Intent 2:

To limit the probability that combustible or reactive deposits will accumulate, which could lead to obstruction of the ventilation system and reduction of its exhaust capacity, which could lead to an explosive atmosphere, which in the presence of a source of ignition could lead to a fire or explosion, which could lead to harm to persons.

Intent 3:

To limit the probability that combustible or reactive deposits will accumulate on the blades of the exhaust fan, which could lead to its misalignment or improper operation, which could lead to the generation of sparks or heat and the ignition of deposits or explosive vapours or mists, which could lead to a fire or explosion, which could lead to harm to persons.
