Water reactive. Reacts violently with water to give off corrosive dust and flammable hydrogen gas. Elevated temperatures, above melting point, can result in spontaneous ignition in humid air. Corrosive to eyes, skin, nose, throat and stomach. Can be handled in open atmosphere at room temperature, either coated with mineral oil or where relative humidity is maintained below 50%. To maintain best quality, humidity level of less than 2% is recommended. Wear safety glasses or goggles and dry rubber gloves. Store in original unopened shipping package. Once opened, store in argon atmosphere or mineral oil. Keep away from water, humid air, acids and oxidizing materials. Keep way from heat, sparks and flame. 9.4 Shipping Limitations Shipments of lithium magnesium foil are described as "Metallic substance, water-reactive, N.O.S.(lithium magnesium alloy), UN3208, 4.3 PGI”.
