Precautionary statements

Keep only in original container. Keep away from combustible materials. Keep away from heat, hot surfaces, sparks, open flames and other ignition sources. No smoking. Do not breathe dust, vapor or spray mist. Wash hands and exposed skin thoroughly after handling. Do not touch eyes. Do not eat, drink, or smoke when using this product. Wear protective gloves, protective clothing, eye, and face protection. Wash contaminated clothing before reuse. Avoid release to the environment. - Disposal • Dispose of contents and container in accordance with applicable local, regional, national, and/or international regulations Physical Hazards of Significance Not Mentioned in GHS Classification • According to NFPA 400, this material is classified as a Class 2 Oxidizer • NFPA Class 2 Oxidizer (Class 2 Oxidizers will increase the burning rate of combustible materials with which they come in contact. In addition, they may cause spontaneous ignition when in contact with a combustible material) • This product becomes a fire or explosive hazard if allowed to dry. Dry sodium chlorite is a strong oxidizing agent • Contamination may start a chemical reaction with generation of heat, liberation of hazardous gases (chlorine dioxide a poisonous, explosive gas), and possible fire and explosion. Do not contaminate with garbage, dirt, organic matter, household products, chemicals, soap products, paint products, solvents, acids, vinegar, beverages, oils, pine oil, dirty rags, or any other foreign matter. Other incompatible materials which should be avoid which include oxidizers, _________________________________________________________________________________________________ BIO-TEC 25 Updated: 18-Apr-2024 Updated: Num. 08 ________________________________________________________________________________________________ reducing agents, and combustible materials. Health Hazards of Significance Not Mentioned in GHS Classification • May be harmful in contact with skin • Potential endocrine disruptor

Additional information

This material is corrosive and an oxidizer. This material is a more severe corrosive and oxidizer when dry. Dry sodium chlorite is a strong oxidizing agent. This product becomes a fire or _________________________________________________________________________________________________ BIO-TEC 25 Updated: 18-Apr-2024 Updated: Num. 08 _________________________________________________________________________________________________ explosive hazard if allowed to dry. This material's pH and oxidative action contribute to its health and physical hazards. If not stored in original container; store in corrosive resistant container constructed of materials identified in Section 7 of this SDS. Always package, store, transport and dispose of all waste and contaminated equipment in accordance with all applicable federal, state, and local health and environmental regulations. Contamination may start a chemical reaction with generation of heat, liberation of hazardous gases (chlorine dioxide a poisonous, explosive gas), and possible fire and explosion. Do not contaminate with garbage, dirt, organic matter, household products, chemicals, soap products, paint products, solvents, acids, vinegar, beverages, oils, pine oil, dirty rags, or any other foreign matter. Other incompatible materials which should be avoid which include oxidizers, reducing agents, and combustible materials. HAZARD CLASSIFICATION
