Since calcium carbonate is nontoxic, calcium ammonium nitrate is less toxic than a comparable amount of ammonium nitrate. Symptoms of methemoglobinemia and hemolysis include bluish coloring especially of lips or nail beds, shortness of breath, dizziness, fatigue, and headache.Ĭalcium ammonium nitrate is a mixture of calcium carbonate and ammonium nitrate. It might also cause conditions called methemoglobinemia (impairment of the oxygen-carrying ability of red blood cells) and hemolysis (destruction of red blood cells). This can lower blood pressure and reduce the amount of blood flowing to body organs. Ammonium nitrate can cause dilation of blood vessels. Of these, the most toxic ingredient if swallowed is ammonium nitrate. The chemical reactors in these ice packs are typically ammonium nitrate, calcium ammonium nitrate, or urea. When the bag is squeezed, the water interacts with the chemical to start a reaction that lowers the temperature of the water to almost freezing. These are filled with water and a chemical reactor. The most concerning type of ice pack is the instant ice pack. Depending on the type of ice pack, results of exposure can range from nontoxic to serious. These are stored at room temperature and only turn cold when squeezed. There are also one-time use "instant" ice packs, which can be found in many first-aid kits. Other ice packs turn into solids when frozen but are soft and squishy when thawed. Some are in cute shapes with soft, gel-like beads in them. They come in many forms and contain different ingredients depending on the type of ice pack. Ice packs are found in millions of homes as they are used for a wide variety of purposes such as icing an injury and keeping food cold.
