Transportation of Toluene diisocyanate – The real challenge
TDI abbreviated as Toluene diisocyanate (C9H6N2O2) is the key ingredient in the manufacture of polyurethane (PU) foam. About 90% production of TDI is consumed for the making of mattresses, car seats and furniture foam; in addition to these they are also used in adhesives, paints and concrete sealers. It is a known fact that Toluene diisocyanate is toxic and carcinogenic, in-spite of this its usage has not declined as their uses are such, & there are no replacements.
Transportation of TDI is very challenging and has to be carried out with in-depth knowledge and care. Lets jot down the basic points to be kept in mind on the nature of Toluene diisocyanate to achieve safe transportation.
- It is a Highly Toxic Chemical.
- Vigorously reacts with water.
- It is heat sensitive.
- Decomposes to emit Poisonous fumes.
- TDI violently reacts with polyols.
- It also reacts with Acids, Peroxides & Alkalies
Important point to be strictly followed while transporting TDI barrels are :-
- A dedicated vehicle should be assigned for transportation of TDI & there should be no clubbing of other chemicals or products.
- Closed body vehicles are highly recommended.
- Barrels should not be loaded in horizontal position.
- Drivers should be educated on the nature of TDI and TREM (Transport Emergency) card be issued.
- Leaks should be attended wearing appropriate personal protective equipment.
- In case of TDI leak, change the position of the barrel so as to stop the oozing and then take necessary steps to arrest leakage.
Major considerations for the transport of TDI have been discussed. Needless to say educating the workers on safe handling of TDI is the key to avoid mishaps.
