| SECTION 3: Hazards Identification | |
|---|---|
| Emergency Overview: | Extremely destructive to the upper respiratory tract, eyes and skin. Material hydrolyzes in contact with moisture releasing corrosive hydrogen iodide fumes. |
| Primary Routes of Exposure: | Ingestion, inhalation, skin, eyes |
| Eye Contact: | Liquid and vapors will cause burns to the eyes and blindness. |
| Skin Contact: | Corrosive to skin. Contact will lead to redness, pain, blistering, ulceration, and scar formation. |
| Inhalation: | Inhalation of choking fumes will result in chemical burning of the respiratory tract, chemical pneumonitis and pulmonary edema. |
| Ingestion: | Ingestion is unlikely due to pungent choking odor. Causes burns to the gastrointestinal system. |
| Acute Health Effects: | May be harmful if swallowed, inhaled or absorbed through skin. Material is extremely destructive to tissue of the mucous membranes, upper respiratory tract, skin and eyes. |
| Chronic Health Effects: | Chronic ingestion of iodides may produce iodism. Symptoms include skin rash, running nose, headache and irritation of mucous membranes. |
| NTP: | No |
| IARC: | No |
| OSHA: | No |
| SECTION 4: First Aid Measures | |
|---|---|
| Eye Exposure: | Immediately flush the eyes with copious amounts of water for at least 10-15 minutes. A victim may need assistance in keeping their eye lids open. Get immediate medical attention. |
| Skin Exposure: | Wash the affected area with water. Remove contaminated clothes if necessary. Seek medical assistance if irritation persists. |
| Inhalation: | Remove the victim to fresh air. Closely monitor the victim for signs of respiratory problems, such as difficulty in breathing, coughing, wheezing, or pain. In such cases seek immediate medical assistance. |
| Ingestion: | Seek medical attention immediately. Keep the victim calm. Give the victim water (only if conscious). Induce vomiting only if directed by medical personnel. |
| SECTION 5: Fire Fighting Measures | |
|---|---|
| Flash Point: | not applicable |
| Autoignition Temperature: | none |
| Explosion Limits: | none |
| Extinguishing Medium: | none required |
| Special Fire Fighting Procedures: | If involved in a fire, fire fighters should be equipped with a NIOSH approved positive pressure self-contained breathing apparatus and full protective clothing. |
| Hazardous Combustion and Decomposion Products: | If involved in a fire this material may emit corrosive hydrogen iodide fumes. |
| Unusual Fire or Explosion Hazards: | No unusual fire or explosion hazards. |
| SECTION 6: Accidental Release Measures | |
|---|---|
| Spill and Leak Procedures: | Small spills can be neutralized with powdered sodium bicarbonate, lime, or calcium carbonate and swept up. Large spills in areas not adequately ventilated will require an evacuation of site. Emergency response teams will require self-contained breathing apparatus. |
| SECTION 7: Handling and Storage | |
|---|---|
| Handling and Storage: | Store material in a tightly sealed bottle away from moisture. If possible, handle material in an efficient fume hood. Prolonged exposure to the atmosphere may lead to degradation of the product. |
| SECTION 8: Exposure Controls and Personal Protection | |
|---|---|
| Eye Protection: | Always wear approved safety glasses when handling a chemical substance in the laboratory. |
| Skin Protection: | Wear protective clothes and gloves. Consult with glove manufacturer to determine the proper type of glove. |
| Ventilation: | If possible, handle the material in an efficient fume hood. |
| Respirator: | In the absence of adequate ventilation a respirator should be worn. The use of a respiratory requires a Respirator Protection Program to be in compliance with 29 CFR 1910.134. |
| Additional Protection: | No additional protection required. |
