If there’s any cloth or paper accessible, wrap the injury and try to hold the cut closed. Grab some water if you can and head outside if you can’t contact anyone. Do you live in a populated area? Call for help if you do!

If… if the bleeding is really, really bad, you may need to apply a tourniquet in order to stop the bleeding. But you could lose the limb if you do, so be very careful! That’s a last resort!
