The requirements of ANSI Z136.1 (Section 4.3.10.2) specifies that a Class 4 laser controlled area shall incorporate one of the following alternatives:
Non-Defeatable (non-override) Area or Entryway Safety Controls
Defeatable Area or Entryway Safety Controls
Procedural Area or Entryway Safety Controls
This presentation will examine all of these alternatives. Specific examples will be shown of area interlocking options including both entryway and laser barrier interlocking methods.
An area interlock interface for entryway and/or laser protective barriers will be discussed with sample circuits and function.
Procedural area or entryway safety controls will be received with a discussion of training requirements, laser protective barriers and/or protective windows and entryway warning signs and lights.
