When calculating the total weight a ladder is to support, what must be included?

The correct answer encompasses the necessity of considering all potential factors that contribute to the total weight a ladder must support. When calculating this weight, it is essential to include the weight of the user, any tools they are carrying, and even the weight of their clothing. Each of these elements can significantly impact the overall load on the ladder.

The user's weight is vital since it forms the primary load the ladder must support. Additionally, the weight of tools is crucial because workers often carry various equipment that can add considerable weight. Lastly, clothing, although it may seem negligible, can add to the total load. All these components together help ensure that the ladder is being used safely within its design limits, thereby preventing accidents due to overloading. Proper risk assessment is fundamental for safe ladder use, and accurately calculating the total weight helps in adhering to those safety guidelines.
