What is a 'barrier technique' and give two examples in a salon?

• A. Using disposable gloves or single-use liners to prevent cross-contamination; examples: glove usage, barrier covers on surfaces.
• B. Cleaning tools with water.
• C. Using shared towels.
• D. Ignoring PPE.

Answer: (A)

Barrier technique means using protective shields to stop cross‑contamination in a salon. These shields create a physical barrier between clients, tools, and work surfaces to keep microbes from moving between them.

Two practical examples are wearing disposable gloves and using single‑use liners. Gloves create a barrier between the stylist’s hands and clients or contaminated tools, while single‑use liners protect surfaces and tools by providing a fresh, clean layer that’s discarded after each client. Another common example is barrier covers on surfaces like shampoo bowls, countertops, and chair arms—these covers stay with one client and are disposed of after use, preventing contaminants from sticking to reusable surfaces.

These approaches work because they keep potential contaminants away from clients and equipment, reducing the risk of cross‑contamination. Other options fail to maintain a protective shield during service or encourage sharing of contaminated items, which goes against the purpose of barrier techniques.
