Final answer:
In the context of workplace safety, the employer is responsible for labeling and marking hazardous materials, ensuring compliance with regulations, and training employees on interpreting these labels.
Step-by-step explanation:
The responsibility for workplace labeling and marking primarily lies with the employer. It is their duty to ensure that hazardous chemicals and other materials are properly labeled in the workplace with the necessary information to safely handle and store them, in accordance with regulations like the Hazard Communication Standard (HCS) enforced by the Occupational Safety and Health Administration (OSHA).
An employer must provide training to employees on how to read and understand these labels, and they should maintain labeling systems to keep all employees informed about the potential hazards. While employees are also responsible for following these labeling guidelines and using them to work safely, it is the employer who must ensure that these systems are in place and up to date.
