Avoid breathing fume, gas, vapors, spray. Use only outdoors or in a well-ventilated area. Response Immediately call a POISON CENTER or doctor/physician. IF SWALLOWED: Rinse mouth. Do NOT induce vomiting. IF ON SKIN (OR HAIR): Take off immediately all contaminated clothing. Rinse skin with water/shower. Wash contaminated clothing before reuse. IF INHALED: Remove person to fresh air and keep comfortable for breathing. IF IN EYES: Rinse cautiously with water for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing. Absorb spillage to prevent material damage. Storage Store locked up. Store in a well-ventilated place. Keep container tightly closed. Store in corrosive resistant container with a resistant inner liner. Disposal Dispose of contents/container in accordance with local/regional/national/international regulations. Hazard(s) not otherwise No OSHA defined hazard classes. classified (HNOC) Other hazards which do not result in classification: Contact with most metals will generate flammable hydrogen gas. Contact with water will generate considerable heat. Reacts vigorously, violently or explosively with many organic and inorganic chemicals, such as strong acids, acid chlorides, acid anhydrides, ketones, glycols and organic peroxides. Chronic skin contact with low concentrations may cause dermatitis. Supplemental Not applicable. information Page 2 of 17 Issue Date: 11/18/2020 Sodium Hydroxide Solution 3. Composition/Information on Ingredients Chemical name Common name and synonyms CAS number Conc. % By Weight Sodium Hydroxide Caustic Soda, Lye (Sodium), 1310-73-2 18 - < 70 w/w% Sodium Hydrate, Soda Lye Dihydrogen oxide Water 7732-18-5 Balance Chemical name of impurities, stabilizing solvents and/or additives: None 4. First-Aid Measures Inhalation Move to fresh air. If breathing is difficult, trained personnel should give oxygen. If breathing stops, provide artificial respiration. Induce artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device. Immediately call a POISON CENTER or doctor/physician. Skin Contact Take off immediately all contaminated clothing. Immediately flush skin with running water for at least 20 minutes, or until the feeling of slipperiness disappears. Cover wound with sterile dressing. Do not rub area of contact. Wash contaminated clothing before reuse. Leather and shoes that have been contaminated with the solution may need to be destroyed. Immediately call a POISON CENTER or doctor/physician. Eye Contact Immediately flush eyes with plenty of water for at least 20 minutes, holding the eyelids open. Remove contact lenses, if present and easy to do. Continue rinsing. Take care not to rinse contaminated water into the unaffected eye or onto the face. Immediately call a POISON CENTER or doctor/physician. Ingestion Rinse mouth. Do NOT induce vomiting. Never give anything by mouth to a victim who is unconscious or is having convulsions. If victim can swallow, have him/her drink one cup of water to dilute material in stomach. If vomiting occurs naturally, repeat administration of water. Immediately call a POISON CENTER or doctor/physician. Most important Inhalation of mists can cause severe respiratory irritation. Symptoms may symptoms/effects, include coughing, choking and wheezing. acute and delayed Inhalation could result in pulmonary edema (fluid accumulation). Symptoms of pulmonary edema (chest pain, shortness of breath) may be delayed. Direct skin contact may cause corrosive skin burns, deep ulcerations and possibly permanent scarring. Corrosive to the eyes and may cause severe damage including blindness. Symptoms may include stinging, tearing, redness, swelling, and blurred vision. May cause severe irritation and corrosive damage in the mouth, throat Page 3 of 17 Issue Date: 11/18/2020 Sodium Hydroxide Solution and stomach. Symptoms may include abdominal pain, vomiting, burns, perforations, bleeding and eventually death. Indication of immediate Immediate medical attention is required. Causes chemical burns. Symptoms medical attention and may be delayed. special treatment needed General information Ensure that medical personnel are aware of the material(s) involved, and take precautions to protect themselves. 5. Fire-Fighting Measures Suitable extinguishing Use extinguishing measures that are appropriate to local circumstances and media the surrounding environment. Use as appropriate: Water Spray or Fog. Alcohol resistant foam. Dry chemical powder. Use water with caution. Contact with water will generate considerable heat. Do not apply water directly to sodium hydroxide since it can generate significant heat and cause spattering. Unsuitable Carbon dioxide (CO2). Use chemical extinguishing agents with caution. Some extinguishing media chemical extinguishing agents may react with this material. Specific hazards arising Not considered flammable. Contact with most metals will generate from the chemical flammable hydrogen gas. Contact with water will generate considerable heat. The heat that is generated may be sufficient enough to ignite nearby combustible materials. Reacts vigorously, violently or explosively with many organic and inorganic chemicals, such as strong acids, acid chlorides, acid anhydrides, ketones, glycols and organic peroxides. Toxic fumes, gases or vapours may evolve on burning. Special protective Firefighters should wear proper protective equipment and self-contained equipment and breathing apparatus with full face piece operated in positive pressure mode. precautions for A full-body chemical resistant suit should be worn. firefighters Firefighting Fight fire with normal precautions from a reasonable distance. Evacuate the equipment/instructions area promptly. Move containers from fire area if you can do so without risk. Use water spray to cool unopened containers. Do not allow run-off from firefighting to enter drains or water courses. Dike for water control. Use standard firefighting procedures and consider the hazards of other involved materials. Specific methods When moist, sodium hydroxide can react with metals, such as aluminum, tin and zinc, to form flammable and explosive hydrogen gas. Toxic sodium oxide fumes can be generated by thermal decomposition at elevated temperatures.

Move containers from fire area if you can do so without risk. Use water spray to cool unopened containers. Do not allow run-off from firefighting to enter drains or water courses. Dike for water control. 6. Accidental Release Measures Personal precautions, Immediately evacuate personnel to safe areas. Keep unnecessary protective equipment personnel away. Keep people away from and upwind of spill/leak. Wear and emergency appropriate protective equipment and clothing during clean-up. Do not procedures touch damaged containers or spilled material unless wearing appropriate protective clothing. Ventilate closed spaces before entering them. For personal protection, see section 8 of the SDS. Methods and materials Ventilate the area. Remove sources of ignition. Stop leak if you can do so for containment and without risk. Absorb spillage to prevent material damage. Use a non- cleaning up combustible material like vermiculite, sand or earth to soak up the product and place into a container for later disposal. Water
