Clinical reports on unintentional mass exposure to extreme concentrations of @entity544 are rare. We describe an industrial incident caused by a container of liquid @entity544 that was unintentionally opened in an enclosed working environment. Twenty-five casualties reached our emergency department. Symptoms included @entity1353 , cough, dizziness, @entity662 , and @entity10 . ECGs (n=15) revealed ST-segment changes in 2 (13.3%) @entity1 , @entity955 in 2 @entity1 , and non-Q wave @entity583 in 1 @entity1 . Chest radiographs (n=22) revealed @entity3067 , consistent with @entity55 , in 6 (27%) @entity1 and @entity3126 in 2 (9%) @entity1 . Eleven (44%) @entity1 were admitted to the hospital: 8 were discharged 24 hours later and the others within 8 days. No @entity1 died. Exposure to high concentrations of @entity544 resulted in significant but transient cardiopulmonary morbidity with no mortality when victims were promptly evacuated and given supportive therapy. @entity299 were frequently observed and should be actively sought.
