APPLICATION:
Access to, and protection of, odour removal equipment
of the adsorption type, in heating, ventilating and air-conditioning systems,
for air duct systems, in buildings described in Sentence
1.3.3.2.(1) of Division A.
This also applies to buildings to which Part 9 applies [see Sentence

To limit the probability that dust will accumulate on the
adsorbing surface, which could lead to the equipment losing its capacity to
remove odours, which could lead to negative effects on the air quality of
indoor spaces, which could lead to harm to persons.
