1) Exposure to oil-based drilling fluids can cause skin disorders like dermatitis through skin contact during activities like cleaning, handling, pumping, mixing, or from spills.
2) Barrier creams can provide secondary protection if skin contacts fluids, but should not be relied on to prevent dermatitis or absorption as they are not fully protective. Water-based creams are recommended to be used with oil-based fluids.
3) A good skin lotion applied after work can help regenerate the skin's natural defenses and replace oils lost from contact with oil-based drilling fluids.
