How can a worker ensure effective use of a step ladder?

To ensure effective use of a step ladder, it is essential to spread the legs properly and avoid stepping on the top. Properly spreading the legs provides stability, reducing the risk of the ladder tipping over during use. A stable base is crucial for maintaining balance and safety while reaching for an object at a height.

Additionally, the top step of a ladder is typically not designed for standing, as it does not provide the same level of support or security as the lower steps. Using the top step can lead to loss of balance and increases the likelihood of falls.

In contrast, using a ladder on uneven ground can cause instability, and keeping it fully extended may not be necessary for all tasks, especially if it compromises safety. Placing the ladder near hazardous materials can also create dangerous situations, as it can lead to potential exposure to harmful substances or accidents. Hence, following proper ladder usage protocols is crucial for worker safety.
