NSW Fire will remove specialised fire trucks designed to combat high-rise fires and perform apartment building rescues from Sydney's north-west and south-west because of budget cuts.

The Sun-Herald has learnt that the "Brontos", capable of reaching 37 metres, will be removed from fire stations at Hornsby and St Andrews, near Liverpool, and mothballed to save money on staffing them with specialised crew.

NSW Labor's emergency services spokesman Guy Zangari has lashed the decision, which he says "doesn't make sense" when metropolitan Sydney was being transformed by high-rise apartment construction, particularly around railway stations.

"The government will save dollars but is that at the expense of community safety? There is the classic story of the fire in Bankstown – that could happen anywhere in Sydney. If the Bronto is not within distance it will put someone's life at risk," said Mr Zangari.
