Chemical hair services (colour, bleach, perms) Risk Assessment Template

Typical hazards & measures

• Client movement during processing — Seat clients comfortably with head/neck support, explain why stillness matters, and set a call-bell for discomfort. Clip foils securely, avoid folding against the scalp, and pause if the client needs to move; recheck placement and timing before resuming.
• Foil heat build-up on scalp — Use thin, even sections and appropriate developer; leave air gaps and avoid hood dryers over dense foil packs. Monitor by touch, remove any hot packet immediately, cool the scalp if needed, and adjust placement or strength to prevent thermal hotspots on future visits.
• Allergic reaction to oxidative dyes (PPD/PTD) — Carry out an allergy alert test with the exact brand, shade and oxidant 48 hrs prior; review history including black henna and severe past reactions. Avoid damaged skin, use barrier at hairline/ears, and keep emergency steps visible; stop and rinse immediately if symptoms appear.
• Occupational asthma from persulfate dust — Use low-dust lighteners, mix gently under local extraction, keep lids on bowls, decant minimal quantities, and avoid vigorous shaking. Offer FFP2/3 to symptomatic staff, rotate tasks, and set up health surveillance with referral pathways for persistent respiratory symptoms.
• Allergic reaction to persulfate lighteners — Screen for asthma or past bleach reactions; choose low-dust powders and mix slowly in ventilated areas. Keep product off skin, use gloves/eye protection, check sensation regularly, and remove immediately if tingling escalates to burning; document batch and timing for traceability.
