Is De Quervain's disease an OSHA recordable?

It depends. 29 CFR 1904.5(a) states, “You must consider an injury or illness to be work-related if an event or exposure in the work environment either caused or contributed to the resulting condition or significantly aggravated a pre-existing injury or illness. Work-relatedness is presumed for injuries and illnesses resulting from events or exposures occurring in the work environment unless an exception in §1904.5(b)(2) specifically applies.”
