I retired from the largest children's hospital.in Pa. Many years ago somebody installed these dangerous plastic receptacle inserts. One of our sharp eyed sparkies did some investigating on them. They appeared to never have UL or other approved testing agency marking on packaging or products and could be a choking hazard to young children. Would only used hospital grade temper resistant receptacles. Besides wonder how many times a flimsy plastic receptacle insert was removed for a short period they were never replaced. You might want to double check me with JACO or forget the state of Pa agency that deals with hospitals & medical facilities. Before TR receptacle were required there were 5,000 children taken to ER'S every year for receiving severe shock & or burns from inserting something into a receptacle.
