11. Toxicological Information
Acute Inhalation Effects:
Eye contact may cause irritation and skin contact may cause irritation or erythema, which are considered to
be transient disease, not chronic one.
Chronic Effects:
Prolonged and excessive inhalation of fiber may cause respiratory disease because generated dust contains
inhalable fiber. At this time there are no known published reports demonstrating negative health outcomes ofworkers exposed to this product.
Carcinogenicity:
CMS wools have been tested for their biopersistence using methods devised by the European Union.
The results from these studies exonerate CMS wools from carcinogen classification under criteria listed inNota Q of European Commission Directive 97/69/EU.
In a lifetime carcinogenicity test, rats were exposed by inhalation for two years (5 days a week; 6 hours a day)to CMS fibers at 200WHO fibers/ml. There was neither fibrosis nor carcinogenic response; only reversible
cellular changes were seen. Further, subchronic inhalation studies on rats with CMS fibers at concentrationsof 150 fibers (>20 micron long) per ml for 90 days with follow up to 1 year showed neither inflammation norcell proliferation. All parameters studied returned rapidly to baseline levels on cessation of exposure.
After-service, CMS wools may contain crystalline phases including some forms of silica. (See Section 16)
However, CMS fibers heated to 1000 degrees C for 2 weeks were not cytotoxic to macrophage-like cells at

concentrations up to 320 microgram/cm2. In the same test, samples of pure crystalline quartz weresignificantly active at 20 microgram/cm2.
Mutagenicity: None

regulatory agency.

EUROPEAN UNION
This product is exonerated from any carcinogenic classification in the countries of the European Union underthe provisions of Nota Q of the European Commission Directive 97/69/EC.

16. Other Information
This products are vitreous (glassy) AES Wools that do not contain crystalline silica. Continued exposure toevated temperatures (>900 degrees C) may cause these materials to form crystalline phases, including
crystalline silica. The occurrence and extent of crystalline silica formation is dependent on the duration andtemperature of exposure, CMS Wool chemistry and /or the presence of fluxing agents. The presence ofcrystalline silica can be confirmed only through laboratory analysis of the “hot face” fiber. If crystalline silica ispresent, follow appropriate hygiene standards and national regulations.
Devitrified, after-service this products, containing crystalline silica, has shown no adverse reactions in toxicity
assays (See Section 11). These findings are consistent with IARC’s evaluation, which states “Crystalline silica
inhaled in the form of quartz or cristobalite from occupational sources is carcinogenic to humans (Group 1)” andFT-SDS-E184-a
1st Ed.: Oct. 16th, 2017
2nd Ed.: Jul. 23rd, 2021
additionally notes “carcinogenicity in humans was not detected in all industrial circumstances studied.
Carcinogenicity may be dependent on inherent characteristics of the crystalline silica or on external factors
affecting its biological activity or distribution of its polymorphs.” (IARC Monograph Vol. 68, 1997)
Respirable dust from devitrified this products can be controlled with ventilation, dust collectors or personal
protective equipment as detailed in Section 8 (above).
