Waste connections are not required for _____.

Emergency eyewash stations are designed specifically for safety and first aid purposes, providing immediate flushing of the eyes in case of exposure to harmful materials. While they are associated with plumbing systems, they do not require traditional waste connections like sinks or other fixtures that involve typical drainage. Instead, eyewash stations can be plumbed to a water supply but may drain into a separate containment system, such as a floor sink or a floor drain, which allows for safe management of the used water without the need for a direct waste connection.

In contrast, laundry trays, automatic clothes washers, and floor drains all typically require waste connections to properly dispose of wastewater, making them different from emergency eyewash stations. This distinction highlights the unique function of eyewash stations as safety devices rather than standard plumbing fixtures.
