Your containership has a container displaying a hazardous cargo placard. The placard has the number 2206 on it. This indicates that it is carrying what cargo?

Correct Answer: Option B — Isocyanates, n.o.s.

UN Number 2206 designates isocyanates or isocyanate solutions, toxic by inhalation and skin absorption. Under 49 CFR and IMDG dangerous goods lists, marine officers must verify proper hazard communication placards for Class 6.1 toxic substances to ensure safe stowage and segregation.
