Six String Brewing Company at Erina was forced to close after a gas explosion on Monday, October 28.
The incident occurred just before midday in the kitchen, causing severe facial burns on a kitchen hand aged in her 20s.
NSW Fire and Rescue responded at about 11.45am and NSW Ambulance paramedics treated the woman before she was transferred to a CareFlight helicopter which took her to Royal North Shore Hospital in a serious condition.
Authorities have ruled out any suspicion around the incident, attributing the explosion to a sudden ignition of gas on the cooktop.
Six String Brewing addressed the incident on its Facebook page, notifying customers that the taproom would remain closed until further notice.
“Thanks to the quick response of our team on-site, emergency services were immediately contacted and CareFlight was able to transport her swiftly to receive urgent medical care,” the Facebook statement said.
“We are unclear on the severity of the burn but our thoughts are with her (the staff member) and we are hoping to get an update as she is assessed by medical professionals.
“Fire and Rescue are onsite to investigate the cause of the accident and are reinforcing all safety measures to ensure the safety of everyone onsite
“Our priority is our staff first and foremost.
“As we are receiving updates on our injured staff member, we also want to make sure the rest of our Six String family is 100 per cent before opening our doors.
“Our kitchen is currently undergoing repairs and checks to ensure we are running smoothly for re-open.”
A police investigation is underway.
