A man in his 40s was hurt in Harwood Road, Littlehampton when a bonfire got out of control on Friday night.
On Saturday, a boy aged 15 burnt his face, arms and stomach when a garden fire exploded in Tennyson Road, Bognor.
And a 39-year-old man had burns to his hands and neck when his clothing caught fire in Poling Street, Poling.
West Sussex Fire and Rescue Service said the man had lit the bonfire with petrol.
Ambulances were called to all three incidents, with the two burns victims being taken to hospital.
A fire service spokesman said petrol should never be used to light or "refresh" bonfires or barbecues as the vapour could ignite.
He said anyone building a bonfire should make sure it was away from fences, garden sheds and homes and keep a bucket of water or garden hose at hand.
