If you want you can use 21. (1) (g), I would say this can generally be addressed either by 220.127.116.11. or 18.104.22.168. (2), otherwise using (f) can work.
22.214.171.124. – This definitely is a hazardous activity which, more than likely, is not designed for (need to see the paper work showing the laundry facilities being in the exit) and by the sounds of it the Chief Fire Official has not approved of this.
126.96.36.199. (2) – As the building is 3 storeys, it sounds like this is a required exit, but regardless I would say energized appliances (especially clothes in a dryer) is a combustible material which is not allow to be in a means of egress unless designed for.
For a 9.5 building, I would use 188.8.131.52. (1) as the exit stairway is not separated from the remainder of the building (laundry facilities).
