Acrylic and polycarbonate domes can fail without warning under people and maintenance loads, becoming brittle with age and possibly causing serious injury and death. Workers may stand on roof domes to carry out maintenance, for repairs or for painting. People may accidently fall on roof domes and there is a high likelihood that people will walk or sit on them in flat roof areas that people use for recreational purposes.
