Look around your laboratory and you’re likely to see many sinks and drains. In most cases, sinks and drains are connected to an on site treatment system or a public treatment plant. To prevent dangerous chemical reactions (ex. generation of toxic gases), damage to the plumbing system, or interference with the operation of the treatment plant or system, discharges to a sink or drain must be strictly controlled.

Proceed with this section of the EVC to learn about the requirements associated with sinks and drains.
