Italian media reported that the solvent, which the three seafarers were using to clean the tanks on board the Russian-flagged tanker, reacted with the cargo remnants to form toxic fumes.
The deceased 24-year crew member died immediately due to a cardiac arrest, while the other two, aged 42 and 28, were transferred to a hospital in a serious condition, the media reported.
The ‘Araz River’ subsequently returned to Vasto where it had discharged a canola cargo and the vessel remained in port for an investigation to be conducted.
There were 13 Russian crew members on board at the time of the incident, the reports said.
