First-aid measures
NEED OF MEDICAL ATTENTION UrgentSKIN CONTACT Wash the area affected with plenty of water for at least 15 minutes, removing soiled clothing and shoes. Seek immediate medical attention.EYE CONTACT Wash eyes with plenty of water for at least 30 minutes. Seek immediate medical attention.CONTACT WITH CLOTHING Remove clothing immediately. Submerge in water to prevent the possibility of a fire. Wash shoes with water .INGESTION Do not induce vomit. If conscious, give water on demand and seek immediate medical attention. If unconscious, maintain the patient at rest and warm, and seek immediate medical attention.INHALATION In the event of formation of chlorine dioxide, move the patient to a well ventilated place, lying flat and at rest. If the affected person stops breathing, give artificial respiration. If breathing with difficulty, give oxygen. Always seek medical help.SPECIAL MEASURES TO BE AVAILABLE IN THE WORKPLACE Safety showers and eye-wash.
Fire-fighting measures
SUITABLE EXTINGUISHING MEDIA:A lot of water. Form curtains of water to absorb the gases that are generated in the combustion.Keep containers and deposits cool, spraying them with water if exposed to the fire.If feasible, remove the combustible agent.Remove the containers from the area of fire, if this does not entail risk.EXTINGUISHING MEDIA WICH MUST NOT BE USED:CO2 powder (powdered dry ice), foam or fire blanket.SPECIAL EXPOSURE HAZARDS ARISING FROM THE SUBSTANCE, COMBUSTION PRODUCTS:The product is not flammable or explosive. If it reaches 175 °C it decomposes to chlorine and chlorate.Subsequent decomposition of the chlorate produces oxygen which may give rise to the explosion or bursting of closed containers.SPECIAL PROTECTIVE EQUIPMENT FOR FIRE-FIGHTERS:Self-contained breathing equipment. Individual protective equipment (gloves and suitable clothing).Seek emplacement with your back against the wind.
Accidental release measures
PERSONAL PRECAUTIONS:Avoid contact with the eyes, skin and clothing. Do not act without appropriate protective equipment. ENVIRONMENTAL PRECAUTIONS:Recover the whole product that is possible in a clean dry plastic or metallic container.Following product recovery, flush area with water.Notify the proper authorities.METHODS FOR CLEANING UP:Contain spill using noncombustible material Duch as vermiculite, sand or earth.Take the absorbent products to a safe storage for treatment by expert personnel in handling the product or an authorised waste manager.
Handling and storage
HANDLING:Do not smoke, eat or drink when handling the product. Avoid the formation of sparks.Maintain storage and work areas totally clean, devoid of any trace of foreign or incompatible products.Before handling the product, make sure that the containers, vessels and tanks to be used are clean, dry and appropriate for the intended use. Do not return the product (nor samples) to containers or tanks (risk of decomposition).Avoid mixing with incompatible products (acids, acid materials, combustible materials, oils, greases, etc).Containers shall be properly closed and appropriately labelled.Avoid dust formation during handling. Avoid contact with the skin, eyes and clothing.Always use the recommended protective clothing.STORAGE:Recommended materials: for containers: For materials in contact with the product use: polyester, PVC, Stainless steel, polyester or coated steel.Incompatible materials :Wood, Rubber, Aluminium, Copper and Alloys.Storage conditions: Keep in a dry place away from heat sources.Special conditions:. Keep the product separated from flammables, combustibles, acids and organics.Avoid direct sunlight.Applicable regulations: COUNCIL DIRECTIVE 96/82/EC of 9 December 1996 on the control of major-accident hazards involving dangerous substances.SPECIFIC USES:In the generation of chlorine dioxide, its concentration shall be controlled, as it is explosive at concentrations greater than 8% by volume in air.

Exposure controls / personal protection
EXPOSURE LIMIT VALUES:VLA-ED 0,1 ppm 0,28 mg/m3 VLA-EC- 0,3 ppm (INSHT ). (as ClO2)TLV-TWA 0,1 ppm 0,28 mg/m3 STEL-C 0,3 ppm (ACGIH) (as ClO2)Particulates, nor otherwise regulated:TLV-TWA- Total dust 10 mg/m3Respirable dust 3 mg/m3 (ACGIH 2005)EXPOSURE CONTROLS:Occupational exposure controls:Respiratory protection:In the event of emission of sodium chlorite powder, use mask with a dust filter (EN 143 P2 or P3)In the event of formation of chlorine dioxide use breathing protection mask with filter for inorganic gases B (Chlorine) for low concentrations (EN 136), for higher concentrations use self-contained breathing equipment (EN137).Hand protection:Gloves for chemical hazards, PVC type (do not use leather or natural rubber) (EN 374)Eye protection:Wear chemical safety goggles (EN 166)If the face is at risk as well as the eyes, a protective shield must also be worn (EN 166).Skin protection:Anti-acid suit. Do not use cotton, leather or natural rubber.Environmental exposure controls:Keeps dust abatement run-off water from reaching drains and/or surface waters.Avoid the emission of dust to the atmosphere.Measurement system: Control of dust emission.
Stability and reactivity
CONDITIONS TO AVOID:Heating, sun light.MATERIALS TO AVOID:Acids, acid substances (aluminum sulphate, aluminum chloride, ferric chloride..), wood, cellulose, grease, cotton.HAZARDOUS DECOMPOSITION PRODUCTS:The product decomposes into chlorine dioxide and oxygen under heating and direct sun-light, with risk of bursting of containers.In contact with acid materials (Acids, aluminium polychloride, aluminum sulphate, ferric chloride, etc.) chlorine dioxide is formed, with risk of explosion.Violent exothermic reaction, development of heat with reducing materials (sodium sulphite).Potentially explosive reaction with combustible materials (wood, cellulose, grease, cotton...)
Disposal considerations
Disposal of the product, contaminated packaging and waste. Spent containers shall be rinsed to remove all remaining product.Dilute the product with abundant water, avoiding the presence of solids which it may ignite (clothing, paper, wood, etc).Take into account considerations stated in previous sections regarding incompatibilities.Consult applicable European Community, National and local provisions relative to the appropriate elimination of this material and empty containers thereof.
