SafetyQuestion 574 of 700
Concrete trucks need a place to rinse out their chutes on site. What is the BEST practice to protect the environment?
a.Rinse chutes into the nearest storm drain
b.Use a designated, contained concrete washout area that keeps wash water out of drains and soil
c.Rinse onto bare soil at the edge of the lot
d.Let drivers rinse wherever is convenient
Explanation
Concrete wash water is highly alkaline and must be contained in a designated washout with a liner or watertight container so it cannot reach storm drains, waterways, or unprotected ground. Option a discharges pollutants directly to surface water. Options c and d allow caustic runoff to contaminate soil and drains. A contained washout captures the material for proper disposal and keeps the site compliant.
