OS3 Safety in Use



Intent 1:

To waive the requirement for a fire separation between a dwelling unit and an attached garage as stated in Sentence on the basis that sufficient conditions are in place to minimize the threat posed by exposure to gas and vehicle exhaust fumes to the occupants to the dwelling unit, or to the occupants in other dwelling units.

This is to limit the probability that gas and fumes will migrate from the garage into the dwelling unit, which could lead to their accumulation to levels that pose a risk to human health from short-term exposure, which could lead to harm to persons.
