There are i two options for construction of this corridor: ' � � 1. Construct the access corridor with 1-hr fire ratings for the wall and ceiling. Doors -- �, must be rated 20 min. Also, windows be fire rated and cannot exceed 25 percent �= � of the area of the walls. ' — i I i 2. Install a direct means of egress from each classroom. This will negate all of the I � i bove requirements. Ii I have attached the pertinent sections of the standard building code and the life safety , i code for your information.
