You love a good summer barbecue and wisely use sunscreen if you are out in the sun. What you may not know is that if you apply certain sunscreen sprays and then come close to a source of flame, you may risk the sunscreen catching fire and giving you a serious burn.

The Food and Drug Administration (FDA) has become aware of five separate incidents in which people wearing sunscreen spray near sources of flame suffered significant burns that required medical treatment. The specific products reported to have been used in these cases were voluntarily recalled from the market, so should no longer be on store shelves.

However, many other sunscreen spray products contain flammable ingredients, commonly alcohol. The same is true for certain other spray products, such as hairspray and insect repellants, and even some non-spray sunscreens may contain flammable ingredients. Many flammable products have a label warning against their use near an open flame.
