crash cool the reaction mixture if it moves outside set limits; add a reaction inhibitor to kill the reaction and prevent runaway; or dump the reaction into a quenching fluid. Selecting the basis of safety The basis of safety for a chemical reaction is the combination of Chemical reaction hazards and the risk of thermal An exothermic reaction can lead to thermal runaway, which begins when the heat produced by the reaction exceeds the heat removed. The surplus heat raises the temperature of the reaction mass, which causes the rate of reaction to increase. This in turn accelerates the rate of heat production.
