Composition/information on ingredients Mixtures Chemical name Common name and synonyms CAS number % Sodium Bisulfite (aqueous Solution) 7631-90-5 25 Other components below reportable levels 75 *Designates that a specific chemical identity and/or percentage of composition has been withheld as a trade secret. 4. First-aid measures Inhalation If breathing is difficult, remove to fresh air and keep at rest in a position comfortable for breathing. Oxygen or artificial respiration if needed. Do not use mouth-to-mouth method if victim inhaled the substance. Induce artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device. If experiencing respiratory symptoms: Call a POISON CENTER or doctor/physician. Skin contact Remove contaminated clothing immediately and wash skin with soap and water. Call a physician or poison control center immediately. Chemical burns must be treated by a physician. Wash contaminated clothing before reuse. Eye contact Immediately flush eyes with plenty of water for at least 15 minutes. Remove contact lenses, if present and easy to do. Continue rinsing. Call a physician or poison control center immediately. Ingestion Call a physician or poison control center immediately. Rinse mouth. Do not induce vomiting. If vomiting occurs, keep head low so that stomach content doesn't get into the lungs. Most important Burning pain and severe corrosive skin damage. Causes serious eye damage. Symptoms may symptoms/effects, acute and include stinging, tearing, redness, swelling, and blurred vision. Permanent eye damage including delayed blindness could result. Difficulty in breathing. Indication of immediate Provide general supportive measures and treat symptomatically. Chemical burns: Flush with water medical attention and special immediately. While flushing, remove clothes which do not adhere to affected area. Call an treatment needed ambulance. Continue flushing during transport to hospital. Keep victim warm. Keep victim under observation. Symptoms may be delayed. General information Ensure that medical personnel are aware of the material(s) involved, and take precautions to protect themselves. Show this safety data sheet to the doctor in attendance. Wash contaminated clothing before reuse. 5. Fire-fighting measures Suitable extinguishing media Water fog. Foam. Dry chemical powder. Carbon dioxide (CO2). Unsuitable extinguishing Do not use water jet as an extinguisher, as this will spread the fire. media Specific hazards arising from Not applicable. the chemical Special protective equipment Wear suitable protective equipment. and precautions for firefighters Fire fighting Move containers from fire area if you can do so without risk. equipment/instructions Specific methods Use standard firefighting procedures and consider the hazards of other involved materials. General fire hazards No unusual fire or explosion hazards noted. 6. Accidental release measures Personal precautions, Keep unnecessary personnel away. Keep people away from and upwind of spill/leak. Wear protective equipment and appropriate protective equipment and clothing during clean-up. Do not breathe mist or vapor. Do emergency procedures not touch damaged containers or spilled material unless wearing appropriate protective clothing. Ensure adequate ventilation. Local authorities should be advised if significant spillages cannot be contained. For personal protection, see section 8 of the SDS. Methods and materials for Large Spills: Stop the flow of material, if this is without risk. Dike the spilled material, where this is containment and cleaning up possible. Cover with plastic sheet to prevent spreading. Absorb in vermiculite, dry sand or earth and place into containers. Following product recovery, flush area with water. Small Spills: Wipe up with absorbent material (e.g. cloth, fleece). Clean surface thoroughly to remove residual contamination. Never return spills to original containers for re-use. For waste disposal, see section 13 of the SDS. Environmental precautions Avoid discharge into drains, water courses or onto the ground. 7. Handling and storage Precautions for safe handling Provide adequate ventilation. Do not breathe mist or vapor. Do not get in eyes, on skin, or on clothing. Avoid prolonged exposure. Do not taste or swallow. When using, do not eat, drink or smoke. Wear appropriate personal protective equipment. Wash hands thoroughly after handling. Observe good industrial hygiene practices. Conditions for safe storage, Store locked up. Store in original tightly closed container. Store in a well-ventilated place. Store including any incompatibilities away from incompatible materials (see Section 10 of the SDS). 8. Exposure controls/personal protection Occupational exposure limits US. ACGIH Threshold Limit Values Material Type Value Sodium Bisulfite 25% TWA 5 mg/m3 Components Type Value Sodium Bisulfite (aqueous TWA 5 mg/m3 Solution) (CAS 7631-90-5) US. NIOSH: Pocket Guide to Chemical Hazards Material Type Value Sodium Bisulfite 25% TWA 5 mg/m3 Components Type Value Sodium Bisulfite (aqueous TWA 5 mg/m3 Solution) (CAS 7631-90-5) Biological limit values No biological exposure limits noted for the ingredient(s). Appropriate engineering Good general ventilation (typically 10 air changes per hour) should be used. Ventilation rates controls should be matched to conditions. If applicable, use process enclosures, local exhaust ventilation, or other engineering controls to maintain airborne levels below recommended exposure limits. If exposure limits have not been established, maintain airborne levels to an acceptable level. General ventilation normally adequate. Eye wash facilities and emergency shower must be available when handling this product. Individual protection measures, such as personal protective equipment Eye/face protection Wear safety glasses with side shields (or goggles). In the absence of engineering controls, wear 3M 6000 Series Full-Face Respirator or NIOSH approved equivalent. Utilize multi-purpose organic vapor and acid gas cartridge (3M 6006) or NIOSH approved equivalent. Label color on cartridge should be olive green. Skin protection Hand protection Wear appropriate chemical resistant gloves. Suitable gloves can be recommended by the glove supplier. Other Wear appropriate chemical resistant clothing. Use of an impervious apron or protective suit is recommended. Respiratory protection In case of insufficient ventilation, wear suitable respiratory equipment. In case of insufficient ventilation, wear suitable respiratory equipment. Where risk assessment shows air-purifying respirators are appropriate, as a back-up to or in the absence of engineering controls, use 3M 6000 Series Full-Face Respirator or NIOSH approved equivalent. Utilize multi-purpose organic vapor and acid gas cartridge (3M 6006) or NIOSH approved equivalent. Label color on approved cartridges is universally olive color. If the respirator is the sole means of protection, a full-face-respirator is mandatory. Thermal hazards Wear appropriate thermal protective clothing, when necessary. General hygiene Keep away from food and drink. Always observe good personal hygiene measures, such as considerations washing after handling the material and before eating, drinking, and/or smoking. Routinely wash work clothing and protective equipment to remove contaminants. Contaminated work clothing should not be allowed out of the workplace. 9.
