Packing group Packing group : III 14.5. This quantity for spills of 3 tonnes in NEMISIS is also the same as the quantity recommended by TDG for their ERAP for sulphuric acid, nitric acid, hydrobromic acid and perchloric acid (Environment Canada, 2015). Safety Data Sheet according to 29CFR1910/1200 and GHS Rev. One spill of sulfuric acid was identified as having a “major” impact at 4.5 tonnes. Likely hazards to health or the environment. Indicates high toxicity in the given toxicological category. Burning sensation. 4. First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. Even if the quantity of a substance in use is below the threshold quantity indicated in the Environmental Emergency Regulations, Environment Canada recommends that emergency planning be applied to this substance in order to minimize, or prevent, any impacts on humans or the environment in the event of a release of the substance. Calcium hydroxide (CAS TWA 5 mg/m3 1305-62-0) US. Therefore, no threshold is set for this substance as a result of its potential for flammability or combustibility. benign, health . OECD (Organisation for Economic Co-operation and Development). U.S. EPA (U.S. Environmental Protection Agency). Environmental Health: substances that are: corrosive, persistent, bioaccumulative, or aquatically toxic. form salts with inorganic bases such as CALCIUM HYDROXIDE. The substance is irritating to the respiratory tract. 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.
