What must employers provide as part of the HazCom Standard?

The correct choice is that employers must provide labels and safety data sheets (SDS) as part of the Hazard Communication (HazCom) Standard. This requirement is fundamental to ensuring that all employees are informed about the hazardous chemicals they may encounter in the workplace.

Labels serve as a crucial first line of defense by providing immediate visual identification of potential hazards associated with the chemicals, including signal words, hazard statements, pictograms, and precautionary statements. Meanwhile, safety data sheets contain detailed information about the chemical, including its properties, protective measures, and safety precautions for handling, storing, and responding to emergencies.

The combination of labels and SDS ensures that workers have access to comprehensive information, allowing them to understand the hazards, take appropriate safety measures, and respond to incidents effectively, thereby promoting safety in the workplace.

While the other options touch on aspects related to hazard communication, they do not encompass the full regulatory requirement that employers must fulfill under the HazCom Standard. The obligation to communicate hazards through written plans, verbal communication, or selective training does not replace the fundamental necessity for comprehensive labeling and availability of SDS for all hazardous chemicals present.
