Intent 1:
To limit the probability that:
- vapour from a tank vehicle will accumulate in sufficient
quantity to form an ignitable mixture, which could lead to the ignition
of the vapour from a nearby ignition source, which could lead to harm
to persons,
- a fire involving a tank vehicle will not be suppressed
or controlled, which could lead to the spread of fire to the building,
which could lead to harm to persons,
- a spill of liquid from a tank vehicle will not be contained
or controlled, which could lead to the spread of liquid outside of
the spill area, which could lead to the ignition of the vapour from
a nearby ignition source, which could lead to harm to persons, and
- ignition sources near a tank vehicle will not be minimized,
which could lead to the ignition of vapour from a nearby ignition
source, which could lead to harm to persons.
