Arsenic Trioxide

Arsenic Trioxide, also known as White Arsenic, is a highly toxic and odorless white crystalline powder or vitreous solid. It is one of the most important arsenic compounds and is used in various industries despite its toxicity. Arsenic Trioxide is soluble in water, creating an acidic solution, and is known for its historical use as a pesticide and in the treatment of some forms of cancer.

Applications:

• Wood Preservation: Used in the manufacture of chromated copper arsenate (CCA) for wood treatment to prevent rot and insect infestation.
• Glass Manufacturing: Used as a decolorizing and refining agent in the production of specialty glass.
• Pharmaceuticals: Arsenic Trioxide is used in small, controlled doses for the treatment of acute promyelocytic leukemia (APL).
• Pesticides: Historically used as a pesticide and rodenticide, though its use is now heavily restricted due to its toxicity.
• Chemical Synthesis: Employed in the production of other arsenic compounds and in research.

Handling and Safety:

• Personal Protective Equipment (PPE): Use gloves, eye protection, and protective clothing to prevent skin contact. Work in a well-ventilated area or fume hood to avoid inhalation.
• Inhalation: Avoid inhaling dust or fumes. Use appropriate respiratory protection if airborne concentrations are a concern.
• Skin Contact: Avoid direct skin contact. If exposed, wash immediately with plenty of water and seek medical attention.
• Spills: Carefully collect and contain spills using a vacuum or wet methods to prevent dust generation. Dispose of waste properly as hazardous material.
• Disposal: Dispose of arsenic trioxide waste in accordance with local, national, and international regulations.

Storage:

• Temperature: Store in a cool, dry, and well-ventilated area, away from heat sources.
• Containers: Keep in tightly closed containers made of materials that do not react with arsenic trioxide. Ensure the containers are clearly labeled with hazard warnings.
• Separation: Store separately from incompatible materials such as strong acids, reducing agents, and flammable substances.
• Environmental Protection: Ensure storage is in an area with secondary containment to prevent release into the environment. Arsenic trioxide is highly toxic to aquatic and terrestrial organisms.
