[Laundry chute fire door requirement?]

Thanks!

[Laundry chute fire door requirement?]

Hope someone can help please. Am thinking of installing a laundry chute from a first floor laundry room to a ground floor laundry room, both laundry rooms will have fire rated doors.  Does the chute have to have its own fire rated door too? If so: does this apply on both floors?  Would putting a fire rated door on the cupboard it is accessed from be adequate.  Upstairs the cupboard would be only for laundry chute acces.  Downstairs it is a large cupboard with water tanks, pump and electric meter and consumer boards, but with plenty of room for a large basket/bag to catch all laundry.  It seemed easy until I started looking at possible regulation pitfalls!
