A construction worker who left a flaming blow torch on top of a gas bottle while he had a cigarette is being investigated.
The man is a contractor working on The Crossing at Highbrook Business Park in East Tamaki and a passer-by spotted him in the act, took a photograph and sent it to the Herald.
A spokeswoman for Highbrook Development, which owns Highbrook Business Park, said they took health and safety seriously and were concerned at the actions highlighted by the photo. She said they were investigating the matter with its contractor as a matter of urgency.
Officials will also follow up with the construction site.
The Ministry of Business, Innovation and Employment's chief health and safety inspector, Keith Stewart, said a naked flame resting on top of a gas cylinder was an unsafe practice.
