Type 2 vs Type 4 Safety Light Curtain

Type 2 vs Type 4 Safety Light Curtain — Decision Tool

1. What is the most severe injury that could result from the hazard?

2. How frequently are operators exposed to this hazard?

3. Can the operator avoid the hazard after detection?

4. What does your site risk assessment specify?
