  1. OH1

Objective

OH1 Indoor Conditions

Attribution

Intent

Intent 1:

To exempt traps from the requirement of Sentence 2.5.1.1.(1) for a vent pipe because storm drainage systems are inherently vented.

This is to limit the probability that a direct connection between floor drains that are not vented and storm drainage systems will lead to the entry of sewer gases into occupied space, which could lead to negative effects on indoor air quality, which could lead to harm to persons.
