Which of the following signs is commonly required in studios to support safety and hygiene policies?

• A. No Smoking sign
• B. Advertising sign
• C. Event schedule sign
• D. Surveillance sign

Answer: (A)

In studio safety and hygiene practices, a No Smoking sign is essential because it directly supports a clean, safe environment. Smoking introduces fire risks around flammable inks, solvents, sanitizers, and alcohol-based products, and smoke can contaminate air and surfaces used during procedures. A visible No Smoking sign reminds everyone to follow the policy, helps enforce it, and aligns with fire and health-code expectations to protect clients and staff.

The other signs don’t address safety and hygiene in the same way: advertising signs are about marketing, event schedule signs relate to operations timing, and surveillance signs deal with monitoring/privacy rather than health and cleanliness standards.
