GHS 분류This chemical does not meet GHS hazard criteria for 4.8% (1 of 21) of reports.DangerH315 (95.2%): Causes skin irritation [Warning Skin corrosion/irritation]P264, P264+P265, P280, P302+P352, P305+P354+P338, P317, P321, P332+P317, and P362+P364 (click each P-code to see the statement)Aggregated GHS information provided per 21 reports by companies from 2 notifications to the ECHA C&L Inventory. Each notification may be associated with multiple companies.
규제 정보Chemical: Calcium oxide silicate (Ca3O(SiO4))Calcium oxide silicate (Ca3O(SiO4)) is listed on the EPA's Chemical Data Reporting (CDR) system. Manufacturers and importers of Calcium oxide silicate (Ca3O(SiO4)) are required to report information about their production and use of this chemical to the EPA under the Toxic Substances Control Act (TSCA). (40 eCFR Part 711)Tricalcium silicate: Does not have an individual approval but may be used as a component in a product covered by a group standard. It is not approved for use as a chemical in its own right.

유해성 요약Wet cement has a pH of >12 and can cause severe burns after prolonged contact[HSDB] See Portland cement.
FDA 요건Tricalcium silicate used as an anticaking agent, tolerance 2%, is generally recognized as safe when used in table salt in accordance with good manufacturing practice.Tricalcium silicate used as an anticaking agent, tolerance 2%, is generally recognized as safe when used in table salt in accordance with good manufacturing or feeding practice.
Hazard Classes and CategoriesSkin Irrit. 2 (95.2%)
처리 방법SRP: The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational harm/injury/toxicity or environmental contamination. Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider: the material's impact on air qualitypotential migration in soil or watereffects on animal and plant lifeand conformance with environmental and public health regulations.
유해 작용Dermatotoxin - Skin burns.
Probable Routes of Human ExposureAccording to the 2006 TSCA Inventory Update Report, the number of persons reasonably likely to be exposed in the industrial manufacturing, processing, and use of tricalcium silicate is 1,000 or greaterthe data may be greatly underestimated(1).NIOSH (NOES Survey 1981-1983) has statistically estimated that 62,383 workers (433 of these were female) were potentially exposed to tricalcium silicate in the US(1).
Antidote and Emergency Treatment/SRP:/ Immediate first aid: Remove patient from contact with the material. Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR if necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on the left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. /Inorganic Bases/Alkaline Corrosives and Related Compounds//SRP:/ Basic treatment: Establish a patent airway (oropharyngeal or nasopharyngeal airway, if needed). Suction if necessary. Watch for signs of respiratory insufficiency and assist ventilations if necessary. Administer oxygen by nonrebreather mask at 6 to 12 L/min. Monitor for pulmonary edema and treat if necessary ... . Monitor for shock and treat if necessary ... . For eye contamination, flush eyes immediately with water. Irrigate each eye continuously with 0.9% saline (NS) during transport ... . Do not use emetics. For ingestion, rinse mouth and administer 5 ml/kg up to 200 ml of water for dilution if the patent can swallow, has a strong gag reflex, and does not drool ... . Do not attempt to neutralize. Cover skin burns with dry sterile dressings after decontamination ... . /Inorganic Bases/Alkaline Corrosives and Related Compounds//SRP:/ Advanced treatment: Consider orotracheal or nasotracheal intubation for airway control in the patient who is unconscious, has severe pulmonary edema, or is in severe respiratory distress. Early intubation, at the first signs of upper airway obstruction, may be necessary. Positive-pressure ventilation techniques with a bag valve mask device may be beneficial. Consider drug therapy for pulmonary edema ... . Monitor cardiac rhythm and treat arrhythmias as necessary ... . Start IV administration of D5W /SRP: "To keep open", minimal flow rate/. Use 0.9% saline (NS) or lactated Ringer's (LR) if signs of hypovolemia are present. For hypotension with signs of hypovolemia, administer fluid cautiously. Consider vasopressors if patient is hypotensive with a normal fluid volume. Watch for signs of fluid overload ... . Use proparacaine hydrochloride to assist eye irrigation ... . /Inorganic Bases/Alkaline Corrosives and Related Compounds/
