I was driving on the highway and was rear ended by another vehicle which lifted the back end of my truck from the ground. Both side air bags deployed. I was wearing a hoodie at the time and the airbag deployment caused my hoodie to catch on fire. There was not an open flame for me to know it was burning. Instead, it smoldered and burnt my hoodie material. I could feel the underside of my arm stinging and the holes in my sleeve, but believed that it was a result of the airbag hitting my arm and causing essentially a bad carpet burn. However, this caused second degree burns to the bottom side of my arm near my arm pit. I discovered after the incident that airbag deployment is assisted by gunpowder. I am not sure if this is what caused my hoodie to catch fire. I also discovered that 2021-2022 Rams recently had a recall on Side Airbags due to improperly compressed air. My truck is a 2019 however, so I'm not sure if that recall should be expanded to include additional years.
