Comfort is the first thing most passengers think about when they get dressed for a flight, and fire safety rarely crosses anyone's mind. Noor de Swart, Founder and CEO of Super Label Store, says your choice of fabric could make the difference between walking off a plane and being stretchered off one.



Why should you avoid wearing synthetic clothing on a plane

"Most people pick their flight outfit based on comfort, and that usually means reaching for something stretchy like leggings or a polyester hoodie," de Swart says. "What they don't realize is that synthetic fabrics like polyester, nylon and acrylic can melt directly onto the skin when exposed to high temperatures. Natural fibers like cotton, wool and linen will char, but they won't melt, and that is a crucial difference."

When exposed to fire or extreme heat, a lot of synthetic fabrics will ignite and continue to burn. Some will also melt onto the body. Injuries from that kind of burn are often severe, because the molten material goes on transferring heat to the skin long after the flames have died down.


What actually happens to synthetic fabric in a fire?

The danger comes down to how the fibers behave under extreme heat. Synthetics are made from plastics, essentially, and plastics melt. A polyester shirt exposed to flames won't just burn and fall away from the skin. It liquefies, sticks, and keeps burning.

"The melting is what really scares me," de Swart says. "A cotton T-shirt might catch light, but it won't bond to your skin. A polyester blend will. Once molten synthetic gets into a burn wound the scarring is far worse, because the fabric itself becomes part of the injury."

Melting is possible even when the flames themselves last only a few seconds, which is what makes synthetic clothing so dangerous inside an aircraft cabin.

That said, the fabrics are not all equally risky. Nylon tends to melt at a lower temperature than polyester and drips as it burns, which can spread the injury further down the body, while acrylic catches quickly and goes up fast.

"The safest approach is to avoid all of them when you fly," de Swart says. "If you do wear one synthetic layer, make sure it is not sitting directly against your skin. A cotton base layer underneath makes a real difference."


Here’s what you should wear on a plane instead

De Swart recommends sticking to natural fibers wherever possible. "Cotton, wool, linen, even silk are all far safer options," she says. "A pair of cotton joggers and a merino wool sweater will keep you just as comfortable as any synthetic activewear, and they behave in a completely different way if exposed to flames."

It is always advisable to take a large scarf, cotton or silk, to cover your neck as cabin air can get quite chilly. Natural-fiber layers breathe better too, which helps regulate your body temperature during a long flight.


What if you are only flying for an hour or two?

The length of the flight makes no difference, de Swart says. "Any flight, short or long," she says. "Aircraft fires develop extremely quickly when they happen. You don't get the luxury of time to change what you're wearing. What you have on when you board is what you have on if something goes wrong, so it pays to think about it before you leave the house."
