Hydrostatic Testing Precautions

Hydrostatic Testing Precautions 1. When performing or witnessing any hydrostatic test, only properly instructed and qualified personnel should actually perform the test. 2. Protective barriers or pits should surround or enclose the object being tested. 3. No personnel should be in the immediate vicinity of the object being tested while pressure is being raised or is above the allowable working pressure. 4. No vessel shall be left unattended while pressure is being raised and no vessel under pressure (hydrostatic) shall be left overnight in a heated area unless it is equipped with a pressure relief device. 5. For water temperature and high pressure incrementation procedure, it is recommended that reference be made to the proper engineering manuals. 6. Only qualified inspectors shall check the object under hydrostatic test, and then only after the pressure has been reduced to the approved allowable working pressure, for any deformation, tightness, distress or integrity. 7. When strain gauge readings are necessary, it is recommended that remote reading and/or recording tape be used. 8. Glass lined or concrete lined pressure vessels shall not be hydrostatically tested in excess of their allowable working pressure, as indicated on the stamping or manufacturer's data report. a. Petition b. Petition: For the modification of any of these rules, the following shall be the method of procedure. c. Any employer or employee, or other person interested or affected by such rules may petition for a hearing on the reasonableness of such rules by filing a petition with the Technical Advisory Committee of Boiler and Pressure Vessel Safety, setting forth the rule or rules upon which a change is desired and the reasons for said change. d. Upon the receipt of a petition, the Technical Advisory Committee will determine its merits and if a hearing is necessary, notice of time and place will be given to the petitioner and to such other persons as the State Board of Health may find directly interested.
