What must employees do if they suspect the presence of hazardous materials?

When employees suspect the presence of hazardous materials, the appropriate action is to notify a supervisor. This is crucial because supervisors are typically trained to handle situations involving potential hazards and can take the necessary steps to ensure the safety of all employees. They are in a position to assess the situation correctly, initiate emergency protocols if needed, and inform relevant safety personnel who may need to intervene or conduct further evaluations.

Notifying a supervisor ensures that the situation is handled by someone with authority and knowledge regarding safety regulations and procedures. This chain of communication is vital in maintaining a safe working environment and ensuring that proper procedures are followed for handling hazardous materials, which can have significant health implications if not addressed appropriately.
