OH1 Indoor Conditions



Intent 1:

To limit the probability that inadequate distance between soil-or-waste pipes and other, nominally horizontal soil-or-waste pipes or nominally horizontal offsets in soil-or-waste stacks that receive high volumes or velocity of discharge, will lead to trap seal failure, which could 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.
