Limestone is mainly calcium carbonate, CaCO3. tyres, shoes, toys), wood (e.g. flooring, furniture, toys, construction materials, curtains, foot-wear, leather products, paper and cardboard products, electronic equipment), outdoor use in long-life materials with high release rate (e.g. Also Read: Building Lime […] Guidance on safe use - recommendations by substance registrant on the proper use of the substance in various situations. cutting of textile, cutting, machining or grinding of metal) and industrial abrasion processing with high release rate (e.g. Upon contact with water, quicklime would increase its temperature above 150 °C (302 °F) and ignite the fuel. The chemical lime in the form of Calcium Hydroxide (aka Edible Lime, Hydrated Lime, CaH2O2) is used in some food processing, and has been for millennia.Lime (in the form of Calcium Hydroxide) is used in South America in processing corn. This substance has been found in the following regulatory activities (directly, or inheriting the regulatory context of a parent substance): Welcome to the ECHA website. The source of the information is mentioned in the introductory sentence of the hazard statements. It is known by many common names such as hydrated lime, caustic lime, builder’s lime, slack lime, cal, milk of lime and pickling lime etc. Light: When quicklime is heated to 2,400 °C (4,350 °F), it emits an intense glow. Stolpa, Debbie and Marilyn Herman. The precautionary measures and guidance on safe use are as submitted to ECHA by registrants under the REACH Regulation. The ‘Hazard classification and labelling’ section shows the hazards of a substance based on the standardised system of statements and pictograms established under the CLP (Classification Labelling and Packaging) Regulation. Occupational exposure limit (OEL) values are derived within two legal frameworks that form an integral part of the EU’s mechanism for protecting the health of workers. According to the classification provided by companies to ECHA in REACH registrations this substance causes serious eye damage, causes skin irritation and may cause respiratory irritation. They are obtained by the process of calcination of natural limestone over a temperature of 900-degree Celsius. tyres, treated wooden products, treated textile and fabric, brake pads in trucks or cars, sanding of buildings (bridges, facades) or vehicles (ships)) and indoor use in long-life materials with high release rate (e.g. Other release to the environment of this substance is likely to occur from: outdoor use in long-life materials with low release rate (e.g. Limestone, which contains less reactive material, is slower to react and may have other disadvantages compared with It may then evolve into burns with perforation of the nasal septum, abdominal pain, nausea and vomiting. inside a watch) or with very low concentrations considered not to pose risks to human health or the environment. The EC Number is the numerical identifier for substances in the EC Inventory. This has been done for millennia. The CLP Regulation makes sure that the hazards presented by chemicals are clearly communicated to workers and consumers in the European Union. release from fabrics, textiles during washing, removal of indoor paints).
