What PPE item is appropriate to protect against dermal absorption of toxicants?

To protect against dermal absorption of toxicants, the most appropriate choice is a chemical resistant suit. This type of personal protective equipment (PPE) is specifically designed to prevent hazardous substances from coming into contact with the skin. Toxicants can enter the body through the skin, therefore, a chemical resistant suit provides full body protection, covering all exposed skin and preventing any potential absorption of harmful substances.

While sturdy rubber gloves and rubber boots do provide barriers to some extent, they only protect the hands and feet respectively and do not cover the entire body. A respirator is designed to protect the respiratory system from inhalation hazards but does not address skin exposure at all. In comparison, the chemical resistant suit is the most comprehensive option for skin protection against a wide range of chemical hazards.
