Three adults and a child have been rushed to hospital after they were overcome by poisonous fumes from a barbecue lit inside a house.

Firefighters and other emergency services responded to a call from a home on Wentworth Street in Wentworthville at 3am on Saturday and quickly detected a carbon monoxide leak.

The four people reported feeling unwell as a result of the fumes from the barbecue.

Fire and rescue NSW Superintendent Tim Hassiotis told 7News crews that specialist firefighters detected high levels of carbon monoxide in the house using special monitoring equipment.

It's understood the gas emanated from use of a charcoal briquette BBQ inside the home.

'These types of equipment, used as heaters, pose a very dangerous threat,' said Supt Hassiotis, and warned people about the risks of using such equipment to generate heat.

'We urge those using this kind of equipment to only use them in a well ventilated area.'

The four people affected remain in a stable condition at Westmead Hospital and Westmead Children's Hospital.
