I have to design a small one story building with openings to all elevations. The occupancy is assembly for less than 300 people. It's a celebration pavilion next to the seashore. The question is if we can avoid to install sprinkler and fire hoses. We have a site with no water supply and all fire protection will need to come from an above ground storage tank. What precautions we can take in order to avoid it. Could we use only fire extinguishers? And what kind of them?
