22、f the A10 Committee standards. If these standards are adopted for governmental use, the reference of other national codes or standards in individual volumes may be changed to refer to the corresponding regulations. Revisions: The A10 Committee welcomes proposals for revisions to this standard. Revis
23、ions are made to the standard periodically (usually five years from the date of the standard) to incorporate changes that appear necessary or desirable, as demonstrated by experience gained from the application of the standard. Proposals should be as specific as possible, citing the relevant section

26、y interpretation of this standard.

Appendices: Appendices are included in most standards to provide the user with additi
27、onal information related to the subject of the standard. Appendices are not part of the approved standard. Checklists: Checklists included in A10 standards may be copied and used in non- commercial settings only. Committee Meetings: The A10 Committee meets twice a year. Persons wishing to attend a m
28、eeting should contact the Secretariat for information. Standard Approval: This standard was processed and approved for submittal to ANSI by the American National Standards Committee on Safety in Construction and Demolition Operations, A10.
