He noted that as more industries became aware of the health problems associated with methylene chloride they were slowly reverting to the use of CFCs for foam-blowing The safe use of methylene chloride might not be a viable solution as the cost of putting the necessary safety mechanisms in place could be prohibitive.
L'utilisation sans danger du chlorure de méthylène pourrait ne pas constituer une solution viable, étant donné que le coût de la mise en place des dispositifs de sécurité nécessaires risquait de s'avérer prohibitif.
