Put a mask over your nose and mouth. If you have a respirator or mask designed to filter out small particulates, put it on immediately. If you don't have a mask, wrap a bandanna or some other piece of cloth around your nose and mouth. A shirt sleeve or a medium-sized sheet works good. Moisten it a bit if you have enough water. Apply a small amount of petroleum jelly to the inside of your nostrils to prevent drying of your mucus membranes.
