Final answer:
Safety Data Sheets are the main source for first aid information on hazardous materials at a workplace, offering thorough guidance on handling, potential risks, and emergency measures.
Step-by-step explanation:
The correct answer is option A. Safety Data Sheets (SDS) are the primary source of first aid information about hazardous materials for employees at a work site. These sheets provide critical information on how to handle chemicals safely and emphasize the precautions and actions to be taken in case of an emergency. This includes first aid measures, potential health effects, chemical properties, storage, disposal, protective equipment, and spill-handling procedures.
Employers are required to ensure that SDS are readily accessible to all employees for all hazardous chemicals in their workplace, as mandated by the Occupational Safety and Health Administration (OSHA). The OSHA List of Highly Hazardous Chemicals is an additional resource providing information on chemicals considered as highly hazardous and their associated risks.
