(EPA Standard Operating SafetyGuidelines, OSHA 29 CFR 1910.120, NFPA 472)A refrigerated, liquefied gas that has a boiling point colder than -90oC(-130oF) at atmospheric pressure.Produces significant toxic gas when it comes in contact withwater.DecontaminationDry chemicalEdemaERPG(s)ERPG-1ERPG-2ERPG-3Flammable liquidThe removal of dangerous goods from personnel and equipment to theextent necessary to prevent potential adverse health effects. Alwaysavoid direct or indirect contact with dangerous goods; however, if contactoccurs, personnel should be decontaminated as soon as possible. Sincethe methods used to decontaminate personnel and equipment differfrom one chemical to another, contact the chemical manufacturer,through the agencies listed on the inside back cover, to determine theappropriate procedure. Contaminated clothing and equipment should beremoved after use and stored in a controlled area (warm/contaminationreduction/yellow/limited access zone) until cleanup procedures can beinitiated. In some cases, protective clothing and equipment cannot bedecontaminated and must be disposed of in a proper manner.A preparation designed for fighting fires involving flammable liquids,pyrophoric substances and electrical equipment. Common types containsodium bicarbonate or potassium bicarbonate.The accumulation of an excessive amount of watery fluid in cells andtissues. Pulmonary edema is an excessive buildup of water in the lungs,for instance, after inhalation of a gas that is corrosive to lung tissue.Emergency Response Planning Guideline(s).
