Information Collection: Safety Defects; Examination, Correction and Records

Sections 56.13015 and 57.13015 require compressed-air receivers and other unfired pressure vessels to be inspected by inspectors holding a valid National Board Commission and in accordance with the applicable chapters of the National Board Inspection Code, a Manual for Boiler and Pressure Vessels Inspectors, 1979. Safety defects found on compressed-air receivers and other unfired pressure vessels have caused injuries and fatalities in the mining industry. Records of inspections must be kept in accordance with the requirements of the National Board Inspection Code and the records must be made available to the Secretary or an authorized representative. Sections 56.13030 and 57.13030 require that fired pressure vessels (boilers) must be equipped with water level gauges, pressure gauges, automatic pressure-relief valves, blowdown piping, and other safety devices approved by the American Society of Mechanical Engineers (ASME) to protect against hazards from overpressure, flameouts, fuel interruptions, and low water level.
