Carbon tetrachloride, also known by many other names (such as carbon tet for short and tetrachloromethane, also recognised by the IUPAC), is a chemical compound with the chemical formula CCl 4. It is a non-flammable, dense, colourless liquid with a "sweet" chloroform-like odour that can be detected at low levels.
The handling of this chemical may incur notable safety precautions. It is highly recommend that you seek the Material Safety Datasheet for this chemical from a reliable source such as SIRI, and follow its directions. MSDS for carbon tetrachloride is available at Fisher Scientific.
It is a field of study within occupational safety and health and public health. [3] Short term risks may include physical injury (e.g., eye, back, head, etc.), while long-term risks may be an increased risk of developing occupational disease , such as cancer or heart disease .
Tetrachloroethylene is regarded as a toxic substance, a human health hazard, and an environmental hazard. [ 5 ] [ 7 ] In 2020, the United States Environmental Protection Agency stated that "tetrachloroethylene exposure may harm the nervous system, liver, kidneys, and reproductive system, and may be harmful to unborn children", and reported that ...

From plastic cutting boards to nonstick pans, these 5 kitchen staples have been linked to potential health hazards. Korin Miller. October 10, 2024 at 9:11 AM.
The highest level cited for a concentration of carbon tetrachloride (seemingly of highest concern) is 459 micrograms per cubic meter, translating to 0.073 ppm (part per million), or 73 ppb (part per billion). The OSHA-allowable time-weighted average concentration over eight hours is 10 ppm, [30] almost 140 times higher;
Many gases have toxic properties, which are often assessed using the LC 50 (median lethal concentration) measure. In the United States, many of these gases have been assigned an NFPA 704 health rating of 4 (may be fatal) or 3 (may cause serious or permanent injury), and/or exposure limits (TLV, TWA/PEL, STEL, or REL) determined by the ACGIH professional association.
