| Extinguishing Media | This material is not combustible and is not anticipated to react with commercially employed extinguishing media. Use appropriate extinguishing media for surrounding fire. |
| Special Fire Fighting Procedure | As part of responding to any fire, firefighters should wear full turnout gear with a positive pressure demand mode Self-Contained Breathing Apparatus (SCBA). Contain all fire suppression run-off. |
Hazardous Thermal
Decomposition Byproducts | These are carbon oxides (CO, CO2) and nitrogen oxides (NO, NO2...). |
| Fire/Explosion Hazards | No information available |
|
| 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 | Dust respirator. Be sure to use an approved/certified respirator or equivalent. |
| Skin Protection | Wear impervious protective clothing, including gloves, lab coat, apron or coveralls, as appropriate, to prevent skin contact. |
| Eye/Face Protection | Use chemical safety goggles where dusting 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. |
