When handling mercury, it is essential to wear PPE that provides adequate protection against its hazardous properties. Mercury is a toxic metal that can pose serious health risks through skin contact and inhalation of vapors. Therefore, the most effective PPE should include materials that are resistant to mercury and help minimize exposure.

Using a neoprene splash suit, apron, or coveralls offers a significant defense against spills and splashes, as neoprene is resistant to many chemicals, including mercury. Neoprene gloves are also crucial because they prevent direct skin contact, which could lead to mercury absorption. Rubber boots provide additional protection for the feet and minimize the risk of contamination through footwear. Splash-proof chemical goggles are necessary to protect the eyes from potential splashes or vapors, which is vital since mercury vapors can be harmful when inhaled or when they come into contact with skin or mucous membranes.

This combination of PPE ensures comprehensive protection and adheres to safety protocols when working with hazardous materials like mercury. Thus, the choice of neoprene and rubber materials along with protective goggles reflects a proper understanding of the risks involved in handling mercury, making this the correct answer.
