Intent 1:
To exempt certain services from the application
of Sentence 5.6.2.1.(1), which would otherwise require that
services be shut off or disconnected, if certain measures are taken,
on the basis that these services are needed during excavation.
This [the measures] is to limit the probability that:
- services will be operated in an unsafe manner, which
could lead to a fire or explosion, which could lead to harm to persons,
- services will be physically damaged [e.g. damage to
fuel lines causing an unwanted leak], which could lead to a fire or
explosion, which could lead to harm to persons,
- supporting structure for the services will fail, which
could lead to damage to the services [e.g. fuel pipe failure or exposure
of electrical lines], which could lead to a fire or explosion, which
could lead to harm to persons, and
- water services will be physically damaged, which could
lead to an inadequate water supply to fire suppression systems [sprinklers,
standpipes, yard hydrants] in a fire situation, which could lead to
the fire not being suppressed or controlled, which could lead to the
spread of fire, which could lead to harm to persons.
