| SECTION 3: Hazards Identification | |
|---|---|
| Emergency Overview: | Material hydrolyzes in contact with moisture releasing corrosive hydrogen bromide fumes. Harmful by inhalation, in contact with skin and if swallowed. |
| Primary Routes of Exposure: | Ingestion, inhalation, skin, eyes |
| Eye Contact: | Liquid and vapors will cause burns to the eyes. May cause blindness. |
| Skin Contact: | Corrosive to skin. Contact can lead to redness, pain, blistering, ulceration, and scar formation. |
| Inhalation: | Inhalation of choking fumes will result in chemical burns of the respiratory tract, chemical pneumonitis and pulmonary edema. |
| Ingestion: | Causes burns to the gastrointestinal system. Selenium compounds may lead to nausea, vomiting, and bloody diarrhea. |
| Acute Health Effects: | Material is extremely destructive to all body tissues. Selenium compounds cause nausea, vomiting, bloody diarrhea, weakness, chills, headache, and delayed pulmonary edema. |
| Chronic Health Effects: | Prolonged exposure to selenium compounds may cause dermatitis, diarrhea, liver damage, nervous disorders, lameness, and loss of vitality. |
| 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 bromide 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 mixed with powdered sodium bicarbonate, lime, or calcium carbonate and swept up. Spillage in areas not adequately ventilated may require an evacuation of area. 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. 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 clothing and gloves. Consult with glove manufacturer to determine 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: | Protective work clothing. |
