Investigations of restaurant associated occupational burns by the state health departments in Colorado and Minnesota were summarized. In Colorado from February 1989 through March 1993, 676 burns were reported that required inpatient hospital care. Of those, 29 occurred in restaurants and the patients ranged in age from 16 to 60. Of the 29 employees burned at restaurants, 17 sustained grease burns and 15 were associated with the use of deep fryers. The proportion of their body surface that was burned ranged from 1 to 30%. Total cost for the injuries for 24 of the 29 ranged from 1,690 to 100,495 dollars. Follow up workplace investigation by the Colorado Department of Health identified several specific incidents associated with use of deep fryers that increase the risk for inadvertent contact with hot grease. In Minnesota from August 15, 1990 to August 14, 1991, 71 adolescent workers incurred work related burns, of which four required hospitalization. Of these, 28 occurred in fast food restaurants and 26 in full service restaurants. Of the 28 fast food burns, 14 involved hot grease and of the 26 full service burns 11 involved hot grease. Thirty one of these 71 adolescents suffered permanent scarring.
