Safety and Handling

1. Personal Protective Equipment (PPE):
   • Gloves: Always wear nitrile or rubber gloves when handling MoO₃ to avoid skin contact.
   • Eye Protection: Use safety goggles or a face shield to protect eyes from dust or powder exposure.
   • Respiratory Protection: Use a dust mask or respirator when handling MoO₃ powder to avoid inhalation of particles.
   • Protective Clothing: Wear lab coats or protective aprons to protect clothing and skin from exposure.
2. Handling:
   • MoO₃ should be handled in a well-ventilated area to prevent inhalation of dust.
   • When working with large quantities, use a fume hood to prevent exposure to fumes or airborne particles.
   • Avoid direct contact with MoO₃ as it is a strong oxidizer and may react with other substances.
3. Storage:
   • Store Molybdenum Trioxide in airtight containers to protect it from moisture, as it may form molybdic acid when exposed to water.
   • Keep it in a cool, dry environment away from oxidizing agents and flammable materials.
   • Ensure the storage area is well-ventilated and free from sources of ignition.
4. First Aid:
   • Inhalation: If inhaled, move the individual to fresh air immediately. Seek medical attention if symptoms such as coughing or difficulty breathing occur.
   • Skin Contact: Wash affected areas with soap and water. If irritation persists, seek medical attention.
   • Eye Contact: Flush eyes with plenty of water for at least 15 minutes and seek medical attention if irritation persists.
   • Ingestion: If swallowed, do not induce vomiting. Rinse the mouth with water and seek medical attention immediately.
5. Hazards:
   • Inhalation: May cause irritation to the respiratory tract. Prolonged exposure to dust may lead to respiratory issues.
   • Skin Contact: Can cause irritation on prolonged contact.
   • Fire Hazard: Molybdenum Trioxide is not flammable but may present a fire hazard if mixed with flammable substances.
