4.9.4.2.(1)

Intent 1:

To exempt certain rooms and buildings from the application of Sentence 4.9.3.1.(1), which would otherwise require explosion venting, if certain measures are taken.

This is to limit the probability that an explosion involving the processing equipment will:

• occur, which could lead to harm to nearby persons, and
• lead to damage to the equipment, which could lead to harm to nearby persons.
