Emergency overview:
Supplied in thin sheets, or cut discs. Not considered hazardous.
The materials can be cleaved ("micaceous cleavage") to expose freshly
cleaved surface, a procedure that is generally not expected to generate
a particulates hazard. If the material is cut with a scissors, or scored
with a diamond scribe, then it could be expected that particulates would
be generated.
Potential Health Hazards:
Skin:
Not considered hazardous, though dust, if generate could be irritating.
Eyes:
Not considered hazardous. May cause mechanical irritation if particles
are generated and they should get into the eye.
Inhalation:
Not a route of exposure under normal usage, unless the materials is
excessively cut or even ground, to generate dust particles. May be
harmful if inhaled over a long period of time and may also cause
delayed lung injury. Always avoid breathing dust of this material.
Ingestion:
Not a route of exposure. Not considered hazardous.
Delayed Effects:
None known.
Conditions Aggravated by Exposure:
No known conditions are aggravated by this material.
Effects of Over Exposure:
Shortness of breath or dry cough are the first symptoms. If such
symptoms occur, remove to fresh air and contact physician.
Carcinogenicity:
Mica is not listed as a carcinogen or potential carcinogen by the
National Toxicology Program of the U. S. Public Health Service, nor
has it been found to be a carcinogen or potential carcinogen by OSHA
or the Int'l Agency for Research on Cancer. Many commerical micas are
contaminated with respirable free silica (quartz) but the high purity
mica supplied by SPI Supplies, especially if used as intended will not
liberate any such silica, even at low levels.
Ingredients found on one of the OSHA designated carcinogen
lists are listed below.
INGREDIENT NAME NTP STATUS IARC STATUS OSHA LIST
None found
Take proper precautions to ensure your own health and safety before attempting
to rescue and providing first aid. For specific information refer to the
Emergency Overview in Section of this MSDS.
Skin:
Not hazardous if used as microscopy substrate materials. If particulates
are being generated and the skin is contaminated, wash thoroughly with soap
and water.
Eyes:
None needed under normal usage. If material comes into contact
with the eye, flush eyes with water while holding eyelids apart
to ensure complete irrigation. When cleaving, always wear safety
glasses.
Inhalation:
None needed under normal usage. If particulates are being generated,
then victim should be at once removed to fresh air and if respiratory
distress continues, a physician contacted.
Ingestion:
None needed.
Advice to physician:
None.
Flammable Properties
Flash Point: Non-flammable, Non explosive
Flash Point Method: Not applicable.
Autoignition Temperature: Not determined.
Upper flame limit (volume % in air):
Not applicable. Non-volatile solid. Lower flame limit
(volume % in air): Not applicable. Non-volatile solid.
Flame propagation rate (solids):
Not determined.
OSHA Flammability class:
Not determined.
Extinguishing Media:
Not applicable
Unusual Fire and Explosion Hazards:
None known
Special Fire Fighting Precautions/Instructions:
None
In Case of Spill or Other Release: (Always wear recommended personal protective equipment.) Collect and place in a solid waste container. Material is not dangerous if spilled. Wash away with water or vacuum with high efficiency HEPA filter. Powder or flakes of the material could become slippery and constitute a "slip and fall" hazard.
Normal Handling: (Always wear recommended personal protective equipment.) Use normal personal hygiene and good housekeeping. Storage Recommendations: No special recommendations. However, to extend the shelf life of the products, we would recommend that material be stored in dry environment.
Engineering Controls:
None needed if material is used as it was intended to be used,
that is, as a substrate for microscopy research and testing.
Personal Protective Equipment:
Safety glasses if cleaving or cutting operations are anticipated.
Skin Protection:
Not normally required unless cutting or grinding is contemplated.
Eye Protection:
As a general practice in manufacturing areas, safety glasses that
conform to ANSI Z87.1 should be worn.
Respiratory Protection:
Under normal usage, not normally required. A NIOSH/MSHA approved
respirator should be worn in areas where the PEL/TLV is exceeded.
Additional Recommendations:
None.

Will not occur.
Hazardous Polymerization:
Will not occur.
Immediate (Acute) Effects:
Not determined.
Delayed (Subchronic and Chronic) Effects:
None known.
Other Data:
None.
Exotoxicity:
Exotoxicity is expected to be low based on the zero water
solubility of the material. Material is considered inert and
not expected to be biodegradable or toxic.
Bioaccumulation:
Not expected to occur.
RCRA
Is the unused product a RCRA hazardous waste if discarded? No.
Other Disposal Considerations:
Dispose of in compliance with Federal, state and local government
regulations. Usually considered an inert packaging material that
can be recycled or landfilled.
The information offered here is for the product as shipped. Use and/or
alterations to the product such as mixing with other materials may
significantly change the characteristics of the material and alter the
RCRA classification and the proper disposal method.
US DOT Hazard Class: Not regulated. US DOT ID Number: Not applicable, none assigned.
Toxic Substances Control Act (TSCA) TSCA Inventory Status: Listed on the TSCA Inventory. Other TSCA Issues: None. SARA TITLE III/CERCLA "Reportable Quantities" (RQs) and/or "Threshold Planning Quantities" (TPQs) exist for the following ingredients. INGREDIENT NAME SARA/CERCLA RQ (lb) SARA EHS TPQ (lb) No ingredients listed in this section. Spills resulting in the loss of any ingredient at or above its RQ requires immediate notification to the National Response Center (1-800-424-8802) and to your Local Emergency Planning Committee.
