The back room with no extraction

The breaches are: no local exhaust ventilation in the mixing room; decanting chemicals into unlabelled food-style bottles; no accessible safety data sheets; inadequate skin protection and a junior with visible dermatitis; overflowing clinical waste; and applying 40-volume peroxide to a client who disclosed scalp sensitivity without a clear patch-test record. I would rank them by likelihood and severity. First is the 40-volume scalp application: a strong oxidant on a sensitive scalp can cause a chemical burn, and the client is already in the chair. Second is the unlabelled bottles plus missing SDS: staff cannot identify incompatibilities, first-aid measures or spill procedures, and an accidental mix could release heat or fumes. Third is the junior's dermatitis, because cracked skin increases absorption and can become a long-term occupational skin disease. Fourth is the waste overflow, which creates a contamination and disposal risk. Fifth is ventilation, which affects everyone over time. The ranking matters because the salon cannot fix everything at once, but it must stop the highest-consequence exposure immediately.

Immediate controls: stop the 40-volume scalp application, check the scalp, and either reschedule or use a lower-strength product away from the scalp after a proper consultation; remove the unlabelled bottles from use and label or dispose of them as unknown chemicals; put gloves on the junior and move her away from mixing until her skin is assessed; open the door and window if safe, and stop mixing in the windowless room; arrange clinical waste collection. The senior stylist or manager on duty should own the client-safety decision; the owner should authorise chemical disposal and waste collection. Longer-term controls: install extraction or a dedicated ventilated mixing area; ban decanting and use original labelled containers; keep SDS accessible in the salon; introduce a chemical inventory and risk assessment; provide nitrile gloves and hand-care training; set up health surveillance and GP referral for the junior; schedule waste collections; train all staff on spill and exposure procedures. Responsibility should be named, not left to 'everyone': owner for premises and insurance, manager for daily checks, each stylist for their own PPE and client screening.

The junior's red, cracked knuckles and sneezing suggest occupational dermatitis or sensitisation, not just dry hands. I would remove her from wet work, bleach and colour mixing immediately, encourage her to see her GP, and record the symptoms and exposure in the salon's accident/incident book. I would review her tasks, provide suitable gloves, and consider referral to occupational health if symptoms persist. Under Irish safety and health legislation, the employer must assess risks and protect employees, and dermatitis is a recognised occupational skin disease, so this is not a personal matter to ignore. The unlabelled bottles should be treated as unknown hazardous chemicals: do not use them, do not pour them down the sink, and dispose of them through a licensed waste contractor. I would inform the owner, check the salon insurance position, and introduce a written labelling and storage procedure. Records of the exposure, the actions taken and the client outcome should be kept. Insurance depends on demonstrating safe systems, competent staff and traceable products; unlabelled chemicals and untreated dermatitis undermine all three.
