Green Job Hazards: Hydrogen Fuel Cells - Freeze Burns
Workers may also be exposed to freeze burns when liquid hydrogen comes into contact with the skin. Hydrogen in the liquid form can be very cold -- hydrogen becomes a liquid below -423°F. To protect workers from the freeze burn hazards, the containers should be double-walled and vacuum-jacketed, and should designed to vent hydrogen safely in gaseous form if either the outer or inner wall experiences a leak.
