In its role as a primary defender against external insult, the skin is particularly vulnerable to damage by physical and chemical assaults in the workplace. Barrier function represents only a fraction of the duties performed by the entire integumentary system, which participates directly in thermal, electrolyte, hormone, and immune regulation without which life is not possible. The metabolic potential of the skin is impressive, and rather than merely repelling chemical or physical assaults, the skin may compensate by metabolizing and biotransforming agents to less harmful ones. Hence, the skin is far from a passive coat of armor but rather an interactive organ that is in constant flux with its environment.

The skin's precarious location has rendered it the most commonly injured organ from chemical agents and physical conditions of the workplace. Pathologic responses of the skin can vary from excessive dryness and mild redness to more generalized exfoliative dermatitides that are life threatening.
