Importance of B11 Standards

Participation in B11 Standards aids organizations in achieving acceptable risk and facilitating feasible risk mitigation.
Provides companies an opportunity to influence future standards and reflect their industry voice.
Engages participants in a deeper understanding of evolving safety regulations.
Offers excellent networking possibilities with safety specialists across diverse sectors.
Encourages cross-educational opportunities among various stakeholders.

B11.19 Overview

This standard outlines performance requirements focusing on design, construction, installation, operation, and maintenance of risk reduction measures for machines.
Sections detail inherently safe designs, engineering controls (guards, control functions, devices), and administrative controls.

B11.19 Historical Context

Initiated in 1980 to collate information on safeguarding; the first edition approved in 1990.
The second edition, approved in 2003, updated safety data and distance requirements.
The third edition in 2010 redefined requirements including Protective Stops and Emergency Stops.
The latest edition in 2019 reorganized content following the hierarchy of controls, encompassing significant updates from the 2010 version.

Safety Distance Considerations

Engineering controls must be located at a safe distance from hazards to prevent exposure.
Correct safety distance calculations are vital for effective guard functionality and safe states.
Procedures for determining safety distances must be documented and are based on risk assessments.

Interlocking Systems Comparison

Trapped Key Interlocking systems offer easy installation but can be complex without programming.
Interlocks should be maintained for optimal operation and cannot be physically locked with a padlock.
Non-contact interlocks can be either coded or uncoded, expanding safety options.

Movable Barrier Devices

Movable Barrier Type A holds the hazard zone closed until the machine stops fully, thus ensuring safety during operation.
Movable Barrier Type B remains closed throughout hazardous machine cycles, safeguarding against access during risk phases.
