QLDers really like sealable containers, for whatever reason. They can be kept in the same area as where disposables are kept - there's actually not much in the regs about it, but one place I worked used cloth and this is exactly what they did, with no problems. It's in Brissy. Get them to contact their OECEC rep and get some advice if they're unsure - I always found they were really helpful with that, and then you can't get in trouble if the advice came out of their mouth in the first place.
