When working from elevations, it is crucial to implement effective fall protection measures to ensure worker safety. Here are some key safety requirements and practical advice based on the provided documents:

1. Fall Protection Systems: Ensure that employees working on surfaces 6 feet (1.8 meters) or more above lower levels are protected by guardrail systems, safety net systems, or personal fall arrest systems [1]. This is essential to prevent falls from unprotected sides and edges.

2. Work Positioning Systems: If using a work positioning system, restrict the worker's vertical free-fall distance to 600 millimeters or less. Additionally, use a back-up personal fall arrest system if the worker's center of gravity extends beyond an edge or if the work surface presents a slipping or tripping hazard [2].

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

4. Ladders and Access: Install fixed ladders, stairways, or ramps when employees need to move between levels that are more than 450 millimeters apart [3]. Ensure ladders are inspected before use and secured against movement [4].

5. Scaffold Safety: Ensure scaffolds are equipped with guardrails and are not moved with unsecured tools or materials on them. Regular inspections by competent persons are necessary to maintain scaffold safety [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.
