Final answer:
Copper pipes should not be used for chemical or industrial waste requiring pretreatment due to potential corrosion when in contact with certain chemicals. Cu/Fe pipe joints can lead to rapid corrosion, which is why this option is not recommended.
Step-by-step explanation:
The specific material in question that should not be used for chemical or industrial waste that requires pretreatment is Copper pipes (Option A). Copper can corrode when in contact with certain chemicals, leading to potential contamination and structural failure of the piping system. In the provided exercises, a plumber proposes using copper pipes to replace lead ones to prevent lead poisoning.
However, the problem with copper pipes arises when they are joined with iron, as the Cu/Fe pipe joints can lead to rapid corrosion, especially if the water has a high mineral content, or there is a significant amount of oxygen in the water. It is essential to choose the right piping material when dealing with specific substances to maintain safety and integrity.
