cupancy capacity, means of egress and access, signage, re safety
and the need for the following information and quali ers to be

Chapter 6 presents design examples
that are representative of the tornado and
hurricane wind load calculations that may
be required when designing a storm shelter
or safe room.
Design Guide 35 addresses the most
current requirements and considerations
for storm shelter and safe room design. We
