Administrative data
First-aid measures
Eye contact: IF IN EYES: Rinse cautiously with water for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing. Immediately call a POISON CENTER or doctor/physician.
Skin contact: Take off contaminated clothing and shoes immediately. Wash off immediately with plenty of water for at least 15 minutes. If skin irritation persists, call a physician.
Inhalation: Move to fresh air. Oxygen or artificial respiration if needed. Obtain medical attention.
Ingestion: Obtain medical attention. Do NOT induce vomiting. Never give anything by mouth to an unconscious person.
Notes to Physician: Material not fully tested. Pregnant or nursing women should avoid exposure.
Medical Surveillance: Employees who are pregnant, are breast-feeding, or who are concerned with other reproductive issues should be encouraged to consult with the occupational health physician monitoring worker's health.
Fire-fighting measures
Flammable Properties Nonflammable
Extinguishing Media Suitable extinguishing media: Dry chemical, Water spray, Foam
Unsuitable extinguishing media: Do NOT use water jet.
Protection of
Firefighters
Specific hazards: Not available
Protective equipment: Use personal protective equipment. In the event of fire, wear selfcontained
breathing apparatus.
Hazardous Combustion Products: carbon oxides (COx), oxides of phosphorus
Other information Avoid generating dust; fine dust dispersed in air in sufficient concentrations, and in the
presence of an ignition source is a potential dust explosion hazard. Decontaminate
protective clothing and equipment before reuse.
Accidental release measures
Personal precautions: Use personal protective equipment.
Examples include tightly fitting safety goggles, lab coat and impervious gloves. Wear
respiratory protection. Depending on the nature of the spill (quantity and extent of spill)
additional protective clothing and equipment such as a self-contained breathing apparatus
may be needed.
Environmental
precautions
Prevent release to drains and waterways. Prevent release to the environment.
Containment Methods Wet down any dust to prevent generation of aerosols, if appropriate. Cover with suitable
material.
Cleanup Methods Contain and collect spillage and place in container for disposal according to local
regulations. Use a HEPA vacuum or moisten materials to minimize dust
generation during pick-up. Clean area with detergent and water after spill pick-up, if
appropriate. Handle waste materials, including gloves, protective clothing, contaminated
spill cleanup material, etc., as appropriate for chemically and pharmacologically similar
materials.
Other information Dust deposits should not be allowed to accumulate on surfaces, as these may form an
explosive mixture if they are released into the atmosphere in sufficient concentration.
Avoid dispersal of dust in the air (i.e., clearing dust surfaces with compressed air).
Nonsparking tools should be used.
Handling and storage
Handling Precautions Avoid exposure - obtain special instructions before use. Avoid formation of dust and
aerosols. Keep away from heat and sources of ignition. Minimize dust generation and
accumulation. Routine housekeeping should be instituted to ensure that dusts do not
accumulate on surfaces. Dry powders can build static electricity charges when subjected to
the friction of transfer and mixing operations. Provide adequate precautions, such as
electrical grounding and bonding, or inert atmospheres. Refer also to Section 10. Prevent
release to drains and waterways.
Container
Requirements
Store in sturdy containers appropriate to maintain the integrity of this material for its
intended use. Keep container tightly closed.
Storage Conditions Store at room temperature. Keep away from heat, sparks and flames. Avoid moisture.

Exposure controls / personal protection
Engineering Controls and Ventilation
Use process enclosures, containment technology, or other engineering controls to keep
airborne levels below recommended exposure limit. When handling quantities up to 15
milligrams, a standard laboratory with general laboratory dilution ventilation (e.g. 6-12 air
changes per hour) is appropriate. When handling quantities from 15 milligrams to 1 kilogram,
work in a standard laboratory using a fume hood, biological safety cabinet(Class II, all types),
or approved vented enclosure. Quantities exceeding 1 kilogram should be handled in a
designated laboratory. A laminar flow/powder containment booth is recommended for
handling >1 kilograms of active substance. For manufacturing and pilot plant operations, use
direct coupling and closed transfer systems for all bulk transfers. Use dust tight valves as
appropriate. HEPA filtration of local exhaust ventilation (LEV) is required.
It is recommended that all dust control equipment such as local exhaust ventilation and
material transport systems involved in handling of this product contain explosion relief vents
or an explosion suppression system or an oxygen deficient environment. Ensure that dusthandling
systems (such as exhaust ducts, dust collectors, vessels, and processing equipment)
are designed in an manner to prevent the escape of dust into the work area (i.e., there is no
leakage from the equipment). Use only appropriately classified electrical equipment and
powered industrial trucks.
Respiratory protection
Use and selection of respiratory protection is based upon engineering controls in use and
potential for aerosol generation. When engineering controls are not sufficient control
exposure, wear an approved respirator with NIOSH Class 100 or high efficiency particulate
(HEPA) filters or cartridges (EN 140/EN 136) when exposures are up to 10 times the exposure
control guideline. Wear a loose-fitting (Tyvek or helmet type) HEPA powered-air purifying
respirator (PAPR) (EN 12941) when exposures are 10-25 times the exposure control
guideline. Wear a full facepiece negative pressure respirator with Class 100 or HEPA filters
(EN 136) when exposures are 25-50 times the exposure control guideline. Wear a tightfitting,
full facepiece HEPA PAPR (EN 12942) when exposures are 50-100 times the exposure
control guideline. Wear a hood-shroud HEPA PAPR (EN 12941) or full facepiece supplied
air respirator (EN 139) operated in a pressure demand or other positive pressure mode when
exposures are 100-1000 times the exposure control guideline.
Eye protection Safety glasses with side-shields are recommended (EN 166). Face shields or chemical safety
goggles (EN 166) may be required if splash potential exists or if corrosive materials are
present. Note: Choice of eye protection may be influenced by the type of respirator which is
selected.
Hand protection
Impervious nitrile, rubber and latex gloves are recommended (EN 420, EN 374). If material
is handled in solution, the solvent should also be considered when selecting protective clothing
material. Please note that employees who are allergic to natural rubber latex should use nitrile
gloves.
Skin and body protection
Wear a laboratory coat (EN 340) when handling quantities up to 1 kilogram. For quantities
over 1 kilogram, wear laboratory coat(EN 340)or coverall of low permeability (EN 1149-1).
For manufacturing operations, wear coverall of low permeability (EN 465/1149-1). For
manufacturing operations, wear coverall of low permeability (EN 1149-1).
Hygiene Wash hands and face before breaks and immediately after handling the product.
