When two exits are required, what is the minimum separation distance between them in a non-sprinklered building?

Answer: One-half the diagonal of the space

What is the maximum travel distance to an exit in a sprinklered business occupancy?

Answer: 300 feet

Sprinklered business occupancies typically allow up to 300 feet of exit travel distance.
