16、eword (This Foreword is not a part of American National Standard A10.28-2011). This standard is one of a series of safety standards that have been formulated by the Accredited Standards Committee on Safety in Construction and Demolition Operations, A10. It is expected that the standards in the A10 s
17、eries will find a major application in industry, serving as a guide to contractors, labor, and equipment manufacturers. For the convenience of users, a list of existing and proposed standards in the A10 series for Safety Requirements in Construction and Demolition Operations follows. A10.1 Pre-Plann

26、,-A10.47 Highway Construction Safety A10.48 Communication Tower Erection (under development) A10.49 Control of Health Hazards (under development) One purpose of these standards is to serve as guides to governmental authorities having jurisdiction over subjects within the scope of the A10 Committee s
27、tandards. 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. Revisions are made to the
28、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 number(s), the propo
29、sed wording, and the reason for the proposal. Pertinent documentation would enable the A10 Committee to process the changes in a more timely manner. Interpretations: Upon a request in writing to the Secretariat, the A10 Committee will render an interpretation of any requirement of the standard. The
30、request for interpretation should be clear, citing the relevant section number(s) and phrased as a request for a clarification of a specific requirement. Oral interpretations are not provided. No one but the A10 Committee (through the A10 Secretariat) is authorized to provide any interpretation of t
31、his standard. Approval: Neither the A10 Committee nor American National Standards Institute (ANSI) “approves,“ “certifies,“ “rates,“ or “endorses“ any item, construction, proprietary device, or activity. Appendices: Appendices are included in most standards to provide the user with additional inform
32、ation related to the subject of the standard. Appendices are not part of the approved standard. Committee Meetings: The A10 Committee meets twice a year. Persons wishing to attend a meeting should contact the Secretariat for information. Standard Approval: This standard was processed and approved fo
33、r submittal to ANSI by the American National Standards Committee on Safety in Construction and Demolition Operations, A10. Approval of the standard does not necessarily imply (nor is it required) that all Committee members voted for its approval. At the time this standard was approved, the A10 Commi

41、n. Provisions shall be made for anchoring fall protection equipment, such as lanyards from a height as high or higher than the dorsal D-ring to limit free fall distance. 5.8 Grab Rail. A recessed grab rail shall be provided all the way around the inside of the suspended work platform to minimize han
42、d exposure to minimize exposure to surfaces or obstructions that could contact the outside of the platform. 5.9 Stability. The suspension system shall minimize tipping of the platform due to movement of the personnel using the platform. Movement in any direction shall be limited to keep the platform
43、 from swinging. Hoisting of personnel on the platform shall be performed in a slow, controlled, cautious manner with no sudden movements of the crane, derrick, or platform. 5.10 Access Height.

SUSPENDED WORK PLATFORM TESTING AND INSPECTION 7.1 Frequency of Inspection. The platform and rigging shall be at a minimum inspected daily by a competent person prior to be
46、ing used. 7.2 Proof Testing. At each new set-up location, prior to hoisting employees in the suspended work platform, the platform and rigging shall be proof-tested to 150 percent of the platforms rated capacity.

After proof testing any deficiencies revealed during an inspection by the qualified person shall be corrected and another proof test shall be conducted. A dated, signed copy of the proof test shall be maintained at the jobsite. 7.3 Trial Run. Immediately prior to placing personnel in the platform, a trial run shall be made by the operator with the suspended platform from the ground to all proposed work elevations to ascertain that: 1) the boom configuration and load lines are adequate; 2) no interferences exist
