The failed autoclave and fourteen Saturday clients
On Friday evening the salon's autoclave prints a 'cycle failed' error. The senior therapist runs a biological indicator spore test, which is positive 24 hours later. It is now Saturday 08:30. Fourteen clients are booked for waxing, lash tinting and facial extractions between 09:00 and 17:00. Six of those appointments involve reusable metal extraction tools, tweezers and comedone extractors. The salon also has single-use wooden spatulas, disposable needles, 70% isopropyl alcohol, chlorhexidine 2% and a UV cabinet. The salon owner is away and the senior therapist suggests 'soaking everything in alcohol for 10 minutes and carrying on; it's only skin.' Two staff members are newly qualified and one is pregnant. A client due at 09:15 has had cold sores in the past.
1. Is the senior therapist's proposal to soak the tools in 70% isopropyl alcohol for 10 minutes and continue safe? Justify your answer microbiologically.
Read the worked answer
No. A positive biological indicator means the autoclave did not achieve sterilisation; bacterial spores survived. Alcohol 70% is a disinfectant, not a sterilant. It is active against many vegetative bacteria and some enveloped viruses, but it is not sporicidal, it evaporates quickly, and it does not reliably penetrate blood or organic matter. Chlorhexidine 2% is an antiseptic with poor activity against spores, mycobacteria and non-enveloped viruses. A UV cabinet is for storage, not sterilisation. Reusable extraction tools that may contact blood or serum are critical items and must be sterile. Soaking them in alcohol would create false assurance and could transmit bloodborne viruses such as hepatitis B, hepatitis C and HIV. The correct response is to stop using the autoclave, quarantine the affected instruments, and use validated single-use sterile alternatives only if they are appropriate and in date. The senior therapist's 'it's only skin' comment ignores that skin is a vascular, breakable barrier.
2. What should happen to the day's bookings and the reusable equipment?
Read the worked answer
Treat the autoclave as out of service: label it, remove the plug or lock the door, and record the failed cycle and positive spore test. Quarantine every instrument processed since the last passed validation, not just yesterday's load. Do not use them on clients. Repackage and reprocess only after the autoclave has been serviced, revalidated and passed a repeat biological indicator. For today, triage bookings: waxing can proceed with single-use spatulas and disposable strips where possible; tweezers that may contact blood should not be used. Facial extractions should be postponed unless single-use sterile extractors are available. Lash tinting can proceed with patch-tested products and disposable applicators. Reschedule the client with a history of cold sores if she has an active lesion; herpes simplex is a contraindication to facial waxing/extractions near the area. Contact affected clients honestly, offer rebooking, and do not charge for postponed treatments. Pregnant staff should not be exposed to bloodborne risks; allocate non-invasive tasks.
3. What documentation, staff communication and follow-up are required?
Read the worked answer
Complete an incident report the same day: autoclave ID, cycle number, spore test result, date, action taken, instruments quarantined and clients affected. Update the equipment log and keep the positive test as evidence. Hold a brief staff huddle: explain why alcohol is not a substitute, who is authorised to release instruments, and the salon's standard precautions. Newly qualified staff need direct supervision, not reassurance that 'it's fine'. Check hepatitis B vaccination status and offer occupational health advice for any staff member with a sharps exposure. Inform the owner and, if your insurer or local infection-control guidance requires it, report the sterilisation failure. Review the autoclave contract, validation schedule and loan equipment. After revalidation, run a test cycle before treating clients. Audit single-use stock and create a downtime kit. Follow up with any client who may have been treated with a quarantined instrument and document the advice given.
