Intent 1:
To exempt liquids with a lower flammability risk
from the application of Sentence 4.6.8.6.(1), which would otherwise
require the engines to be turned off, if certain measures are taken
[a minimum distance is maintained].
These measures
are to limit the probability that:
- the vapour from nearby Class I liquid dispensers will
be ignited by the engine, which could lead to harm to persons, and
- the vapour from nearby Class I liquid dispensers will
be drawn into the engine's intake system, which could lead to over-revving
or overheating of the engine, which could lead to a fire, which could
lead to harm to persons.
