Reactive chemical hazards

Reaction Hazards and Thermal Runaway

Exothermic chemical reactions are performed the world over by companies as part of the normal manufacture of their products and intermediates. These reactions carry with them an inherent risk of loss of control, with potentially devastating effects on life and the environment.

How Chilworth Can Help:
