What facilities must employers provide for employees in relation to water?

Employers are required to provide employees with access to potable water, which is safe for drinking and meets health standards. This is essential for maintaining hydration and preventing heat-related illnesses, especially in environments where employees are exposed to high temperatures or engage in strenuous activities. In addition to having potable water available, employers must also provide eyewash stations in areas where employees may be exposed to hazardous substances that could harm their eyes. Eyewash stations are crucial for immediate decontamination in the event of an eye injury and are a part of the safety measures that help ensure a safe workplace.

The combination of potable water and eyewash stations reflects OSHA's commitment to maintaining health and safety standards in the workplace, making option A the correct choice for this question.
