Two illustrations depict trusses for fire tank roofs sloped less than 30 degrees. The left illustration shows a large gap between trusses and no cross-sectional trusses, suggesting the roof cannot support a 25 lb/ft² live load. The designer’s notes in the right illustration present trusses designed to support a "20 PSF" live load. Neither design meets NFPA 22 compliance as they fail to support the required live load.
