1-4 PVHO AND PVHO SYSTEMS DOCUMENTATION
The owner shall be responsible for maintaining the following documentation for the service life of PVHOs and PVFIO systems:
(a) documentation required by ASME PVHO-1, Section 1, General Requirements
(b) documentation genera ted during inspection, maintenance, repairs, and modifications
(c) documentation related to operational procedures and manuals
1-5 OWNER’S MANUAl.
1-5.1 General
An Owner’s Manual is required for each PVHO. It shall contain adequate information to safely operate and maintain the PVHO, its systems, and associated equipment. The owner shall be responsible for maintaining the manuaL
1-5.2 Component Description
The Owner’s Manual shall include the following:
(a) operating procedures that provide sufficient information to operate the equipment in a safe manner, including
(1) an overview of the PVHO and its systems
(2) procedures to operate the PVHO and its systems
(3) emergency procedures
(b) engineering drawings and schematics necessary for the operation and maintenance of PVHO systems.
(c) systems description that includes an overview and functional description of each system.
(d) equipment documentation that includes electrical and mechanical system descriptions, maintenance requirements, and operating instructions for components and equipment used. This may include collection of vendor-supplied data; supplier-recommended maintenance procedures; and designer-, fabricator-, or manufacturer-supplicd data.
The manual shall be kept current, documenting system changes, equipment updates, and the addition or deletion of procedures, and including vendor-supplied documentation, and shall meet or exceed the requirements of applicable jurisdictional authorities.
2-5 CATtGORIES OF DAMAGE
2-5.1 Superficial (Does Not Require Action)
Damage or a scratch that is superficial in nature (i.e., it affects only the optical clarity of the window and/or is below the significant dimensions set forth in Tables 2-4.1-2 through 241-4) shall require no action on the part of the user other than the logging of the condition on the inspection documents at the time of the discovery of the condition, and continued monitoring thereafter.
2-5.2 Significant (Requires Action)
Damage that is not superficial (i.e., it exceeds the significant dimensions set forth in Tables 24.1-2 through 2-4.14) shall require that the user red tag the window and either repair or replace it. The condition shall be logged on the inspection documents at the time of the discovery of the condition.
2-5.3 Nonrepairable (Requires Replacement)
Whether or not a window is repairable depends, in part, on the thickness; that is, as indicated in ASME LWHO-l Form VP-2, Acrylic Window Design Certification, for the window in question, can the repair be accomplished with the final thickness actual still equal to. or greater than, the thickness required. As the other consideration is ctt, it might appear that a window whose service Life has already exceeded its design life should simply be discarded.
Replacement windows shall meet the requirements for PVHO windows as described in Section 2 of ASME PVHO-1 (i.e., materials, manufacturing processes, quality assurance, material testing, pressure testing, inspection, and certification). Replacement windows shall have all necessary l’VHO certifications (design, manufacture, and pressure test).
2-6 REPAIR OF DAMAGED PVHO WINDOWS
2-6.1 GeneraL
Windows with minor flaws or blemishes may be repaired by the elimination of the flaw, blemish, or chip. Windows with minor flaws or blemishes may be repaired by hand polishing by the user or his agent. Severely damaged windows shall be repaired only by a party having a Quality Assurance Program that meets the requirements set forth in Mandatory Appendix III.
