All of the following are classified as equipment used in nail service EXCEPT?

The classification of equipment used in nail services typically includes items that are essential for providing nail care and enhancements. While an abrasive board is indeed a tool used for filing and shaping nails, it is considered a part of the implements rather than equipment. Implements are the tools that are used directly on the client’s nails during the service.

On the other hand, a pedicure chair is specific equipment designed to provide comfort and support during pedicures. A service cushion is used to elevate the client's hand or foot, enhancing both comfort and accessibility during the nail service. A trash container, although it may not be directly involved in the application or enhancement of nails, is still classified as essential equipment because it is necessary for maintaining hygiene and cleanliness in the workspace.

Understanding the difference between implements and equipment is crucial for proper classification in a nail service context. Therefore, the abrasive board stands out as the option that does not belong to the category of equipment used in nail services.
