Section 3 - Hazards Identification








Potential Health Effects


Primary Entry Routes: Dermal

Acute Effects Inhalation: This is a viscous fluid that does not easily form a mist or vapor and, therefore,

inhalation hazards are minimal.

Eye:   Similar silicone fluids are non-irritating to eyes.  A slight transient irritation is possible.

Skin:  Similar silicone fluids are non-irritating to intact and abraded skin.

Ingestion: Animal tests for similar silicone fluids suggest very low acute oral toxicity.

Carcinogenicity: IARC, NTP, and OSHA do not list any components of this product as a carcinogen.

Medical Conditions Aggravated by Long-Term Exposure: No Data Found


Section 4 - First Aid Measures

Inhalation: Remove source(s) of contamination and move victim to fresh air.  Contact physician immediately. 

Eye Contact: Flush eyes with plenty of water. If irritation persists, seek medical attention.

Skin Contact: In case of skin contact, wash thoroughly with soap and water; remove contaminated clothing and launder before reuse; seek medical attention if rash develops.

Ingestion:  Do not induce vomiting unless instructed by a physician.   Contact physician immediately

After first aid, get appropriate in-plant, paramedic, or community medical support.





Section 5 - Fire-Fighting Measures

Flash Point: >300 °F

Flash Point Method: PMCC

LEL: Not Established

UEL: Not Established

Flammability Classification: Non-Flammable

Extinguishing Media: Dry Chemical, Carbon Dioxide, and Foam

Unusual Fire or Explosion Hazards: None

Fire-Fighting Instructions: Fire fighters should wear self-contained breathing apparatus.  Do not release runoff from fire control methods to sewers or waterways.

Fire-Fighting Equipment: Because fire may produce toxic thermal decomposition products, wear a self-contained breathing apparatus (SCBA) with a full face piece operated in pressure-demand or positive-pressure mode.


Section 6 - Accidental Release Measures

Spill /Leak Procedures: Dike and contain spill; absorb or scrape up excess into suitable container for disposal.  Stop or reduce discharge if it can be done safely.

Regulatory Requirements: Follow applicable OSHA regulations (29 CFR 1910.120).

Section 7 - Handling and Storage

Handling Precautions: Minimize breathing of vapors and avoid prolonged or repeated contact with skin.  Wear proper protective equipment.  Use good general housekeeping procedures.

Storage Requirements: Store in cool dry, well-ventilated area. 


Section 8 - Exposure Controls / Personal Protection

Engineering Controls:

Ventilation: Provide general or local exhaust ventilation systems to maintain airborne concentrations below OSHA PELs (Sec. 2). Local exhaust ventilation is preferred because it prevents contaminant dispersion into the work area by controlling it at its source.

Administrative Controls:

Protective Clothing/Equipment: Wear chemically protective gloves. Wear protective eyeglasses per OSHA eye and face protection regulations (29 CFR 1910.133). Contact lenses are not eye protective devices. Appropriate eye protection must be worn instead of, or in conjunction with contact lenses.

Comments: Never eat, drink, or smoke in work areas. Practice good personal hygiene after using this material, especially before eating, drinking, smoking, using the toilet, or applying cosmetics
