When working from elevations, it is crucial to follow specific safety protocols to prevent falls and ensure worker safety. Here are some key safety requirements and practices based on the provided documents:

1. Fall Protection Systems: Employees working on surfaces 6 feet (1.8 meters) or more above lower levels must be protected by guardrail systems, safety net systems, or personal fall arrest systems [1]. This is essential to prevent falls from heights.

2. Work Positioning Systems: If a worker uses a work positioning system, the vertical free-fall distance should be restricted to 600 millimeters or less. Additionally, if the worker's center of gravity extends beyond an edge, a back-up personal fall arrest system must be used [2].

3. Control Zones: When using control zones, ensure they are at least 2 meters wide from the unguarded edge and clearly marked. Workers within 2 meters of the control zone should use appropriate fall protection systems [2].

4. Ladders and Access: For moving between levels more than 450 millimeters apart, a fixed ladder, stairway, or ramp should be installed [3]. Portable ladders should be inspected before use, and workers should maintain their center of gravity between the ladder's side rails [4].

5. Scaffold Safety: Ensure scaffolds are equipped with guardrails and are inspected regularly. Workers on scaffolds should use personal fall arrest systems if they are 3 meters or more above the ground [5].

6. Training and Competency: Workers performing tasks at heights should be competent and trained in the use of fall protection systems and the specific procedures for their tasks [2].

By adhering to these guidelines, you can significantly reduce the risk of falls and ensure a safer working environment when working from elevations.
