Section 3 - Hazards Identification
EMERGENCY OVERVIEW |
| Harmful if swallowed. Causes burns. May cause sensitization by inhalation and skin contact. |
| Potential Health Effects |
| Eye: |
Causes eye burns. May cause conjunctivitis. Causes redness and pain. |
| Skin: |
Causes skin burns. May cause skin sensitization, an allergic reaction, which becomes evident upon re-exposure to this material. Causes redness and pain. May cause blistering of the skin. |
| Ingestion: |
Harmful if swallowed. Causes gastrointestinal tract burns. |
| Inhalation: |
May cause allergic respiratory reaction. May cause irritation of the respiratory tract with burning pain in the nose and throat, coughing, wheezing, shortness of breath and pulmonary edema. Causes chemical burns to the respiratory tract. |
| Chronic: |
Repeated exposure may cause allergic respiratory reaction (asthma). Prolonged or repeated contact may cause possible eczema. |
| Section 4 - First Aid Measures |
| Eyes: |
Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid immediately. |
| Skin: |
Get medical aid immediately. Immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes. |
| Ingestion: |
Get medical aid immediately. Wash mouth out with water. |
| Inhalation: |
Get medical aid immediately. Remove from exposure and move to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. |
| Notes to Physician: |
Treat symptomatically and supportively. |
| Section 5 - Fire Fighting Measures |
| General Information: |
As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Dusts at sufficient concentrations can form explosive mixtures with air. |
| Extinguishing Media: |
Use water spray or carbon dioxide. Do not use dry chemical powder extinguisher because they contain carbonates which react with product. |
| Section 6 - Accidental Release Measures |
| General Information: |
Use proper personal protective equipment as indicated in Section 8. |
| Spills/Leaks: |
Vacuum or sweep up material and place into a suitable disposal container. Do not let this chemical enter the environment. |
| Section 7 - Handling and Storage |
| Handling: |
Avoid breathing dust, vapor, mist, or gas. Avoid contact with skin and eyes. Take precautionary measures against static discharges. |
| Storage: |
Store in a cool, dry place. Store in a tightly closed container. Store protected from moisture. |
| Section 8 - Exposure Controls, Personal Protection |
| Engineering Controls: |
Facilities storing or utilizing this material should be equipped with an eyewash facility and a safety shower. Use adequate ventilation to keep airborne concentrations low. |
