Employers today must be presumed to know of the dangerous nature of many chemicals which produce contact dermatitis, as well as respiratory and other injuries. Among the known-to-be-dangerous substances are such things as chrome compounds, lead compounds, petroleum compounds, and many others. The danger of sensitization by these substances also must be presumed to be known. It follows that an employer is legally bound to take all reasonable possible precautions to protect his workers from such injuries. Whether or not he has taken adequate precautions is a question of fact, for the jury. If he has taken no special precautions, he may be guilty of negligence as a matter of law.
