Product Name & Other Names: Caustic soda or Sodium hydroxide Solid, Flakes, Pellets.
CAS No.: 1310-73-2
EINECS EC Number: 215-185-5
Dilution, if any is with water.

Eye Contact: Check for and remove any contact lenses. In case of contact, immediately flush eye with plenty of water for at least 15 minutes. Cold water may be used. Get medical attention immediately.
Skin Contact: Immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes. Call a physician, immediately. Wash clothing before reuse.
Ingestion: If swallowed, do not induce vomiting unless directed to do so by medical personnel. Never give anything by mouth to and unconscious person. Loosen tight clothing such as a collar, tie, belt, or waistband. Get medical attention immediately.
Medical Conditions generally Aggravated by Exposure: Repeated exposure of the eyes to a low level of Sodium hydroxide dust can produce eye irritation. Repeated skin exposure can produce local skin destruction, or dermatitis. Repeated inhalation of dust can produce varying degree of respiratory irritation or lung damage.

Flash Point: NA
Fire Extinguishing Media: Adapt extinguishing media to the environment. Use water spray, alcohol-resistant foam, dry chemical or carbon dioxide.
Unusual Fire and Explosion Hazards: Flammable hydrogen gas may be produced on prolong contact with metals such as aluminum, tin lead and zinc.
Hazardous combustion products: Oxides of sodium.
Special Information: In the event of a fire, wear full protective clothing and NIOSH-approved self-contained breathing apparatus with full face piece operated in the pressure demand or other positive pressure mode. At high temperatures under fire conditions, it may produce toxic or irritating fumes. Fire-extinguishing work is done from the windward and the suitable fire-extinguishing method according to the surrounding situation is used. Uninvolved persons should evacuate to a safe place.

Personal precautions, protective equipment, and emergency procedures: Avoid breathing dust/fumes/gas/mist/vapors/spray. Use individual protective equipment (waterproof boots, suitable protective clothing, safety glasses, etc.). Eliminate any ignition sources. Restrict unprotected personnel from the area. Prevent any contact with hot surfaces. Do not approach facing the wind. Do not touch the spilled material.
Environmental precautions: Do not let the product enter drains, soil, or water sources.
Methods and materials used for containment Cleanup procedures and Storage: Do not inhale vapors, mist, or gas. Avoid dust formation. Contain spilled material. Cover with an inert, non-combustible absorbent material, (e.g. sand, earth, diatomaceous earth, vermiculite). Use a shovel to put the material into a convenient waste disposal container. Finish cleaning by spreading water on the contaminated surface and allow to evacuate as per law. Small quantities of liquid spill may be neutralized with acid solution.

Precautions for safe handling: Apply according to good manufacturing and industrial hygiene practices. Ensure proper ventilation. In case of insufficient ventilation, wear suitable respiratory equipment. Wash thoroughly after handling. Do not drink, eat, or smoke while handling. Avoid contact with skin, eyes, and clothing. Minimize dust generation. Avoid breathing dust/fumes/gas/mist/vapors/spray. Avoid contact with eyes, skin, and clothing. Keep container tightly closed. Avoid ingestion and inhalation. Use individual protective equipment (waterproof boots, suitable protective clothing, safety glasses, etc.). Prevent any contact with hot surfaces.
Conditions for safe storage, including any incompatibilities: Store in cool, dry, and ventilated area away from heat sources and protected from sunlight in tightly closed original container. Keep air contact to a minimum. Store protected from heat, sparks and ignition sources and incompatible materials. Avoid contact with skin and eyes. Avoid inhalation of dust/mist/vapor. Do not store with incompatible materials like strong oxidizing agents, acids, chlorinated hydrocarbons, metals, and organic materials. Avoid moisture. Always add the caustic to water while stirring, never the reverse. Do not store with aluminum or magnesium.

Components with workplace control parameters
Derived No Effect Level (DNEL)
Application Area: Workers, Consumers
Exposure routes: Inhalation
Health effect Long-term local effects: 1 mg/m3
USA ACGIH: 2 mg/m³ ACGIH Ceiling (mg/m³)
USA OSHA: 2 mg/m³ OSHA PEL (TWA) (mg/m³)
British Columbia: 2 mg/m³ OEL Ceiling (mg/m³)
Engineering Controls Ventilation required: Sodium hydroxide should be handled or transferred in an approved fume hood or with adequate ventilation.
Ventilation System: A system of local and/or general exhaust is recommended to keep employee exposures as low as possible. Local exhaust ventilation is generally preferred because it can control the emissions of the contaminant at its source, preventing dispersion of it into the general work area.
Personal Respirators (NIOSH Approved): For conditions of use where exposure to dust or mist is apparent and engineering controls are not feasible, a particulate respirator may be worn. For emergencies or instances where the exposure levels are not known, use a full-face positive-pressure, air-supplied respirator.
Skin Protection: Wear protective gloves and clean body-covering clothing.
Eye Protection: Use chemical safety goggles and/or full face shield where dusting or splashing of solutions is possible. Maintain eye wash fountain and quick-drench facilities in work area.
Other Control Measures: Maintain good housekeeping in work area. Dust deposits on floors and other surfaces may pick up moisture and cause the surfaces to become slippery and present safety hazards. Handle in accordance with good industrial hygiene and safety practice. Wash hands after handling.
