Infection Control, Sanitation, and Safety Practices
Levels of control
Most questions in this domain reduce to one decision: what does this item or surface require? Sanitation mechanically removes visible soil and lowers microbe counts on nonporous surfaces and on tools that contact only intact skin. Disinfection destroys most pathogens on hard, nonporous implements using an EPA-registered hospital disinfectant - with a tuberculocidal claim when blood or body fluids may be present. Sterilization destroys all microbial life, including spores, and is reserved for items that penetrate skin or contact blood; a barber should not be using such items at all.
Know your organisms
Review cocci, bacilli, and spirilla; viruses (hepatitis, HIV, herpes); fungi (tinea/ringworm); and parasites (pediculosis). Understand the chain of infection and that standard (universal) precautions means treating every client's blood and body fluids as infectious.
Traps
- Calling a 10-minute soak in hospital disinfectant "sterilization."
- Forgetting that porous items - towels, neck strips, wooden handles, honing leather - cannot be disinfected and must be discarded or laundered.
- Skipping the SDS binder; OSHA requires safety data sheets for every chemical in the shop, accessible to employees.
- Mishandling a blood spill: gloves on, service stopped, wound cleaned, area disinfected with an EPA-registered tuberculocidal product (or 1:10 bleach), waste double-bagged, hands washed, incident documented.
- Electrical safety: inspect cords, never immerse clippers, keep water away from outlets.
Rule of thumb
If an item cannot be soaked, sprayed, or wiped with an EPA-registered disinfectant, treat it as single-use. Always honor the full label contact time - never shorten it.
