Hierarchy of Fall Protection
1
Elimination

Work from ground level using extended tools

2
Passive Protection

Guardrails, safety nets, hole covers

3
Work Positioning

Restraint systems that prevent falls

4
Fall Arrest

Systems that stop a fall in progress

5
Administrative Controls

Training, procedures, supervision
