Bruckner JV, MacKenzie WF, Muralidhara S, Luthra R, Kyle GM, Acosta D. This investigation was conducted to characterize the acute, subacute, and subchronic toxic potency of ingested carbon tetrachloride (CCl4). EPA has one year to propose and take public comments on any risk management actions. Environmental Medicine Branch. Isopropyl alcohol potentiation of carbon tetrachloride toxicity has been shown previously only in rats. United States Environmental Protection Agency. This educational case study is one in a series of self-instructional modules designed to increase the primary care provider’s knowledge of hazardous substances in the environment.

The Centers for Disease Control and Prevention is authorized by IACET to offer 0.1 CEU's for this program. The products are intended for educational use to build the knowledge of physicians and other health professionals in assessing the conditions and managing the treatment of patients potentially exposed to hazardous substances. carbon tetrachloride to reactive species is the initial key event in the development of carbon tetrachloride toxicity. To take the initial check, read the case below and then answer the questions that follow. Because CCl4is chemically stable, it has a long atmospheric half-life. Continuing Competency credits available are 1.5 CDC provider number 98614. Fees: No fees are charged for CDC’s CE activities. Physicians should claim only the credit commensurate with the extent of their participation in the activity. Current OSHA PEL: 10 ppm TWA, 25 ppm CEILING, 200 ppm 5-min MAXIMUM PEAK in any 4 hours. Unreasonable risks to workers and occupational non-users can come from long-term inhalation or dermal (through the skin) exposures. Answer to: Carbon tetrachloride reacts at high temperatures with oxygen to produce two toxic gases, phosgene, and chlorine. Also critical to carbon tetrachloride toxicity are cellular antioxidant systems that function to quench the lipid peroxidation reaction, thereby preventing damage to … This program is designed for Certified Health Education Specialists (CHES) and/or Master Certified Health Education Specialists (MCHES) to receive up to 1.5 total Category I continuing education contact hours. Use of trade names in ATSDR products is for identification purposes only and does not imply endorsement by the Agency for Toxic Substances and Disease Registry or the U.S. Department of Health and Human Services. CARBON TETRACHLORIDE is a commonly used liquid in fire extinguishers to combat small fires. The next step in the process required by TSCA is risk management. CDC, our planners, content experts, and their spouses/partners wish to disclose they have no financial interests or other relationships with the manufacturers of commercial products, suppliers of commercial services, or commercial supporters. For example, carbon tetrachloride safety data sheets developed by the manufacturer remind users to only use the product in well-ventilated areas. CE Original Date: December 31, 2017 CAS number: 56–23–5 NIOSH REL: 2 ppm (12.6 mg/m 3) 60-minute STEL; NIOSH considers carbon tetrachloride to be a potential occupational carcinogen as defined by the OSHA carcinogen policy [29 CFR 1990]. What Instructions Should Be Given to Patients? When you are using this chemical, please be cautious about it as the following: Contact Us to ask a question, provide feedback, or report a problem. While EPA is working through the process required by TSCA to address the unreasonable risks found from carbon tetrachloride, the information below provides ways to reduce exposure. The products are not a substitute for a health care provider's professional judgment. In the final risk evaluation, EPA reviewed 15 conditions of use, all of which are associated with industrial and commercial work and primarily involve the manufacturing of other chemicals. Read about the steps in EPA’s risk evaluation process for carbon tetrachloride. Planners have reviewed content to ensure there is no bias.
