| Intent | Intent 1: To limit the probability of a discontinuous air barrier
system at penetrations through assemblies, which could lead to a loss of airtightness,
which could lead to excessive air infiltration and exfiltration.
Where the air barrier system separates a garage, or suite containing
a garage, from residential space, to limit the probability that gas and fumes
will migrate from the garage into the remainder of the building, which could
lead to the accumulation of gas and fumes and their subsequent ignition by
a nearby ignition source, which could lead to a fire or explosion, which could
lead to harm to persons.
