What type of materials should be used in corrosive environments?

• A. Use standard sprinklers.
• B. Use copper piping only.
• C. Use corrosion-resistant materials.
• D. Use corrosion-resistant materials.

Answer: (C)

In corrosive environments, the materials used for the sprinkler system must resist corrosion to keep the system reliable over time. Standard sprinklers and copper piping aren’t automatically corrosion-proof in all harsh conditions, and they can deteriorate, leading to leaks or impaired discharge. Using corrosion-resistant materials—such as stainless steel components or coatings and appropriate corrosion-resistant piping options listed for the environment—helps preserve system integrity and longevity. Matching material properties to the environmental conditions is essential so the system performs when needed. So, corrosion-resistant materials are the correct choice.
