What activity is prohibited under Texas law regarding fire extinguishers?

Selling carbon tetrachloride extinguishers is prohibited under Texas law due to the hazardous nature of carbon tetrachloride. This chemical is known to be toxic and poses serious health risks, including potential harm to the liver and kidneys, as well as being a potential carcinogen. The discontinuation of carbon tetrachloride fire extinguishers aligns with safety regulations emphasizing the importance of using safer alternatives for firefighting equipment. This prohibition helps to mitigate the risk of exposure to dangerous substances for both consumers and emergency responders.

The other activities listed, such as refilling, transporting, and testing fire extinguishers, are generally permissible but must adhere to specific safety standards and regulations to ensure the effectiveness and reliability of the extinguishing equipment.
