Burns from Air Bag Deployment

I was recently in a severe auto accident which I walked away from thanks to seat belts and air bags. However, being the passenger of the vehicle, the large air bag on my side deployed and severly "burned" and bruised both of my legs. The wounds appear to be a combination of an abrasion & a burn. They hurt like heck and Im not sure how to care for them to reduce the amount of scarring. I have kept them clean with antibiotic ointment & bandages for the last few days but I am not sure if I should leave the bandages on or let the wounds dry out. The exposure to the air is extremely painful as well as when I am standing or walking and the blood rushes to them. Any advise would be appreciated!!!
