2.1 Classification of the substance or mixture

HMIS® rating (product as packaged): Health: 1 Fire: 1 Reactivity: 2 PPE: B 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

D2A 3.2 Emergency overview and potential hazards This material is not hazardous under OSHA criteria.

Physical hazards

Under certain conditions this material may generate flammable hydrogen gas.

Potential Acute Health Effects

Route of entry or possible contact: eyes , skin , inhalation (volatile by-products) . Eye contact: May cause slight eye irritation. Skin contact: No acute toxic skin effects are expected. Inhalation: No acute toxic respiratory tract effects are expected. Inhalation is not expected due to low vapor pressure or high viscosity. Ingestion: Ingestion is not expected in industrial use. Additional information on acute health effects: The health hazard evaluation is based on test results and/or on known properties of ingredients. 3.3

Potential chronic health

Due to the physical nature of this material, there is no risk of inhalation exposure to ingredients presenting a respirable dust hazard. This includes any carcinogenic dusts which may be used as fillers or pigments (e.g., crystalline silica, carbon black or titanium dioxide). Impurity: Prolonged or repeated inhalation of vapors may have adverse effects on the reproductive system, based on animal testing of a component of this material. Medical conditions which may be aggravated by exposure: none known Target organs affected: Female Reproductive System. Signs and Symptoms of Exposure: Refer to Acute Health Effects, listed above. Carcinogens/Reproductive toxins: Based on animal tests. This material contains >= 0.1% of a substance which significantly increased the incidence of benign tumors in animal experiments. This material contains between 0.1% and 1% of a known reproductive toxin. Investigations of the mechanism of tumor formation are ongoing to evaluate the relevance to humans. Although animal testing has indicated that there is some limited carcinogenic potential for decamethylcyclopentasiloxane (D5) in rats, D5 has not been classified by IARC, NTP or OSHA as a known or potential human carcinogen. Further studies are ongoing to clarify the carcinogenic potential of D5 and the relevance to humans. See Section 11 for Toxicological Information, if any.
