Procedures are suggested that may be helpful to those responsible for the operation and maintenance of school buildings and gymnasiums. Most schools with gymnasiums utilize them for both instructional and sports purposes. Maintenance of the multipurpose gym are discussed under four subject areas--(1) floors, (2) lighting, (3) sanitation, and (4) safety. A renovation procedure to be used if a gymnasium floor is slightly warped or is in need of complete renovation is included. Lighting systems must be considered in terms of quality of illumination, replacement and cleaning. Specific attention must be given to the sanitary maintenance of floors, shower stall, water closets, urinals, lavatories and drinking fountains auxiliary to a gymnasium. Brief mention is made of the maintenance functions that might prevent falls and those that contribute to safe, orderly evacuation in case of fire or an explosion. (RK)
