SECTION 2: Hazards identification
3.1
2.1 Classification of the substance or mixture
HMIS® rating (product as packaged): Health: 1 Fire: 0 Reactivity: 0 PPE: E Note: Respiratory protection is only recommended in the event that ventilation or engineering controls are unable to maintain exposures below recommended levels; or in the event of a spill or other emergency response situation. Hazardous Materials Identification System and HMIS are registered trademarks of the National Paint and Coatings Association. (HMIS codes are based on contact with the product as packaged and any hydrolysis by-products, if present.)
WHMIS Classification
None 3.2 Emergency overview and potential hazards
Physical hazards
Nuisance dust.
Potential Acute Health Effects
Route of entry or possible contact: eyes , skin , inhalation Eye contact: No acute toxic effects are expected. Slight irritation by mechanical effects is possible. Skin contact: No acute toxic effects are expected. Temporary discomfort like feeling of dryness on the skin. Inhalation: No acute toxic effects are expected. May cause physical discomfort to the respiratory tract. Ingestion: Not expected in industrial use. Additional information on acute health effects: Re Sect. 11.2 "Toxicological data", LC50 (inhalative): no mortalities at highest technical achievable concentration (rat) . 3.3
Potential chronic health
Toxicological test results with a similar hydrophobic amorphous silica: A long term exposure exceeding TLV can lead to damaging effect as a result of mechanical overloading of the respiratory tract. Chronic respiratory exposure: Changes in respiratory organs observed in animal experiments (inflammatory processes) were reversible; no indication of silicosis. Animal tests have shown no indication to carcinogenic or to reproduction effects. Medical conditions which may be aggravated by exposure: unknown Carcinogens/Reproductive toxins: This material does not contain any reportable carcinogenic ingredients. This material does not contain any reproductive toxins at or above OSHA or WHMIS reportable levels. See Section 11 for Toxicological Information, if any.
