mg/m3 for total dust. The OSHA PEL for respirable dust is 5.0 mg/m3 and 15.0 mg/m3 for total dust.
Irritancy of product: dust may produce mechanical irritation to the mucous membranes of the eyes, nose, throat and upper
respiratory tract. Causes eye irritation. Causes skin irritation.

conditions of temperature and pressure
Product incompatible with: No data available
Conditions of reactivity: No data available.
Conditions to avoid: No data available.
Hazardous decomposition products: No data available.
SECTION VIII: PREVENTATIVE MEASURES
Personal protective equipment:
Eye/Face Protection: Wear eye protection such as safety glasses, chemical goggles, or face shields if engineering controls or work
practices are not adequate to prevent eye contact.
Skin Protection: Wear impervious protective clothing to prevent skin contact. Selection of protective clothing may include gloves,
apron, boots, and complete facial protection depending on operations conducted. Users should determine acceptable performance
characteristics of protective clothing. Consider physical requirements and other substances present when selecting protective
clothing. Suggested materials for protective gloves include: Nitrile
Respiratory Protection: If user operations generate harmful levels of airborne material that is not adequately controlled by
ventilation, wear a NIOSH approved respirator that provides adequate protection. Use the following elements for air-purifying
respirators: Air-Purifying Respirator for Particulates (HEPA)
Specific engineering controls: If heated material generates vapor or fumes, use process enclosures, local exhaust ventilation, or
other engineering controls to control exposure.
Procedures for leak/spills: Use appropriate safety equipment. Sweep up, and collect, uncontaminated material for repackaging.
Sweep up, and collect contaminated material for disposal. Avoid excessive production of dust.
Waste disposal: Use material for its intended purpose or recycle if possible. This material, if it must be discarded, may meet the
criteria of a hazardous waste as defined by local regulations. Measurement of certain physical properties and analysis for
regulated components may be necessary to make a correct determination. If this material is classified as a hazardous waste, the
law requires disposal at a licensed hazardous waste disposal facility. Dispose according to local ordinances.
Handling procedures and equipment: Use caution to avoid creation of dusts and to prevent inhalation of product dust (fines).
Avoid contact with product dust. Airborne dust concentrations above 20 mg/L may create a dust explosion hazard. Avoid
breathing vapors or fumes which may be released during thermal processing. Do not breathe dust at levels above the
recommended exposure limits. Avoid breathing material. Keep container closed. Use only with adequate ventilation. Avoid
contact with eyes, skin and clothing. Discard contaminated clothing and shoes or thoroughly clean before reuse. Do not get in
eyes. Do not taste or swallow. Do not breathe dust.
Static Hazard: Electrostatic charge may accumulate and create a hazardous condition when handling this material. To minimize
this hazard, bonding and grounding may be necessary but may not, by themselves, be sufficient. Review all operations, which
have the potential of generating an accumulation of electrostatic charge and/or a flammable atmosphere (including tank and
container filling, splash filling, tank cleaning, sampling, gauging, switch loading, filtering, mixing, agitation, and vacuum truck
operations) and use appropriate mitigating procedures. For more information, refer to OSHA Standard 29 CFR 1910.106,

Against Ignitions Arising Out of Static, Lightning, and Stray Currents' (liquids).
Storage requirements: Treat as a solid that can burn. Store away from oxidizing materials, in a cool, dry place with adequate
ventilation. Bond and ground transfer equipment. DO NOT USE OR STORE near heat, sparks or open flames. USE AN STORE ONLY IN WELL VENTILATED AREA. Keep container closed when not in use.
Container Warnings: Container is not designed to contain pressure. Do not use pressure to empty container or it may rupture
with explosive force. Empty containers retain product residue (solid, liquid, and/or vapor) and can be dangerous. Do not
pressurize, cut, weld, braze, solder, drill, grind, or expose such containers to heat, flame, sparks, static electricity, or other sources
of ignition. They may explode and cause injury or death. Empty containers should be completely drained, properly closed, and
promptly returned to a drum reconditioner or disposed of properly. Containers, even those that have been emptied, can contain
residues of dusts or solid particulates which may create both health and fire/explosion hazards
