of Control: A step-by-step approach to reducing risk: elimination, substitution, engineering controls (e.g., ventilation), administrative controls (e.g., training), and PPE (as a last resort).
→Safety Data Sheets (SDS): Documents provided by manufacturers that detail the properties, hazards, handling, and emergency measures for a substance. Essential for risk assessment.

Learning Objectives

What you need to know and understand

Outline the key requirements of the COSHH regulations.
Identify common hazardous substances in health and social care settings.
Describe the steps involved in a COSHH risk assessment.
Explain the hierarchy of control measures for hazardous substances.
Recognise the importance of health surveillance for workers exposed to hazardous substances.
State the responsibilities of employers and employees under COSHH.

Assessment Criteria

Key criteria assessors look for in your portfolio

Award credit for correctly identifying the main hazardous substances relevant to the care environment, such as cleaning chemicals, bodily fluids, and medications.
Credit for demonstrating understanding of the hierarchy of control, emphasising elimination or substitution as the most effective measures.
Credit for explaining the need for safety data sheets and COSHH assessments in managing risks.
Credit for outlining the role of personal protective equipment (PPE) as a last resort after other controls.

Assessment Guidance

Guidance for achieving higher grades

💡Always relate answers to the specific context of health and social care, using examples like handling soiled linen or cleaning products.
💡For questions on control measures, structure your response using the hierarchy of control, starting from elimination down to PPE.
💡Ensure you can explain the difference between a hazard and a risk, as this is a common assessment topic.
💡When answering questions about risk assessment, always mention the five steps: identify hazards, decide who might be harmed and how, evaluate risks and decide on precautions, record findings, and review/update. This structure gains marks.
💡Use specific examples from health and social care, such as handling clinical waste or using disinfectants in a care home. Generic answers lose marks; context shows understanding.
💡Remember that COSHH requires employers to provide information, instruction, and training. Mentioning this demonstrates knowledge of legal duties beyond just risk assessment.

Common Mistakes

Common errors to avoid in your coursework

Confusing COSHH with general health and safety duties or infection control procedures.
Believing that wearing PPE alone is sufficient to control exposure without considering other control measures.
Assuming that only chemicals labelled as 'dangerous' are covered by COSHH, ignoring biological agents and naturally occurring substances.
Failing to recognise the importance of recording risk assessments and reviewing them regularly.
Misconception: 'COSHH only applies to chemicals like cleaning products.' Correction: COSHH covers all hazardous substances, including biological agents (e.g., blood, viruses), dusts (e.g., flour), and fumes (e.g., from sterilising equipment).
Misconception: 'If I wear gloves, I don't need to follow other control measures.' Correction: PPE is the last line of defence. It should only be used when other controls (e.g., substitution, ventilation) are not enough, and it must be used correctly.
Misconception: 'Risk assessments are just paperwork and don't need updating.' Correction: Risk assessments must be reviewed regularly, especially after an incident or change in procedures, to remain effective.
