Four people are being treated for exposure to ammonia following an incident near Palmerston North this afternoon.
St John said it received a call about an incident on Works Rd, Longburn around 3.38pm.
“Four people have been taken to Palmerston North Hospital in a moderate condition.”
It responded with one ambulance, one rapid response unit and an operations manager, a spokesperson said.
Fire and Emergency NZ said it was called to assist ambulance services after people were exposed to ammonia.
The leak has been isolated and there is no concern for public safety, a spokesperson said.
Ammonia exposure can cause symptoms such as difficulty breathing, irritation of the eyes, nose, or throat, and burns and blisters.
Low-level exposure through inhalation can cause coughing and breathing difficulties and high-level exposure through inhalation can cause lung damage, leading to death.
Worksafe said it has been notified and is making initial inquiries.
