Never place implements __________.

The correct answer emphasizes the critical importance of hygiene and safety in the practice of nail technology. Never placing implements in your mouth is essential because doing so can introduce harmful bacteria or pathogens into your body, which may lead to serious infections or health issues. The mouth is a gateway to the body and is rich in bacteria, making this action particularly dangerous for both the nail technician and the client.

Maintaining a high standard of cleanliness and safety is fundamental in the nail care industry, as it not only protects the technician but also ensures that clients receive services in a hygienic environment. It's crucial for nail technicians to adhere strictly to safety protocols to prevent contamination and uphold professional standards in their work.
