On the 49 CFR 176.83 segregation table, what does "1" signify?

The designation of "1" in the 49 CFR 176.83 segregation table specifically indicates "Away from." This classification is essential in transportation safety, particularly when it comes to handling hazardous materials. The segregation table is utilized to determine the appropriate distance that must be maintained between different types of hazardous cargoes during transport to minimize the risk of dangerous interactions that could arise from these materials being stored too closely to one another.

The notion of "Away from" suggests that while certain materials may not be incompatible to the extent that they cannot be transported together, they nonetheless require a specific distance for safety. This is particularly important in preventing potential chemical reactions, minimizing any risks of spills, and ensuring that any hazardous characteristics of one material do not adversely affect those of another in the event of a leak or exposure.

Understanding this classification is crucial for compliance with shipping regulations and ensuring the safety of both the vessel and the crew during transport.
