What type of support is typically NOT used for gas piping according to NFPA 54?

Metal hangers
Wooden blocks
Brackets
Metal bands

The correct answer is: Wooden blocks

In the context of gas piping installation according to NFPA 54, wooden blocks are generally not considered suitable support. This is because wooden blocks can deteriorate over time due to moisture, pests, and environmental factors, leading to potential structural failure. Gas piping requires reliable support to maintain alignment and prevent stress on joints, and materials like metal hangers, brackets, and metal bands are designed to be durable and resist environmental influences. These options are also more likely to meet the code requirements for strength and stability, ensuring a safe installation that mitigates risks associated with gas leaks or pipe failures.
