The middle of the twentieth century saw a wave of innovation: Radial tires, the polio vaccine, solar cells, computer hard disks, color television, Velcro, the first pacemaker. Less touted, but equally ubiquitous, were rubberized synthetic floors. Their low-maintenance durability and modern finishes saw them widely installed in schools, hospitals, nursing homes, community centers, and other public spaces. Unlike their groundbreaking counterparts, however, some of these synthetic floors did not continue to benefit the populace far into the future. In fact, the years have turned what was once revolutionary into a potentially dangerous environmental health hazard found in today’s older schools, health facilities, and commercial and municipal buildings. Insurance Restoration Specialists, Inc. (IRS) of Monroe, New Jersey, recently sponsored a seminar to educate New Jersey School Board Association (NJSBA) members about the dangers lurking under school gym floors.
