Day by day, due to the augmentation of number of cars using in cities; shopping malls, city hospitals and some of assembly buildings prefer car stackers instead of conventional parking areas. In NFPA13, it is indicated that parking areas equipped with car stackers shall be considered as Extra Hazard Group 2.
Do we have a chance to reduce the hazard group via providing extra precautions such as additional sidewall heads between platforms etc.? Is there any further explanation regarding car stackers in other codes?
Thanks in advance for your replies.
