Vessel solution contains methanol, chloroform, sulfur dioxide, and iodine. Care should be taken to avoid contact with these chemicals. 3.2 Monogoggles and rubber gloves are required. Mixing the solution should be done under the hood. 3.3 The waste from the samples must be stored under the hood in a one gallon metal waste container. A thermocouple connected to an alarm must be maintained in the container. The set point of the alarm is 80C. ARC tests have shown an exothermic onset temperature of 110C. 3.4 The waste container can be dumped into the lab waste pak when full. A five day isothermal ARC test at 50C has been conducted by the reactive chemicals group. A mixture of 50% coulometric waste and 50% "normal" lab waste showed no exothermic activity. 4.0 Special Notations: 4.1 Care should be taken not to get any water in the solution. 5.0 Equipment: Date Printed: April 19, 1998 Paper Copies Of This Document Are Uncontrolled And Not Subject To Update.
