MIL-STD-101 Color Code For Pipelines And For Compressed Gas CylindersThis standard establishes a common color code for visual warnings to accompany the written identification of materials covered in piping systems and contained in compressed gas cylinders, and to facilitate the segregation of these cylinders at depots. This standard does not define the manner or conditions under which these materials may be used safely.
