| 3.) HAZARDS IDENTIFICATION | |
| Emergency Overview: | Follow safe industrial hygiene practices and always wear protective equipment when handling this compound. |
| Potential Health Effects: | Irritating to the skin and eyes on contact. Inhalation will cause irritation to the lungs and mucous membrane. Irritation to the eyes will cause watering and redness. Reddening, scaling, and itching are characteristics of skin contact. |
|
|
| 4.) FIRST AID MEASURES | |
| Inhalation: | Remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Call a physician. |
| Skin Contact: | Flush skin with water. Wash clothing before reuse. Call a doctor if irritation occurs. |
| Eye Contact: | Immediately flush eyes with plenty of water for at least 15 minutes. Call a doctor. |
| Ingestion Contact: | If swallowed, call a physician immediately. |
|
|
| 5.) FIRE FIGHTING MEASURES | |
| Extinguishing Media: | Class D Fire: Use dry powder, dry sand or CO2 to smother fire. |
| Special Fire Fighting Procedures: | Fire may also be isolated and allowed to burn itself out. Do not disturb burning metal while extinguishing the fire. |
| Fire and Explosion Hazzards: | Lump material is not combustible. When suspended in air, dusts of silicon metal can be readily ignited, propagate flame, and generate some pressure or explode. The degree of combustibility in air is dependent upon particle size, oxide coating, and quality of dispersion. The hazard increases with particle fineness |
| Hazardous Combustion Products: | No information found. |
| Protective Measure in Fire: | Avoid generating sparks or ignition sources in areas of high airborne dust levels or in areas with accumulated dust. Thoroughly clean areas or equipment to be maintained prior to dust disturbing or ignition source generation activities. |
|
|
| 6.) ACCIDENTAL RELEASE MEASURES | |
| Personal Precaution in Spill: | Utilize recommended protective clothing and equipment. |
| Environment: | Collect wash water for approved disposal. Keep from entering water or ground water. |
| Spill Clean Up: | Clean spills in a manner that does not disperse dust into the air. Spill area can be washed with water. |
|
|
| 7.) HANDLING/STORAGE | |
| Usage Precautions: | |
| Usage Descriptions: | |
| Storage Precautions: | |
| Handling Precautions: | Store at ambient temperature. Avoid breathing dust. Avoid getting in eyes or on skin. Wash thoroughly after handling. Store in a dry place away from direct sunlight, heat and incompatible materials. Reseal containers immediately after use. Store away from food and beverages. |
|
|
| 8.) EXPOSURE CONTROLS / PERSONAL PROTECTION | |
| Protective Equipment: | Use local ventilation if dusting is a problem, to maintain air levels below the recommended exposure limit. |
| Process Conditions: | OSHA TLV: 15 mg/m3 |
| Respirators: | Work ambient concentrations should be monitored and if the recommended exposure limit is exceeded, a NIOSH/MSHA approved dust respirator must be worn. |
| Protective Gloves: | Wear PVC gloves. |
| Eye Protection: | Wear safety glasses or goggles. Emergency showers and eye wash stations should be available. |
| Other Protection: | Wear impervious boots and apron or coveralls. |
| Hygienic Work Practices: | Educate and train employees in the safe use and handling of hazardous chemicals. Employees should wash their hands and face before eating, drinking or using tobacco products. |
