The purpose of these recommended guidelines is to promote safety in the use of power boilers. The term “power boiler” in this Section includes stationary, portable, and traction type boilers, but does not include locomotive and high temperature water boilers, nuclear power plant boilers, heating boilers, pressure vessels, or marine boilers. This Section provides such guidelines to assist those directly responsible for operating, maintaining, and inspecting power boilers. Emphasis has been placed on industrial type boilers because of their extensive use. Guidelines are also provided for operation of auxiliary equipment and appliances that affect the safe and reliable operation of power boilers. Careful application of this Section will help users to comply with applicable regulations within their jurisdictions, while achieving the operational, cost and safety benefits to be gained from the many industry best-practices detailed within these volumes. All changes to this 2013 Edition are incorporated into the appropriate page and each affected area is identified with a designator. Each Section includes a Summary of Changes that lists the material affected by the change, plus the nature of the change. There will no longer be Addenda service for this 2013 Edition or for future Editions. Intended for manufacturers, users, constructors, designers and others concerned with the design, fabrication, assembly, erection, examination, inspection and testing of pressure vessels, plus all potential governing entities.
