* Fire Extinguishing: Carbon tetrachloride was used in some fire extinguishers, particularly for electrical fires due to its non-conductivity. However, its use was phased out due to its toxicity and carcinogenic properties.
* Cleaning and Degreasing: It was used as a solvent in some cleaning and degreasing operations, but again, its toxicity led to its replacement with safer alternatives.
It's important to note that the use of carbon tetrachloride was becoming increasingly restricted by the 1960s due to its harmful effects:
* Toxicity: Inhalation of carbon tetrachloride vapors can damage the liver, kidneys, and nervous system.
* Carcinogen: It is classified as a Group 1 carcinogen by the International Agency for Research on Cancer (IARC), meaning it is known to cause cancer in humans.
As a result, the US Navy, along with many other organizations, began phasing out carbon tetrachloride in the 1960s and 1970s. This transition was driven by increasing awareness of its health risks and the development of safer alternatives.
