The Uses of Selenious Acid:

The major use is in protecting and changing the color of steel, especially steel parts on firearms. Another use for selenious acid is the chemical darkening and patination of copper, brass and bronze, producing a rich dark brown color that can be further enhanced with mechanical abrasion. It is used in organic synthesis as an oxidizing agent. Selenious acid is a key component of the Mecke reagent used for drug checking. Selenious acid can supply the trace element indicated in people as a source of selenium.

Section 3: Composition and Information on Ingredients

Product Name & Other Names: Selenious acid or Selenous acid
CAS No.: 7783-00-8

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 elevated 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.

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. Finish cleaning by spreading water on the contaminated surface and allow to evacuate as per law.

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. 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. 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. Do not store with incompatible materials like strong oxidizing agents, organic materials, powdered metals.
