ANSI/ASSE A10.8-2011 Safety Requirements for Scaffolding
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.
