Which item is exempt from waste connections in plumbing installations?

Emergency eyewash stations are considered to be exempt from standard waste connections in plumbing installations due to their specific purpose and design. These stations are primarily intended for immediate use in the event of exposure to hazardous substances, providing a critical safety function. Because they are designed for rapid flushing and decontamination, they can be engineered to operate effectively without requiring a conventional waste connection that would typically be employed for more permanent plumbing fixtures.

This exemption is important in ensuring compliance with health and safety regulations, particularly in environments where hazardous materials are present, allowing for quick and efficient decontamination without the complications that traditional waste systems might introduce.

Other items listed, such as floor sinks, lavatories, and showers, are integral components of plumbing systems and are routinely connected to waste systems to properly dispose of wastewater, highlighting the unique role that emergency eyewash stations play in safety and compliance.
