Following the hearing at Nottingham Coroner's Court, the fire service highlighted the dangers of using portable cooking devices in enclosed spaces.
Richard Leighton, head of community safety and engagement, said: "These devices should only be used in well-ventilated, appropriate outdoor areas.
"It is essential to check that equipment is in good condition before use, to never leave it unattended while operating, and to ensure it is cleaned and safely shut down afterwards."
