Take-Home Toxins' Expand Duty of Care

American Bar Association Section of Litigation, Environmental & Energy Litigation Committee’s Spring 2017 Newsletter

The article discusses the recent Schwartz v. Accuratus Corp. decision issued by the U.S. District Court in Pennsylvania. The court held that a ceramics manufacturer, Accuratus Corporation, could be liable under New Jersey law for chemical exposure injuries to a woman who was both the girlfriend of one of its employees and the roommate of another employee. The woman allegedly suffers from chronic beryllium disease, which she believes was caused by exposure to beryllium brought to her home on her boyfriend and roommate’s clothing and shoes. According to the article, the case represents an expansion of an employer’s duty for secondhand exposure beyond a traditionally defined household, effectively opening the door to a new class of plaintiffs.
