Is there any rule prohibiting the horizontal exit from annex building to the aircraft hangar in accordance with NFPA 101?
1. So what is the rating on the wall between the two areas?
2 . What type of occupancy/operation in the annex?
3. Maybe a slight problem exiting into a more hazardous area, and discernible route?
I could not find rules prohibiting the horizontal exit from annex building exists in NFPA 101, Section 7.2.4. Subsection __2.2.5 of the occupancy chapters is where horizontal exits are permitted.
It is not uncommon a hanger would have offices along side of the aircraft hanger where the exterior walls of the hanger at not available for the required exits at 150 ft. intervals.
In the 2018 edition of NFPA 101, provisions that apply to aircraft servicing hangars, which are classified as industrial occupancies, see Section 40.6.
Section 42.6 specifies two alternative methods of providing egress from aircraft storage hangars. Based on there are to be not less than two means of egress from each aircraft storage area.
