C/AS2 has a restriction within the definition of risk group WB - “Factories, processing and manufacturing plants (excluding foamed plastics)…”
I find the intent of this comment unclear. My default interpretation is that this is meant to exclude the production of foamed plastics as a material or where raw product is processed. In that case the building may fall into risk group WS or required another compliance approach such as C/VM2. The definition of foamed plastics is quite broad in terms of the composition of the material and does not give any consideration to any other treatments or fire retarding properties.
What about a factory used to construct prefabricated buildings where SIP panel with EPS core (fire retarding type) is used as a component in the production? I am dealing with this scenario at the moment where the building otherwise fits neatly within risk group WB.
I would appreciate hearing from anyone that has any experience or thoughts on this issue.
