NTP – Not Listed IARC Monograph – No OSHA Regulated – No
Signs and Symptoms of Overexposure:

Inhalation: May cause sneezing, coughing, difficult to breath and irritation of the mucous membrane of the respiratory tract.

Dermal/Eye Contact: Dermal: May cause irritation, itching and dermatitis. Eye: May cause burning sensation, irritation, redness and watering of the eyes if coming in contact.
Other: In Compounds: Highly toxic via subcutaneous and moderately toxic via oral routes. Symptoms of acute indium intoxication are anorexia, localized convulsive motions, hind-leg paralysis, pulmonary edema, necrotizing pneumonia, and renal and hepatic damage with resultant dysfunction. Chronic indium intoxication leads to weight loss, poor growth, and extensive necrotic damage to the liver and kidneys.

Phosphides: Phosphides are particularly dangerous because they tend to decompose to phosphine upon contact with moisture or acids. Phosphine is a very toxic gas. It appears to cause, chiefly, a depression of the CNS and irritation of the lungs. Inhalation of phosphine causes restlessness, followed by tremors, fatigue, slight drowsiness, nausea, vomiting and frequently, severe gastric pain and diarrhea. There is often headache, thirst, dizziness, oppression in the chest and burning substernal pain; later the patient may become dyspneic and develop cough and sputum. Coma or convulsions may precede death. Chronic poisoning, characterized by anemia, bronchitis, gastrointestinal disturbances and visual, speech and motor disturbances may result from continued exposure to low concentrations.

Emergency and First Aid Procedures: Treat symptomatically

Eyes: Flush eyes with lukewarm water for 15 minutes. Seek medical attention.

Skin: Brush material off of skin. Wash affected area with soap and water. Seek medical attention.

Inhalation: Remove victim to fresh air. Administer oxygen if breathing is difficult. Seek medical attention

Ingestion: Give 1~2 glasses of milk or water and induce vomiting. Seek immediate medical attention.

Section 7: Precautions for Safe Handling and Use

Steps to be Taken in Case Material is Released or Spilled: Wear a self-contained breathing apparatus and full protective clothing. Isolate the area where the spill occurred and insure that proper ventilation is available. Vacuum up spill using a high efficiency unit and place in a container for proper disposal. Take care not to raise dust. Insure that water/moisture is kept out of the area.

Waste Disposal Method: In accordance with Local, State and Federal Waste Disposal Regulations.
Section 8: Control Measures

Respiratory Protection (Specify Type): Wear NIOSH-approved dust mist-fume cartridge respirator

Ventilation: Local Exhaust: Maintain exposure below TLV level for P4 & In

Protective Gloves: Neoprene; Eye Protection: Safety Glasses

Other Protective Clothing or Equipment: Wear protective clothing to prevent contamination of skin and clothes.

Work/Hygienic Practices: Wash thoroughly after handling; Store in tightly closed containers, in a cool, dry place.
