Lifting Standards
Defining & Agreeing Best Practice:
• Design• Testing• Application
• Developing Standards for Safety barriers
![Page 41: Lifting Standards in Warehouse Barrier Protection · Energy Calculation Angles of Impact ... • Don’t fix Barrier too Close to Walkway ... •Over head crossing points](https://reader031.vdocuments.us/reader031/viewer/2022021802/5b655d697f8b9a6e1f8ba12c/html5/thumbnails/41.jpg)
• Safety Can be “Designed in”• Risks Reduced or
Eliminated Completely
Designing in Control
