For additional information on toxicity from scientific journals or registration documents, see the "Additional Resources for Toxicity " section of the chemical detail page. Washington (DC). Following the risk evaluation methodology developed under section 200 of CEPA 1999, the categories (flammability, combustibility, oxidizers, inhalation toxicity, aquatic toxicity, carcinogenicity, corrosiveness, pool fires) having the lowest scientific threshold will be compared against other risk management considerations. Signal word Danger. 2005. 2015. Federal Register, 59(20). Excessive dust generation creates a potential explosion hazard. Calcium dihydroxide is composed of one calcium cation and two hydroxide anions. Following the risk evaluation of calcium hydroxide, solution and taking into consideration the quantities in use in Canada, Environment Canada recommends that this substance be proposed for addition to Schedule 1 of the Environmental Emergency Regulations under CEPA 1999 at a threshold quantity of 3 tonnes with a minimum concentration of 0.1% and at a pH ≥ 11.5. Calcium hydroxide. Indicates high toxicity in the given toxicological category. SPILLS Sweep up dry spillage where possible and minimize flushing with water. Because calcium hydroxide, solution does not have a vapour pressure greater than 10 mmHg (1.33 kPa) at 25°C (CHEMINFO, 2010), the substance does not have sufficient volatility to constitute an inhalation danger. Refer for medical attention. 2014. After preliminary consultation, the proposed threshold for strong acids and bases has been increased to 3 tonnes with a concentration set at 0.1%. * Breathing Calcium Hydroxide can irritate the nose, throat and lungs causing coughing, wheezing and/or shortness of breath. * Contact can severely irritate and burn the skin and eyes with possible eye damage. Environmental exposure controls : Avoid release to the environment. Health issue . Blisters. Because calcium hydroxide, solution does not have an identified flash point (no flash point data were available during the data gathering process) and decomposes before reaching its boiling point (Genium, 2007), this substance does not have the possibility of a vapour cloud explosion. 1305-62-0) in use in Canada indicates that the substance exists in commerce. MATERIAL SAFETY DATA SHEET. Fever, sneezing, runny nose, sore throat, and pneumonia are some of the severe consequences of coming in contact with this chemical. CALCIUM HYDROXIDE TWA 5 mg/m3 US. Because calcium hydroxide, solution is not classified in any group of International Agency for Research on Cancer (IARC, 2014) or the U.S. Environmental Protection Agency (U.S. EPA, 2005), and because the substance does not have an identified half-life (no half-life data were available during the data gathering process), no threshold is set for the carcinogenicity of this substance.
