A strata title property has a number of enclosed stair wells, each servicing several flats on several levels. The ground floor doors are keyed from the outside and do not require a key from the inside. The doors are self-closing. Some are made of timber, and some are nearly all glass, in panels. The ground floor doors and the stair wells are the only way into the flats. The OC manager has had signs put up that the ground floor doors are fire doors and must be kept shut. As far as I can see the doors are ordinary timber hollow construction, if heavy. Most door are wide, which would account for the weight. It may be that a fire door cannot be determined from the outside. It seems that fire doors are only used on fire stairs. That is, if it's not a fire stair there can be no fire door. There's a morass of information about this, including BCA, fire brigade and many local sources. I can't find brief definitive information about this. I think the OC manager has goofed, and may have to pay for this. I've given some advice from the fire brigade to evidence the aforementioned goofing, and the OC manager is digging in. 1 Is the stair as described above a fire stair? 2 Are glass doors allowed on fire stairs? 3 Is there any easy way to determine if a door is made to be a fire door? 4 Could websites backing up the above be provided? 5 Is there anything else that would add to the above? Many thanks.
