Final answer:
answer b,The standard color for marking pipes carrying oxygen is Green, according to ANSI/ASME A13.1 standard for the identification of pipes in the U.S.
Step-by-step explanation:
The standard designation color for marking pipes carrying oxygen is Green. This safety color coding is widely recognized and used to indicate oxygen lines in medical, welding, and industrial environments. The use of standardized color codes for pipe marking is crucial for safety, allowing workers to quickly identify the contents of a pipe and any potential hazards associated with it. It is important to follow the specific codes and standards that are used in the country or industry as they might differ from one place to another. In the United States, for instance, the ANSI/ASME A13.1 is the standard for the identification of pipes, which specifies green as the color for oxygen.
The correct answer is B. Yellow. In pipe labeling, color codes are used to denote the contents and potential hazards of the pipe. The color coding for oxygen is yellow. This is because oxygen supports combustion and can be highly reactive. Therefore, it is important to clearly identify pipes carrying oxygen to prevent accidents or mishaps.
