According to NFPA 54, how should gas piping be supported?

  1. By wood blocks

  2. By metal hangers, hooks, bands, or brackets

  3. By attaching to walls only

  4. By using concrete anchors

The correct answer is: By metal hangers, hooks, bands, or brackets

Supporting gas piping according to NFPA 54 requires the use of metal hangers, hooks, bands, or brackets, which ensures the integrity and safety of the piping system. Metal supports are durable and less likely to degrade over time compared to alternative materials like wood. Proper support helps maintain the alignment of the piping, prevents sagging, and mitigates the risk of stress fractures or leaks, which could lead to dangerous conditions. Using wood blocks, attaching to walls only, or relying solely on concrete anchors can potentially compromise the system's stability or lead to damage. These alternatives may not offer the same strength, adjustability, or long-term reliability as metal supports, making option B the appropriate choice for maintaining the safety and effectiveness of gas piping installations.
