ANSI Standards for Fixed Guards
Fixed Guarding OverviewWith the release of ANSI 11.19 (2010) - Performance Criteria for Safeguarding, it consolidated all of the design, installation, operation and maintenance of Fixed Guards into a single American National Standards Institude (ANSI) standard.
In the 2010 release of ANSI 11.19 there were two fundamental changes:
This significantly simplied the process of determining whether a guard met the current ANSI standads, as there is now a single unified standard for all safeguarding.
ANSI B11.19 (2010) now applies to ALL machines and equipment. There is no longer any difference between the guarding standards for: Point of Operation Mechanical Transmission Apparatus
