Abstract: Employee #1 through #6 were using freon TF in a cutting oil to degrease a system of aircraft parts. A temperature sensor in the freon separation still heating unit faulted, causing overheating. Thermal decomposition of the freon and the cutting oils in use resulted. At one point, enough heat was being generated by the freon decomposition to continue the action with no outside source of energy needed. The successive gases given-off--hydrogen sulfide, hydrochloric acid, and hydrogen fluoride--overcame Employees #1 through #6. A solution of soda ash and water was added to the reacting chemicals to neutralize the process.
