Abstract: On October 24 and 25, 1992, employees from California Conservation Corps (CCC), under contract with MSE Environmental, Inc., participated in a household hazardous waste day project at the Earl Warren Showgrounds in Santa Barbara, CA. Employee #1 suffered chemical burns to his feet. Several other employees suffered symptoms associated with overexposure including headache, dizziness, vomiting, and intoxication. Initially, according to a CCC employee, MSE had requested trained employees. Employees having 40 hours of hazardous waste training were scheduled. However, at a later time, MSE apparently requested different employees. Under the terms of the contract, MSE was to provide CCC employees the necessary personal protective equipment not already provided by CCC. In addition, a safety meeting was to be conducted prior to work.
