What must sanitation workers do upon encountering a hazardous waste container with unknown contents?

Sanitation workers must prioritize safety and adhere to established protocols when encountering a hazardous waste container with unknown contents. Reporting it to a supervisor is the appropriate action because supervisors are trained and equipped to handle such situations safely. This procedure ensures that trained professionals can assess the potential risks and determine the best course of action, which may include further investigation by specialists or the appropriate cleanup measures.

Directly checking the contents themselves could expose the sanitation worker to harmful substances, leading to potential health risks. Ignoring the container jeopardizes the safety of other workers and the environment, while disposing of it with regular waste could violate legal and safety regulations, leading to severe consequences. By reporting the situation, workers contribute to a safer workplace and ensure compliance with regulations surrounding hazardous materials.
