Historically, the factory deplores two severe accidents with sulphuric acid 98% splash and caustic soda 30% splash which resulted into long lost work times and for one case it resulted into surgical intervention. These facts lead the "safety persons" to change their emergency protocole. Since then, they are using Diphoterine®, and the factory only registered accidents without sequelae and lost work time. The users of Diphoterine® are deeply convinced of its efficiency.
