TDI is the short form for the toluene Di isocyanate. Loading, carrying, and discharging this cargo is not a child’s play. And there is a reason that I say this.
TDI reacts with moisture and water. It comes under cyanide group of cargoes and is highly toxic. It can ingest through the skin. And not the physical contact but even its vapors can ingest through the skin.
And after all these, TDI may require heating as its melting point is high. So many dangerous elements in one cargo and that’s why it is important to handle it carefully.
But in spite of being so dangerous, there are hardly any cargo-specific guidelines for carrying this cargo on ships. There are some extensive guidelines for handling TDI ashore but not for carrying onboard ships.
So I am hoping this guide can fill that gap. Let’s begin our voyage to carry TDI on board a chemical tanker. Let’s embark on a journey from loading and discharging a cargo of TDI.
Receiving Voyage orders
On receiving voyage orders to carry TDI onboard, the first thing to check is if we can carry this. By that I mean if the ship is designed to carry this cargo.
