The ACGIH2, OSHA, and Canadian provinces exposure limits were consulted. Limits from by RTECS database1 of the Canadian Centre for Occupational Health and Safety (CCOHS) a data from suppliers’ SDS were also consulted. Short term exposure limits (STEL) are usually for 15 min and long term permissible exposure limits (PEL) for 8 h. a) Respirable airborne particles Engineering Controls Ventilation Keep airborne concentrations below exposure limits. Because carbon black is bound to the liquid mixture; the airborne hazard is present only if the conditions of use could result in aerosolization or misting. RECOMMENDATION: If the product is heated at high goggles. RECOMMENDATION: Use safety glasses with lateral protection (side shields). Skin Protection Wear appropriate protective clothing to prevent skin contact. RECOMMENDATION: Use of protective gloves in butyl rubber, latex, neoprene, or other chemically resistant gloves. Respiratory Protection If exposed to vapors, wear respirator such as a half-mask respirator. RECOMMENDATION: Consult your local safety supply store to ensure your respirator has filter cartridges appropriate for the ingredients listed in section 3 of this MSDS, and that the respirator is fitted to the employee by a professional. Ensure vapor cartridges are stored in sealed plastic bags when not being used. General Hygiene Considerations Wash hands thoroughly with water and soap after handling. Physical State Liquid Eyes, ingestion, inhalation, and skin Symptoms Summary Eyes Causes serious eye irritation. May also cause eye redness or pain. Skin May cause mild to moderate skin irritation and allergic skin reactions. Inhalation Not a likely route of exposure due to low volatility. Inhalation of vapors or mist may cause irritation to the nose, throat and lung (upper respiratory tract). Ingestion Not a likely route of exposure. No acute toxicity effect known. See skin and inhalation symptoms. Chronic Prolonged or repeated exposure to the uncured epoxy resins used may cause dermatitis and sensitization.

Aspiration hazard

Viscosity at 40 °C is >>20.5 mm2/s, thus not classified as aspiration hazard. The ecotoxicity of the mixture was estimated by the calculation method using the summation of classified ingredients. The IMDG Code criteria and the raw-material MSDS along with supporting data for the classification of registered substances from the European Chemical Agency database (http://echa.europa.eu) were used. In Europe, similar epoxy resins with CAS# 28064-14-4 are generally classified as category 2 marine pollutant due to LC50 96 h of >1 mg/L but ≤10 mg/L. Chronic toxic effects have been suggested. Acute Ecotoxicity Category 2 GHS Code: Hazard Statement H401: Toxic to aquatic life P273: Avoid release to the environment P391: Collect spillage Chronic Ecotoxicity Category 3 GHS Code: Hazard Statement H411: Toxic to aquatic life with long lasting effects P273: Avoid release to the environment P391: Collect spillage Biodegradability The content is not readily biodegradable.
