The State Industrial Commission is cracking down on those people who install boilers in buildings without notifying the commission so the work can examined by an inspector.

That news came at the same time the commission approved updated rules and regulations regarding the installation and operation of boilers and pressure vessels to conform with requirements of the American Society of Mechanical Engineers.While presenting the new rules to the commission Wednesday, James Parsell, commission safety director, admitted that nobody has been prosecuted for not notifying the commission of a boiler installation and failing to pay an inspection fee.

Parsell said most people are honest, and the majority obey the boiler installation and operation rules and regulations. Commissioner John Florez said if there is a rule it should be enforced, but Commission Chairman Stephen M. Hadley said if an inspector is required to sit in court testifying for one day, his regular inspection work will be delayed.

Florez said one case of a person failing to notify the commission about a boiler installation should be taken through the courts to "let people know we are serious about this rule."

The newly adopted rules will go through the usual state rule-making procedure, and the public can comment on the changes. One of the most important changes calls for inspections of boilers annually rather than biennially under the old regulations.

Parsell said the rules will require added work for his inspectors, and he recently hired another one to help relieve the workload. There are 11,000 boilers in Utah that require inspection. Insurance company inspectors examine 60 percent, and state inspectors look at 40 percent of them.
