Fire crews attended three emergency call outs in Hailsham and Polegate during union strike action over the weekend.
Members of the fire brigade union at East Sussex Fire and Rescue Service staged three walkouts.
These were on Friday (May 2), Saturday (May 3) and Sunday (May 4).
It followed a dispute with the government over pensions.
The fire service said it prioritised life threatening incidents and during the strike action attended these incidents.
East Sussex Fire and Rescue Service has now resumed normal cover.
During the last day of strike action on Sunday, which took place between 10am and 3pm, crews said they attended a small number of calls.
Crews were called to Hailsham after reports of a road traffic collision.
The incident happened in Magham Down at around 3pm.
The car driver, suffering an arm injury, was taken to Conquest Hospital in Hastings by ambulance crews.
The air ambulance was also in attendance and assisted crews on the ground.
The fire brigade also attended a motorbike on fire in Eastbourne at 1.44pm.
Crews attended the incident but the fire was out on arrival.
A spokeswoman for East Sussex Fire and Rescue Service said: “Additionally there were three calls which we attended and turned out to be false alarms with good intent.
“Reports of a car fire in Polegate.
“Report of a car fire in Hove and reports of the smell of burning in Hailsham.
“Two calls did not need action - an automatic fire alarm or false alarm due to apparatus, and a controlled burn.
“East Sussex Fire and Rescue Service would like to thank members of the public for staying safe during this time.”
During the strike action contingency fire crews were on duty throughout the day and night.
Speaking on the third day of strike action, Matt Wrack, Fire Brigades Union general secretary, said: “Yet again firefighters have shown the strength of their anger over government attacks on their pensions and have been united in standing up for a fair, workable and affordable deal.
“It’s very disappointing that we’ve been forced to hold another three days of strikes but nothing will deflect firefighters’ resolve when the future of their families — and the fire and rescue service itself — is at stake.”
