Potential Health Effects

 

Primary Entry Routes: Inhalation and Dermal

Acute Effects Inhalation: This product has not been tested.  However, inhalation studies of ethyl silicate in a rat gave a LCLo of 1000ppm/4h and in a guinea pig a LCLo of 700 ppm/6h.

Eye: May cause irritation, redness, tearing, and blur vision.  Prolonged vapor contact may cause conjunctivitis.

Skin:  Contact may cause irritation, reddening, and possible rash. 

Ingestion: This product has not been tested but should be considered Toxic By Mouth based on the organotin compound’s acute oral/rat LD50: 175 mg/Kg.

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 Available

 

Section 4 - First Aid Measures

Inhalation Remove source(s) of contamination and move victim to fresh air.  If breathing has stopped, give artificial respiration, then oxygen if needed.  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:  110°F (43.3°C)                LEL: Not Established                       UEL: Not Established

Flash Point Method: PMCC

Flammability Classification: Combustible Liquid

Extinguishing Media: Dry Chemical, Carbon Dioxide, and Foam

Unusual Fire or Explosion Hazards: On combustion, silica, tin oxide and carbon dioxide are emitted.

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 facepiece operated in pressure-demand or positive-pressure mode.


 

Section 6 - Accidental Release Measures

Spill /Leak Procedures: Evacuate area.  Eliminate all sources of ignition.  Put on appropriate protective gear including NIOSH/MSHA approved self-contained breathing apparatus, rubber boots and heavy rubber gloves.  Absorb on vermiculite Place in covered containers using non-sparking tools and transport outdoors. Ventilate area and wash spill site after material pickup is complete.

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.  If ventilation is not sufficient, wear proper respiratory equipment. Reseal partial containers.  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:

Respiratory Protection: Seek professional advice prior to respirator selection and use. Follow OSHA respirator regulations (29 CFR 1910.134) and, if necessary, wear an MSHA/NIOSH-approved respirator. Select respirator based on its suitability to provide adequate worker protection for given working conditions, level of airborne contamination, and presence of sufficient oxygen. For emergency or nonroutine operations (cleaning spills, reactor vessels, or storage tanks), wear an SCBA. Warning! Air-purifying respirators do not protect workers in oxygen-deficient atmospheres. If respirators are used, OSHA requires a written respiratory protection program that includes at least: medical certification, training, fit testing, periodic environmental monitoring, maintenance, inspection, cleaning, and convenient, sanitary storage areas.

Protective Clothing/Equipment: Wear chemically protective gloves, boots, and aprons to prevent prolonged or repeated skin contact. Wear protective eyeglasses or chemical safety goggles, 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
