CHEMICAL IDENTIFIERS

SODIUM CHLORITE
NaClO2
Sodium Chlorite shipping info Un# 1496, CAS# 7758-19-2 Hazard Class 5.1 Oxidizer, Packaging Class II
GENERAL DESCRIPTION
A white crystalline solid. Difficult to burn, but accelerates the burning of organic substances. Forms explosive mixtures with certain combustible materials. May explode under prolonged exposure to heat or fire. Used in water purification, to bleach wood pulp, textile, fats, oils; and for many other uses.

HAZARDS
Reactivity Alerts: Explosive, Strong Oxidizer
Air & Water Reactions Soluble in water.
Fire Hazard May explode from friction, heat or contamination. Will accelerate burning when involved in a fire. May ignite combustibles (wood, paper, oil, clothing, etc.).
Can react explosively with hydrocarbons (fuels). Containers may explode when heated. Runoff may create fire or explosion hazard. (ERG, 2008)
Health Hazard  *TOXIC*  Inhalation, ingestion or contact (skin, eyes) with vapors, dusts or substance may cause severe injury, burns or death. Fire may produce irritating and/or toxic gases. Toxic fumes or dust may accumulate in confined areas (basement, tanks, hopper/tank cars, etc.). Runoff from fire control or dilution water may cause pollution. (ERG, 2008)
Reactivity Profile SODIUM CHLORITE is self-reactive. The trihydrate crystals of sodium chlorite explode on percussion. Sodium chlorite reacts with acids to form spontaneously explosive chlorine dioxide gas (ClO2). If heated above 347°F, the reaction yields enough heat to become self-sustaining, [Mellor 2 Supp. 1:573 1956]. Ammonia with chlorites produces ammonium chlorite, which is a shock-sensitive compound. Finely divided metallic or organic substances, if mixed with chlorites, are highly flammable and may be ignited on friction [Lab. Gov. Chemist 1965]. A mixture of organic matter and sodium chlorite can be extremely sensitive to heat, impact, or friction (Diox Process 1949). Sodium chlorite reacts very violently with organic materials containing divalent sulfur or with free sulfur (may ignite).
Belongs to the Following Reactive Group Inorganic Oxidizing Agents

RESPONSE RECOMMENDATIONS
Firefighting Flood with water. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible. (AAR, 2003)
Non-Fire Response Keep sparks, flames, and other sources of ignition away. Keep material out of water sources and sewers. (AAR, 2003)
Protective Clothing Wear appropriate chemical protective gloves, boots and goggles. Do not handle broken packages unless wearing appropriate personal protective equipment. Wash away any material which may have contacted the body with copious amounts of water or soap and water. Wear positive pressure self-contained breathing apparatus when fighting fires involving this material. (AAR, 2003)
First Aid Move victim to fresh air. Call 911 or emergency medical service. Give artificial respiration if victim is not breathing. Administer oxygen if breathing is difficult. Remove and isolate contaminated clothing and shoes. Contaminated clothing may be a fire risk when dry. In case of contact with substance, immediately flush skin or eyes with running water for at least 20 minutes. Keep victim warm and quiet. Ensure that medical personnel are aware of the material(s) involved and take precautions to protect themselves. (ERG, 2008)
