To ensure safety against toxic fumes, which cable type is recommended?

Plenum cables are specifically designed for use in areas where they could be exposed to air circulation, such as in the spaces above ceilings or below floors where HVAC systems are present. These cables have a special fire-retardant jacket that helps prevent the spread of flames and reduces the amount of toxic fumes that would be emitted if the cable were to catch fire.

In environments where safety against toxic fumes is a concern, such as commercial buildings or data centers, it is essential to use cabling that meets safety standards for flame resistance and low emissions of harmful gases. Plenum-rated cables are able to do this, making them the recommended choice for such applications. Other types of cables, like CAT6, fiber, and coaxial cables, do not necessarily have the same level of fire safety specifications tailored for use in plenum spaces, thus making them less suitable for ensuring safety in those environments.
