The boiler regulations enacted in 1982 also include the requirement for inspection of domestic hot water heaters located in city, county or state facilities. This change was the result of the tragic deaths of five children and one teacher who were killed when a water heater exploded in the Star Elementary School cafeteria in Oklahoma City. In all, the Oklahoma Department of Labor has jurisdiction to inspect almost 20,000 hot water heaters. Of these, approximately 9,000 hot water heaters are inspected annually. Amusement Rides Safety regulations were passed in 1982 requiring the inspection of amusement rides operating within the state.
Rides located in permanent parks require inspection at least once each year.
All other rides require inspection each time they are moved and set up. Approximately 1500 rides are inspected each year. Approximately 50 reviews are conducted each year. In 1978, regulations were enacted requiring that those who weld on piping systems constructed to certain piping codes be tested by a weld test facility approved by the Oklahoma Department of Labor. Welders who pass are issued a State of Oklahoma welder's card.
