A CHIP pan blaze broke out at a flat in Runcorn in the early hours of this morning.
Two male casualties were given oxygen by firefighters after a cooker filled a ground floor flat with smoke.
A crew from Runcorn and one from Widnes tackled the fire in Lockfield, Weston Point at 1.31am.
A spokesman for Cheshire Fire and Rescue Service said:”Smoke was caused by an unattended pan on a cooker.”
Firefighters wearing breathing apparatus extinguished the flames.
Crews used a high pressure fan to clear the smoke.
A spokesman for North West Ambulance Service NHS Trust said: “An ambulance was called at 1.44 but we didn’t take anyone to hospital.”
