What should sanitation workers use to evaluate if containers exceed the weight limit?

Using weight scales is the proper method for sanitation workers to evaluate whether containers exceed the weight limit. This approach ensures accuracy and complies with safety regulations. Weight scales provide a precise measurement of the container's weight, which is essential for preventing injury during lifting and transporting heavy loads.

Personal judgment is subjective and can lead to errors, resulting in either overloaded containers, which can be hazardous, or underestimating the weight, which could impact operational efficiency. On the other hand, visual estimation lacks the precision needed to evaluate weight correctly, and relying on passenger assistance does not pertain to assessing container weight but rather suggests an impractical approach to handling sanitation duties. Thus, using weight scales is the most reliable and safe method for checking if the weight limits are being exceeded.
