Three Sealord workers hospitalised after inhaling chlorine gas at the company's Nelson port site have been discharged, and a fourth will be released shortly.
A chemical reaction on board the berthed fishing boat Aukaha had caused a buildup of chlorine gas in the ship's hold this morning, Sealord general manager Doug Paulin said.
Four workers who inhaled the gas were taken to hospital and put on nebulisers to help their respiratory systems.They were expected to have no lasting ill-effects from the incident, he said.
The rest of the boat was cleared as a precaution, and Sealord was investigating the cause of the chemical reaction.
"It looks like it may well have been two chemicals used on two different days that have managed to come in contact with each other, so we're just working through how that would have happened," Paulin said.
