Storage
Due to its high chloride ion concentration, the product is preferable stored in tanks made of PE or PP, or in tanks protected with a coating that is resistant to chlorides. When handling this solution it is advisable to wear protective clothing, suitable gloves and protective goggles. Contact with eyes and skin should be avoided. Avoid any possibility of TMA.HCl being neutralized with a base in the open air, as this would release trimethylamine, which is not only foul smelling but also harmful and extremely flammable (consult the MSDS for this substance).
