Where is 8 in. Class 1500 non-pressure Asbestos Cement sewer pipe allowed for installation?

  1. Aboveground inside a building

  2. Aboveground outside a building

  3. Underground under a building

  4. Exposed to direct sunlight

The correct answer is: Underground under a building

Class 1500 non-pressure Asbestos Cement sewer pipe can only be installed underground, not aboveground or exposed to direct sunlight. Installing it aboveground or in direct sunlight can lead to deterioration and potential health hazards from the asbestos material. Additionally, installing it under a building ensures that it is protected from physical damage and can properly function as a sewer pipe.
