When filling rinsing draining and cleaning your equipment, what area feature should it have?

• A. A drain with a filter
• B. An outdoor grassy area
• C. A wash pad wash rack or concrete apron with a well designed sump to catch contaminated water
• D. A covered sink

Answer: (C)

The key idea is to have a containment area for rinse and wash water so contaminated runoff doesn’t soak into soil or flow into waterways. A wash pad, wash rack, or concrete apron designed with a sump to catch contaminated water provides that containment, capturing the rinsate so it can be collected and disposed of or treated properly. This setup prevents environmental contamination and helps you manage waste responsibly.

A drain with a filter isn’t enough because filters can clog and contaminated water can still bypass the filtration or overwhelm the system. An outdoor grassy area risks soil and groundwater contamination from rinsate runoff. A covered sink may not be sized or equipped to handle the volumes of wash water and typically lacks a proper sump to hold contaminated liquid for disposal.
