It does cause violent polymerization of acrylaldehyde or ethyleneimine. This weakly acidic material will react with alkaline materials to form carbonates and bicarbonates. An explosion can occur when CO2 contacts mixtures of sodium peroxide with aluminum or magnesium. Dry ice can form shock sensitive mixtures with sodium, potassium, or sodium-potassium alloy. Forms solid DRY ICE when spilled.
Dry ice is very cold, void contact with skin.
Ventilate enclosed areas to prevent formation of oxygen deficient atmosphere caused by the sublimation of the dry ice. Use self-contained breathing apparatus in oxygen deficient atmospheres. Cartridge respirators will not reduce or remove CO2 from an atmosphere. Use of a respirator in an atmosphere with dangerous levels of CO2, may result in asphyxiation. Loose fitting, leather or synthetic.
