When using ladders in the workplace, it is important to follow specific safety guidelines to prevent accidents and injuries. Here are some key safety requirements and best practices based on the provided documents:

1. Securing Ladders: Ensure that portable ladders are secured against accidental movement during use. This can be achieved by using non-slip feet or securing the ladder to a stable structure [1].

2. Extension and Positioning: A portable ladder should extend at least 1 meter above any platform, roof, or other landing to which it provides access. The ladder should be placed at a slope of 1 horizontal to 4 vertical [1].

3. Material and Condition: Ladders should be clean and free of substances like grease or oil that may cause slipping. They should also be inspected before each use and annually by a competent person to ensure they are in safe condition [2].

4. Usage Restrictions: Workers should not work from the top two rungs of a portable ladder unless it is a stepladder with a platform and suitable handrail. Additionally, workers should maintain a three-point stance on the ladder at all times [1].

5. Load Capacity: Ladders should not be loaded beyond their maximum intended load, which includes the weight of the worker and any tools or materials being carried [3].

6. Electrical Safety: Metal or wire-bound ladders should not be used where they may come into contact with exposed energized electrical conductors [1].

7. Training: Employers should ensure that workers are instructed in the safe handling and use of ladders, including understanding the requirements and restrictions outlined in safety regulations [1].

By adhering to these guidelines, you can help ensure a safer working environment when using ladders.
