Potential Health Effects:
There is insufficient data in the published literature to perform a complete
hazard evaluation for this product. Special precautions must be used in
storage, use and handling. Protective equipment should be chosen using
Mild irritant. Symptoms may include coughing on sneezing. May cause
irritation to the respiratory tract.
Substance has low toxicity by ingestion. Large amount may cause gastric
upset due to osmotic imbalance through the sequestering of metal ions.
Mild irritant. Symptoms may include reddening or inflammation on
Causes irritation. Solutions are severe irritants to the eye and cause pain,

Aggravation of Pre-existing Conditions:
No information found.
- First Aid Measures
If inhaled, remove to fresh air. If not, breathing, give artificial respiration. If
breathing is difficult, give oxygen. Call a physician.
Remove any contaminated clothing. Wash skin with soap or mild detergent
and water for at least 15 minutes. Get medical attention if irritation
develops or persists. Wash clothing before re-use.
Immediately flush eyes with plenty of water for at least 15 minutes. Lifting
lower and upper eyelids occasionally. Get medical attention immediately.
- Fire Fighting Measures
Not considered to be a fire hazard.
Not considered to be an explosion hazard.
Fire Extinguishing Media:
Use any means suitable for extinguishing surrounding fire.
In the event of a fire, wear full protective clothing and NIOSH-approved
self-contained breathing apparatus with full-face piece operated in the
pressure demand or other positive pressure mode.
- Accidental Release Measures
Ventilate area of leak or spill. Wear appropriate personal protective
equipment as specified in Section 8. Spills: Pick up and place in a suitable
container for reclamation or disposal, using a method that does not
- Handling and Storage
Keep in a tightly closed container, stored in a cool, dry, ventilated area.
Protect against physical damage. Containers of this material may be
hazardous when empty since they retain product residues (dust, solids);
observe all warnings and precautions listed for the product.
8.Exposure Control/Personal Protection
Airborne Exposure Limits.
-OSHA Permissible Exposure Limit (PEL);
15mg/m3 total dust, 5mg/m3 respirable fraction for nuisance dust;
-ACGITI Threshold Limit Value (TLV);
10mg/m3 total dust containing no asbestos and <1% crystalline silica for
Particulates Not Otherwise Classified (PNOC).
A system of local and/or general exhaust is recommended to keep
employee exposures below the Airborne Exposure Limits. Local exhaust
ventilation is generally pretaned because it can control the emissions of the
contaminant at its source, preventing dispersion of it into the general work
area. Please refer to the ACGIH document. Industrial Ventilation, A Manual
of Recommended Practices, most recent edition for details.
Personal Respirators (NIOSH Approved)
If the exposure limit is exceeded and engineering controls are not feasible,
a half face-piece particulate respirator (NIOSH type N95 or better filter) may
be worn for up to ten times the exposure limit or the maximum use
concentration specified by the appropriate regulatory agency or respirator
supplier, whichever is lowest. A full-face piece particulate respirator (NIOSH
type N100 filters) may be worn up to 50 times the exposure limit, or the
maximum use concentration specified consignments of instances where the
exposure levels are not known, use a full-face piece positive-pressure,
air-supplied respirator. WARNING: Air-purifying respirators do not protect
workers in oxygen-deficient atmospheres.
Wear protective gloves and clean body-covering clothing.
Use chemical safely goggles. Maintain eye wash fountain and quick-drench
facilities in work area.
