Dry ice is classified as a miscellaneous hazard (Class 9) during transportation by DOT and IATA.<\/p>\n<p>Hazards associated with dry ice include risk of explosion and suffocation in an enclosed space, and risk of severe frostbite injury when handled. Dry ice is so cold it will freeze the blood inside your skin if handled with bare hands. For these reasons, many carriers have now restricted or prohibited the distribution of parcels containing dry ice, and the couriers that do still accept it will apply a surcharge to the shipping cost.<\/p>\n<p><span style=\"color: #3366ff;\">HydroFreeze\u2122<\/span>\u00a0and <span style=\"color: #3366ff;\">HydroFreeze\u2122<strong><em>+<\/em><\/strong><\/span> eliminate these hazards and offer a safer and competitive alternative \u2013 think of it as a regular ice pack\u2026 just a cooler version of it!
