Children's Halloween costumes can "quickly go up in flames" even if touched briefly by a naked flame, a fire service has warned.
Devon & Somerset Fire and Rescue Service say the costumes should be "treated as high risk" because their designs, often featuring capes and petticoats, mean they can easily catch fire and "engulf a child in flames."
They are advising adults to only buy Halloween costumes from reputable retailers and always check the label.
Clothing will always burn if exposed to a naked flame, but some materials catch fire much faster than others.
People do not realise just how quickly a costume can catch fire and the fire spread. The design of costumes, with flowing robes, capes or petticoats means they could easily catch fire from a candle or flame and swiftly engulf a child in flames.
Here are some of Devon & Somerset Fire's safety tips:
Avoid using a candle in pumpkins - use a torch, glow-stick or battery operated candle.
If a costume does catch fire, use the 'Stop, Drop and Roll' technique to try and extinguish the flames.
Choose a costume and mask that doesn't restrict a child's visibility.
Wear clothing underneath the costume - preferably a woollen jumper, woollen tights or jeans.
Avoid capes, trains and dangling sleeves.
They are urging parents to buy costumes that meet European Toy and British nightwear flammability safety standards.
If making a costume at home, they advise:
Use polyester, nylon, wool and acrylic fabrics.
Make sure the costumes are not loose-fitting.
Avoid materials using natural fibres, like cotton wool balls.
Don't use bin liners as capes or dresses.
