| |
Health effects described above are based on published scientific information available for review, and evaluated on behalf of this product. Actual signs and symptoms experienced may vary due to conditions at the time of exposure. |
| After Inhalation |
Remove to fresh air. If conscious, have victim clear nasal passages. Restore breathing (e.g., artificial respiration, CPR). Seek medical attention, as necessary, if symptoms develop or persist. |
| After Skin Contact |
In case of contact, wipe off excess material from skin then immediately flush skin with plenty of water for at least 15 minutes. Wash clothing before reuse. Call a physician, if irritation occurs. |
| After Eye Contact |
Holding eyelids open, do not allow victim to rub their eyes. Gently flush eyes for 15 minutes with large quantities of water. Seek medical attention if irritation develops or persists. |
| After Ingestion |
Never give anything by mouth to an unconscious person. Get medical aid immediately. Do NOT induce vomiting. If conscious and alert, rinse mouth and drink 2 to 4 cupfuls of milk or water. |

| Spill Procedures |
Protect against identified hazards through use of prescribed personal protection equipment, proper work and hygiene practices. Limit foot and vehicular traffic to minimize mechanical agitation and dispersion. Employ a vacuum, equipped with HEPA (High Efficiency Particulate Air) filter, for clean-up of the spill material. If no vacuum is available, use a broom and shovel to collect excess powder in the area. Residual material should then be cleared, utilizing the process of wet sweeping, to avoid dust generation. |
| Containment Techniques |
This is a solid material and will not travel far from the spill location unless mechanically agitated. Therefore, no specific containment techniques are recommended outside of restricting access to the spill location. During spill cleanup, residual wash waters should be contained and collected for proper disposal. |
| Spill Response Equipment |
The following equipment is recommended for spill response:
• vacuum, equipped with a HEPA filter
• broom, wet mop
• dustpan, shovel, or scoop
• bags, drums, or sacks for collection
Note: Non-sparking equipment may be selected, based on location specific requirements and individual work site evaluations. |
| Personal Protective Equipment |
Employees should utilize the following protective equipment when performing spill response activities:
• gloves (rubber or leather)
• cotton or Tyvek coveralls
• chemical/safety impact goggles
• respiratory equipment recommended in Section 8 |
| Handling |
When handling this product, all personnel are directed to:
• Wear all specified elements of PPE, as directed by this document, or under location specific requirements, whichever is more conservative.
• Avoid creating dust, where possible. |
| Storage |
The following information provides the appropriate and recommended methods for safe storage and maintenance of product integrity:
• Store in a cool, dry, well-ventilated area.
• Product containers (paper bags, nylon bags, drums, etc.) are prone to physical damage. Care should be taken in storage and handling in order to prevent damage.
• Avoid contact with oxidizers and chemically active metals, since violent reactions may occur. |
| Engineering Controls |
If user operations generate dusts or fumes, use process enclosures, local exhaust ventilation, or other engineering controls to keep airborne levels below recommended exposure limits. |
| Respiratory Protection |
If the exposure limit is exceeded and engineering controls are not feasible, a full facepiece particulate respirator (NIOSH type N100 filters) may be worn for up to 50 times the exposure limit or the maximum use concentration specified by the appropriate regulatory agency or respirator supplier, whichever is lowest. If oil particles (e.g. lubricants, cutting fluids. glycerine, etc.) are present, use a NIOSH type R or P filter. For emergencies or instances where the exposure levels are not known, use a full-facepiece positive-pressure, air-supplied respirator. WARNING: Air-purifying respirators do not protect workers in oxygen-deficient atmospheres. |
| Skin Protection |
Wear impervious protective clothing, including boots, gloves, lab coat, apron or coveralls, as appropriate, to prevent skin contact. |
| Eye/Face Protection |
Use chemical safety goggles and/or full face shield where dusting or splashing of solutions is possible. Maintain eye wash fountain and quick-drench facilities in work area. |
| Work Hygiene Practices |
To control potential exposures, avoid creating dust. Always wear appropriate protective equipment when handling. To avoid skin contact, gloves (leather or rubber) should be worn when handling containers of this substance. Do not eat, drink, smoke or apply cosmetics while using/handling. Always wash hands and face after handling.
• Avoid direct skin contact when possible.
• Do not eat, drink, smoke, or perform other hand-to-mouth activities in product use or handling area.
• Wash thoroughly after handling this product. |
