Final answer:
The Material Safety Data Sheet (MSDS) is the document that contains first aid and safety information for hazardous chemical spills in the workplace.
Step-by-step explanation:
The document required for information on first aid procedures when a hazardous chemical spills on an employee is D. Material Safety Data Sheet (MSDS). This vital document contains detailed information about the chemical's properties, health effects, hazards, protective measures, and safety precautions, including first aid treatment. It's imperative for workplaces to have an up-to-date MSDS for each chemical, and employees should be trained on how to access and understand this information. Additionally, safety practices, such as knowing where specific safety equipment is located—like eyewash stations—are crucial for immediate response to any accident or spill.
