The principles of Infection Prevention and Control
This subtopic equips learners with foundational knowledge to prevent and control infections in social care settings, focusing on legislative compliance, risk assessment, and proper use of personal protective equipment and hygiene. It emphasizes the shared responsibility of care staff to safeguard vulnerable individuals from healthcare-associated infections through systematic procedures and individual accountability. Mastery of these principles is essential for safe practice and meeting regulatory standards, directly impacting the quality of care and patient wellbeing.
Assessment criteria
Topic Overview
The TQUK Level 2 Award in Prevention and Control of Infection (RQF) equips learners with essential knowledge to minimise the spread of infections in health and social care settings. This qualification covers the causes of infections, the chain of infection, standard precautions, and the importance of hand hygiene and personal protective equipment (PPE). It is crucial for anyone working in care environments, as effective infection control protects both service users and staff from healthcare-associated infections (HCAIs).
Understanding infection prevention is a fundamental aspect of safe practice in health and social care. The course emphasises the legal and regulatory framework, including the Health and Safety at Work Act 1974 and the Control of Substances Hazardous to Health (COSHH) Regulations. Learners explore how microorganisms such as bacteria, viruses, and fungi cause disease, and how breaking the chain of infection at any point can prevent transmission. This knowledge is directly applicable to daily tasks like cleaning, waste disposal, and managing spills.
Mastering infection control not only ensures compliance with national standards but also promotes dignity and well-being for vulnerable individuals. The qualification is recognised by employers and regulatory bodies, making it a valuable addition to any care worker's portfolio. By the end of the course, students will be confident in implementing standard infection control precautions (SICPs) and transmission-based precautions (TBPs) in their workplace.
Key Concepts
Core ideas you must understand for this topic
- →Chain of infection: The six links (infectious agent, reservoir, portal of exit, mode of transmission, portal of entry, susceptible host) that must all be present for an infection to occur. Breaking any link prevents infection.
- →Standard precautions: Basic infection control measures applied to all patients regardless of diagnosis, including hand hygiene, use of PPE, safe handling of sharps, and environmental cleaning.
- →Hand hygiene: The single most important measure to prevent infection. The '5 Moments for Hand Hygiene' (before touching a patient, before clean/aseptic procedure, after body fluid exposure risk, after touching a patient, after touching patient surroundings) must be followed.
- →Personal protective equipment (PPE): Gloves, aprons, masks, and eye protection used to protect staff and patients from infection. Correct donning and doffing procedures are critical to avoid contamination.
- →Waste management: Segregation of clinical waste (e.g., sharps, infectious waste) into colour-coded bins to prevent harm and comply with regulations.

Assessment Criteria
Key criteria assessors look for in your portfolio
- Award credit for demonstrating clear understanding of specific legislation (e.g., Health and Safety at Work Act, COSHH) and how it applies to infection prevention in social care settings.
- Award credit for accurately describing the chain of infection and how own role breaks the chain through standard precautions.
- Award credit for producing a detailed risk assessment identifying potential infection hazards and control measures, tailored to a specific care scenario.
- Award credit for correctly selecting and explaining the use of different types of PPE based on the level of risk and type of exposure.
- Award credit for evidencing consistent application of hand hygiene protocols, including the '5 moments' approach, in practical tasks or simulated observations.
- Award credit for demonstrating an accurate understanding of the chain of infection and how breaking any link prevents transmission, with specific examples relevant to health and social care.
- Award credit for correctly identifying key legislation (e.g., Health and Safety at Work Act 1974, COSHH) and explaining their direct implications for infection control practices.
- Award credit for providing a detailed risk assessment example that identifies hazards, evaluates risks, and proposes proportionate control measures, showing understanding of the hierarchy of controls.
Assessment Guidance
Guidance for achieving higher grades
- 💡In written assessments, always link your answers to specific legislation and employer policies, not just general good practice.
- 💡When providing evidence, include dated reflective accounts or witness testimonies that demonstrate how you applied infection control principles in real work situations.
- 💡For practical observations, verbalise your thought process (e.g., risk assessment, choice of PPE) to show underpinning knowledge, not just the physical task.
- 💡Revise using case studies that illustrate infection outbreaks or near-misses; be prepared to analyse what went wrong and how you would prevent it.
- 💡When answering scenario-based questions, always link your response to relevant legislation and policies (e.g., cite COSHH for hazardous substances, RIDDOR for sharps injuries).
- 💡Use technical terminology accurately: differentiate between cleaning, disinfection, and sterilization, and explain their appropriate applications in different care contexts.
- 💡For assignments requiring demonstration, ensure you follow the correct sequence for donning and doffing PPE, and explain why each step is critical to prevent self-contamination and cross-infection.
- 💡When answering questions about the chain of infection, always name all six links and give a specific example of how to break each one. For instance, breaking the 'mode of transmission' link by using hand hygiene after touching a contaminated surface.
- 💡For questions on PPE, describe the correct order of donning (apron, mask, eye protection, gloves) and doffing (gloves, apron, eye protection, mask) and explain why this order prevents self-contamination.
- 💡Use the '5 Moments for Hand Hygiene' in any scenario-based question. Examiners look for application of this framework to real-life situations, such as before assisting with a dressing change.
Common Mistakes
Common errors to avoid in your coursework
- Confusing infection prevention responsibilities with those of a clinician, underestimating the scope of their own role as a care assistant.
- Failing to recognise that all body fluids (not just blood) are potentially infectious, leading to inconsistent use of PPE.
- Overlooking the importance of environmental cleaning and waste disposal as part of infection control, focusing only on direct personal care.
- Assuming that risk assessments are one-time documents rather than dynamic, continuously reviewed processes.
- Misunderstanding the correct sequence for donning and doffing PPE, increasing contamination risks.
- Confusing the roles of different agencies (e.g., assuming the local authority is responsible for infection control audits in care homes, rather than the registered manager/individual providers).
- Believing that wearing PPE alone is sufficient to prevent infection, overlooking the critical importance of hand hygiene and environmental cleaning.
- Failing to recognize that risk assessments are living documents; learners often describe them as one-off tasks rather than processes that require regular review after incidents or changes in circumstances.
- Misconception: Hand washing with soap and water is always better than alcohol-based hand rub. Correction: Alcohol-based hand rub is more effective against most germs and is preferred when hands are not visibly soiled. Soap and water should be used when hands are dirty or after caring for patients with diarrhoea (e.g., C. difficile).
- Misconception: Wearing gloves means you don't need to wash your hands. Correction: Gloves can have microscopic holes and can become contaminated during removal. Hand hygiene must be performed before putting on gloves and after removing them.
- Misconception: Infection control is only important in hospitals. Correction: Infections can spread in any care setting, including care homes, clinics, and community care. Standard precautions apply everywhere.
