Chapter 4, Subchapter 7, Article 14, Section 3474(m) and Article 90, Section 4884(c)
Update of ANSI/ASME References for Slings and Cranes
INITIAL STATEMENT OF REASONS
Subsection (m) specifically addresses wire rope and wire rope slings in terms of the manufacturers' ratings which are to be available for inspection by the Division and minimum design safety factors of at least 5 for running in light load use. The regulation states that if there are no ratings available, employers are to refer to the American National Safety standard ANSI B30.9–1971 tables. The regulation also addresses use of wire rope with safety factors less than 5 under special conditions (e.g. where found to be impracticable, where specialized equipment is used, etc.)
A revision is proposed for subsection (m)(1) to amend the reference to ANSI B30.9–1971 by updating it to ANSI/ASME B30.9–1996 standard for slings.
The proposed revision will merely clarify to the employer that when it is necessary to refer to the ANSI/ASME wire rope and wire rope sling rating tables, the tables contained in the 1996 B30.9 standard shall be used. The proposal may result in some employers having to check the performance specifications of their wire rope/slings equipment in comparison to the new tables or contact the manufacturer to ensure the proper rating table is available for inspection.
Section 4884. Scope.
This section establishes the application of Group 13 safety orders to derricks, cranes, and boom-type excavators. The scope statement contains specific requirements that the design of cranes, derricks, etc. is to be in conformance with national consensus standards (i.e. ANSI, ASME B30 Standards), testing and maintenance, or alternative designs by a registered engineer, and in conformance to Title 8, Electrical Safety Order regulations for electrically powered cranes.
Revisions are proposed in subsection (c)(1) to include a new designation of subsection (c)(1)(A) to address older equipment and conformance to the national consensus standards currently listed for the design, construction and installation of various types of cranes and derricks. Subsection (c)(1)(A) would specify cranes and derricks placed in service after September 28, 1986 through October 1, 1998 are to comply with either the older or current editions of the ANSI/ASME standards depending on the type of crane or derrick. The phrase "placed in service before January 1, 1995" which follows the reference to the ANSI/ASME B30.6–1977 standard is proposed for deletion. The proposed revisions will only clarify to the employer which ANSI/ASME standards the particular crane or derrick shall conform to.
A new subsection (c)(1)(B) would require cranes and derricks placed in service after October 1, 1998 (proposals anticipated effective date) to be provided with a label, plate or marking certifying that the crane/derrick conforms to the current applicable ANSI/ASME B30 Standard. Further revisions are proposed to delete subsection (c)(3) which specifies an effective date after which all derricks placed in service are to conform to the ASME B30.6-1990 standard.
The proposed revisions in conjunction with the previous revisions in subsection (c)(1) will have no effect other than to clarify to the employer that newer cranes and derricks are to conform to the most recent ANSI/ASME crane and derrick standards. Where the equipment is not already labeled or marked as required, the employer may need to acquire from the manufacturer the necessary ANSI/ASME information. Using this information, the required identification label, plate or appropriate marking can be provided on the crane or derrick.
The deletion of subsection (c)(3) will have no effect other than deleting repetitive language as a result of the proposed language in the new subsection (c)(1)(B).
