Section 4. First Aid & Procedure
Always get medical attention after the first aid is over.
Ingestion: Induce vomiting immediately as directed by medical personnel. Never give anything by mouth to an unconscious person. Get medical attention.
Skin: Immediately flush skin with plenty of water for at least 15 minutes. Remove and wash contaminated clothing and shoes before reuse. Get medical attention if irritation develops.
Eyes: Immediately flush eyes with plenty of water for 15 minutes, occasionally lifting upper and lower eyelids. Hold eyelids apart during irrigation. Get medical attention.
Inhalation: Remove person to fresh air. If breathing is difficult, give oxygen. If not breathing administer artificial respiration. Get medical attention.
Section 5. Fire Fighting Measures
Flash Point: N/A
Extinguishing Medium: Water spray, alcohol-resistant foam, dry chemical or carbon dioxide.
Fire Fighting Instructions: Use suitable protective equipment for surrounding fire.
Extinguishing Media Not recommended: Avoid using solid water jet as it may scatter the fire.
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.
Section 6. Spills and Disposals
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.). Do not approach facing the wind.
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.
Section 7. Handling and Storage
Precautions for safe handling: Apply according to good manufacturing and industrial hygiene practices. Avoid prolonged or repeated exposure. Ensure proper ventilation. In case of insufficient ventilation, wear suitable respiratory equipment. 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 ingestion and inhalation. Use individual protective equipment (waterproof boots, suitable protective clothing, safety glasses, etc.).
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.
Section 8. Exposure Controls & Personal Protection
Exposure Limits for Selenious acid:
OSHA PEL: 0.2 mg/m3.
ACGIH TLV: 0.2 mg/m3 (TWA).
Engineering Controls: Use adequate exhaust ventilation to keep airborne concentrations below the allowable exposure limit.
Ventilation System: A system of local and/or general exhaust is recommended to keep employee exposures as low as possible.
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.
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. Handle in accordance with good industrial hygiene and safety practice. Wash hands after handling.
