What is required for storage of caustic or harmful substances in the salon?

In a salon setting, the safety and well-being of clients and staff are paramount. When it comes to the storage of caustic or harmful substances, it is essential that these materials be labeled clearly and kept out of reach of clients. This protocol ensures that individuals who may not be aware of the dangers associated with these substances do not accidentally come into contact with them. Proper labeling alerts staff to any risks and promotes responsible handling. Additionally, storing these substances in an area that is inaccessible to clients minimizes the risk of accidents, injuries, or exposure to potentially harmful chemicals.

While the other options suggest various storage methods, they either compromise safety or do not follow established safety protocols necessary for handling hazardous materials in a professional environment.
