WorkSafe said a health and safety concern had been raised about a chemical spill in Whanganui.
“We are making initial inquiries to understand the circumstances but, at this stage, it is not an investigation.”
At the time of the incident, Fire and Emergency New Zealand Manawatū-Whanganui assistant commander Craig Gold said the chemical had been on-site for a number of years and people were trying to get rid of the substance when it had been spilled.
The chemical – perchloroethylene – is widely used for dry cleaning fabrics to dissolve grease stains.
It was not harmful in small amounts but a concentrated amount that had evaporated into a gas could be dangerous, Gold said.
Hato Hone St John said two patients, one in a serious condition and one in a moderate condition, were taken to Whanganui Hospital.
Firefighters successfully contained the spill and the business is open to the public.
