Plain and simple. Pop the blisters with a sterile pin or sharp object. Allow it to drain, then soak the hand in salt-water to loosen up the dead skin. Wash the area contsantly and use paper towels to absorb the weeping. Apply Hydrogen peroxide and a topical ointment before bed. I would not recommend gauze or anything to prevent air from contact to the wound unless your handeling anything that could cause infection. Common scence. Keep it cleaned and allow air to it for fast healing.
