A man who received burns to more than 70 per cent of his body following a fire near Marulan has died from his injuries.
Emergency services were called to the property on South Marulan Road believed to be operated by Foti Fireworks at about 2.40pm on Monday, where they found a box-style pantec truck and a grassed area on fire.
The blaze was extinguished and a 38-year-old was treated for severe burns at the scene, before being airlifted to Sydney's Royal North Shore Hospital in a serious condition.
He died on Tuesday morning.
A report will be prepared for the Coroner, and NSW Police and Workcover will be investigating the incident to determine how the explosion occurred.
Comment has been sought from Foti Fireworks.
