SECTION 2 – Hazards Identification

Signal word: None required. The respirable crystalline silica content falls below the 0.1% threshold needed for a signal word.

GHS Hazard Pictogram: None. This material has been evaluated and does not require a pictogram.

GHS Hazard Statement: None. This material has been evaluated and does not present any GHS hazards.

Hazards Not Otherwise Classified (HNOC): Mechanical irritation only.

Supplemental information based on route of entry:

Skin contact: Repeated or prolonged contact may cause skin dryness as skin oils are absorbed.

Skin absorption: N/A

Eye contact: May irritate or injure eyes, mechanically.

Inhalation: Upper respiratory irritant. May aggravate pre-existing respiratory conditions. Long-term inhalation of respirable silica in excess of the PEL/TLV can cause disabling lung disease (silicosis).

Ingestion: LD50 not established, presumed over 10,000 mg/kg.

Sensitization: Non-sensitizing.

Emergency Overview: Coarse and fine particle size products represent inhalation hazards that can readily be controlled with appropriate dust protection equipment and techniques. Avoid processes that generate unnecessary dust.

Potential Health Effects: See above regarding long term exposure: skin irritation, silicosis and eye irritation.


SECTION 3 – Composition/Information on Ingredients

Product Description/Components: Expanded perlite powder or granules

Hazardous Ingredients: Respirable Quartz

Perlite ore: CAS 93763-70- 3; greater than 99.9%

SECTION 4 – First Aid Measures

Skin Contact: Wash off with soap and water. Skin lotion will quickly replace oils lost due to drying effect of perlite.

Eye Contact: Flush eyes with plenty of water holding the eye-lids apart. Do not rub eyes. Remove contact lenses if easy to do so. Continue rinsing. Get immediate medical attention.

Inhalation: Remove to fresh air. Get medical attention if victim is uncomfortable or not breathing. Ingestion: Do not induce vomiting. Rinse mouth.

Ingestion: Do not induce vomiting. Remove to fresh air. Drink water to clear throat and blow nose to evacuate dust.


SECTION 5 - Fire Fighting Measures

Flammable: No

Means of Extinction: Use extinguishing media appropriate for surrounding material that is on fire or could be set on fire.

HMIS Ratings: Health: *(See SDS), Flammability: 0, Reactivity: 0, Personal Protection: E


SECTION 6 - Accidental Release Measures

Leak and Spill Procedures: Spillage: Wear appropriate protective clothing. Collect using dustless method and place in appropriate container for use or disposal. Wetting spilled material with water may control dust and make clean up easier. Do not use compressed air. Report releases as required by local, state, provincial and federal authorities.

SECTION 7 - Handling and Storage

Handling Procedures and Equipment:
Avoid creating unnecessary dust. Wear protective clothing and equipment as described in Section 8. Use with adequate ventilation. Wash thoroughly with soap and water after handling. Keep containers closed when not in use.

Storage Requirements: Store with other dusty materials, away from products that could be affected by dust. Keep in original container until ready to use. Protect from physical damage. Store sealed in a cool, dry place.

SECTION 8 - Exposure Control/Personal Protection

Exposure Limits:

ACGIH TLV: 10 mg/m³ total dust, 3 mg/m³ respirable dust

OSHA PEL: 15 mg/m³ total dust, 5 mg/m³ respirable dust

LD50: 20,000 mg/kg

LC50: Not Available

Engineering Controls:
• General: Good housekeeping rules apply
• Local exhaust from work stations using this material
• Water spray to minimize dusting if appropriate
Recommended Personal Protective Equipment:
• Plastic or Rubber Gloves if skin dryness occurs
• Respirator – NIOSH/OSHA/MSHA approved dust respirator adequate for contaminant concentrations encountered.
• Eye protection recommended
• Disposable footwear for frequent handling of this material
• Coveralls for frequent handling of this material

Incompatibility with other substances? Yes. Hydrofluoric acid (HF) reactivity with silica. Toxic silicon tetrafluoride (SiF4) gas will result with contact with hydrofluoric acid. Do not use or mix this product with hydrofluoric acid!

Hazardous Decomposition Products: See above

SECTION 11 - Toxicological Information

Effects of Acute Exposure: Slightly hazardous in case of skin contact (irritant), of eye contact (irritant), or in case of inhalation (irritant).
Effects of Chronic Exposure: Irritancy of Product- Potential for creating skin dryness. Respiratory Irritation: Upper Respiratory Irritant: May aggravate pre-existing respiratory conditions.
Long-term inhalation of respirable crystalline silica can cause disabling lung disease (silicosis). For a comprehensive review, see: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC4002636/ Carcinogenicity: These products contain less than 1% crystalline silica, of which very low percentages (0.1 – 5.0%) are particles of respirable size. These products hence contain far lower than 0.1% respirable crystalline silica and present very low risk.

Potential Health Effects Summary

Dust may cause eye and upper respiratory irritation. Prolonged and repeated exposure to excessive concentrations can cause chronic pulmonary disease.

SECTION 12 – Ecological Information

Aquatic Toxicity: Generally considered chemically inert to the environment. If contaminated by liquid or semi-liquid the manner of disposal is governed by that liquid or semi-liquid. Consult the SDS of the contaminating product. Low hazard for usual industrial or commercial handling. Approved for use in soils.

SECTION 13 – Disposal Considerations Waste Disposal

The product as manufactured is suitable for landfill disposal. Used material which has become contaminated by liquid or semi-liquid will have significantly different characteristics based on the contaminants and should be evaluated accordingly. All materials should be disposed according to local, state, and federal laws.
