Fixed Guarding Overview

With 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:

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

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.

Performance Requirements

Within the ANSI B11.19 (2010) Performance Criteria for Safeguarding, there are a number of important requirements. These include:

7.1.1 Material used in the construction of guards shall be of such design and strength as to protect individuals from identified hazards.

7.1.4 The design and construction of the guard shall ensure that individuals cannot reach the hazard by reaching over, under, around, or through the guard.

7.2.1 Location of the guard with respect to the hazard shall ensure that individuals cannot reach the hazard by reaching over, under, around, or through the guard.

7.1.5 Guards shall be designed and constructed so as to ensure ease of use.

7.1.6 The guard shall be designed and constructed to provide visibility of the hazard zone appropriate to the particular operation.
