2,4-Dichlorophenol (2,4-DCP) is a feedstock chemical primarily used to produce the herbicide 2,4-dichloropheoxyacetic acid (2,4-D). In October 1998, the U.S. Environmental Protection Agency (EPA) was notified of the death of a worker acutely exposed to 2,4-DCP. Follow-up investigation by EPA, the Occupational Safety and Health Administration (OSHA), and CDC's National Institute for Occupational Safety and Health (NIOSH) identified four earlier deaths associated with acute 2,4-DCP exposure, which occurred during 1980-1992. All of these incidents resulted in rapid death after dermal exposure to the heated liquid form of the chemical. This report describes the five deaths associated with 2,4-DCP exposure (presented in the order in which they were identified) and provides recommendations for preventing additional deaths.
Isolated impalement injury to the urinary bladder is a rare occurrence. We present a case in which the delay in the diagnosis reveals the potential pitfalls in the management of such injuries.
We report here 9 patients suffering from hydrofluoric acid burn who visited our clinic from July, 1979 to February, 2000. These 9 cases occupied 25% of all chemical burn cases experienced in our clinic. All the patients were men ranging in age from 20 to 53 (mean age 35 years; average 36.8 years). At the time of accidental exposures, 6 patients had been engaged in washing or cleaning work, and 2 had been changing the parts of instruments containing hydrofluoric acid. Eight patients received burns on the hands and/or fingers. During the work, 2 patients had used vinyl chloride or rubber gloves, but three patients employed no protection for the hands. After the symptoms began to develop, it was found that the glove of one patient had a pin hole. Coupled with the occasions described in previous reports, the causal factors of hydrofluoric acid burn could be divided as follows: 1) negligence or carelessness of workers, in particular skilled persons, in handling hydrofluoric acid, 2) ignorance of the dangerousness of hydrofluoric acid, 3) the presence of pin hole (s) in protection gloves, and 4) unexpected accident. Hydrofluoric acid is one of the most corrosive inorganic acids, and can produce progressive and serious tissue necrosis with severe pain. To prevent burns due to this chemical, enlightenment and reeducation of the workers regarding the hazard of hydrofluoric acid are necessary.
