Fire destroyed a mobile home on an estate near Burgess Hill.
The blaze was extinguished within hours but police closed off a mile-long section of road while they dealt with heated gas cylinders, which could have exploded.
Neighbours dialled 999 when they saw smoke coming from the mobile home at Leigh Mill in Cuckfield Road, Goddards' Green at about midnight on Sunday.
Fire crews worked through the night to extinguish the flames. The building was completely destroyed. No one was hurt. The section of road from Ansty to the Goddards' Green roundabout was expected to remain closed for most of Monday while fire crews cooled acetylene cylinders used for heating and cooking.
Investigations are being carried out to find out how the fire started.
