Infection Control, Safety and Professional Standards
What you must understand
Candidates need standard precautions: hand hygiene, personal protective equipment, environmental cleaning, waste segregation, and safe handling of sharps where applicable. Understand sterilisation versus disinfection versus sanitisation, and which items require which level. Know single-use versus reusable classification, instrument tracking, and reprocessing steps including cleaning before disinfection. Safety includes patch testing, emergency protocols, fire and electrical safety, and incident reporting. Professional standards cover scope of practice, informed consent, confidentiality, and duty of care.
Traps in questions
A common trap is believing alcohol wipes sterilise. They disinfect at best and are ineffective against spores. Another is skipping cleaning before disinfection - residue defeats the process. Questions may test that gloves do not replace hand hygiene, or that jewellery and nail length affect hand hygiene efficacy. Also beware of assuming a signed form satisfies consent if risks were never discussed.
Rule of thumb
Use the "clean, then kill" rule: physical cleaning always precedes disinfection or sterilisation, and only validated processes count.
Worked example
After a microneedling session, reusable implements are cleaned of residue, then reprocessed by a validated method appropriate to their classification, with the cycle logged. Single-use cartridges are discarded into sharps waste immediately.
