Sentence 3.3.5.8.(2)

Intent 1:

To limit the probability that vapours will migrate into other areas of a building, which could lead to the accumulation of the vapours in sufficient quantity to form an ignitable mixture, which could lead to the ignition of the vapours from a nearby ignition source, which could lead to harm to persons.

Intent 2:

To limit the probability that vapours will accumulate in sufficient quantity to form an ignitable mixture, which could lead to the ignition of the vapours from a nearby ignition source, which could lead to harm to persons.

Intent 3:

To exempt canopies that are open on not less than 75% of their perimeter from the requirements of Sentence 3.3.5.8.(2) and permit fuel-dispensing operations inside a building, on the basis that the building design provides direct ventilation to the outdoors, thus limiting the probability that vapours will accumulate to ignitable concentrations or migrate to other parts of the building.
