How should sanitation workers determine if a container is too heavy?

The correct approach to determining if a container is too heavy is to weigh the container on a scale. This method provides an objective measurement of the container's weight, ensuring that sanitation workers can accurately assess whether it exceeds the safe lifting limit. Lifting a container to test its weight can lead to potential injury if the weight is indeed too heavy, and relying on guesswork or subjective judgment may not provide a reliable assessment, especially in environments where safety standards are crucial. Similarly, asking a coworker for their opinion does not provide the precision needed to make safe decisions regarding lifting. Ultimately, using a scale represents the safest and most accurate method for sanitation workers to ascertain if a container is excessively heavy.
