ANSI/ASSE A10.8-2001American National Standard: Scaffolding Safety Requirements The purpose of this article is to provide background information about the ANSI/ASSE A10.8 Standard. ASSE member interest from the Construction and Mining Practice Specialties continues to be strong in this standard, and scaffolding continues to be a significant safety and health issue addressed by regulatory agencies such as the U.S. Occupational Safety and Health Administration. A new version of the standard was approved in 2001, but most stakeholders do not seem to be aware of this specific new revision. To address this issue we are preparing this overview and article for members of the ASSE Construction and Mining Practice Specialties and for stakeholders of the construction, mining, and demolition industries.
The current cost of the standard is $53.00 and for the cost of the standard SH&E professional would receive: ANSI/ASSE A10.8-2001, Scaffolding Safety Requirements ANSI A10.8-1988, Scaffolding Safety Requirements ANSI A10.8-1977, Scaffolding Safety Requirements ***(Note: These additional historical standards will only be offered as a package until 8/1/2004. After this date there would be an additional cost to purchase these historical documents.) While the older standards are out of date, they continue to serve as valuable historical resource since they are still recognized by the U.S. Occupational safety and Health Administration. This specific announcement contains: Background Links of A10.8 Recognition by OSHA Links Addressing Standards Recognition A10.8 Table of Contents Background
The A10 Accredited Standards Committee is one of the oldest voluntary national consensus standards developing bodies in the United States. It has existed in some form since 1944 and currently has almost fifty accredited standards and projects. For many years the National Safety Council served as secretariat of this committee, but ASSE became the secretariat of this committee during January of 2003. The scope of the A10 ASC remains unchanged and currently is: To write and interpret standards relating to the protection of employees and the public from hazards arising out of or associated with construction and demolition operations The A10.8 Standard has a long history with iterations of the document going back to the 1970s. The standard is recognized by the U.S. Occupational Safety and Health Administration in over two dozen places, and is also referenced by other federal/state government agencies. A Google search of A10.8 yielded almost 1,000 examples of citation/recognition of the standard by the private sector. The A10.8 Standard
The scope of the standard addresses the establishment of safety requirements for the construction, operation, maintenance, and use of scaffolds used in the construction, alteration, demolition, and maintenance of buildings and structures. The standard does not cover permanently installed suspended scaffold systems or aerial platforms. The purpose of the standard is to provide reasonable safety for life and limb of those engaged in occupations requiring the use of scaffolding. There is one significant exception to the standard. In cases of practical difficulties, unnecessary hardships, or new developments, exceptions to the literal requirements may permit the use of other devices or methods, but only when it is clearly indicated by a qualified person that the equivalent protection is thereby secured.
