What distance is represented by "2" on the 49 CFR 176 segregation table?

In the context of the 49 CFR 176 segregation table, the designation of "2" represents a required separation distance of 20 feet (6 meters) between certain hazardous materials. This distance is established to mitigate the risks associated with the possible release or interaction of hazardous substances during transport.

The segregation table is an important guideline used to determine the safe stowage of different classes of hazardous materials when they are being transported. Maintaining appropriate distances between different materials helps to prevent accidents and ensures safety on transport vessels.

In this case, the choice indicating 20 feet aligns with the regulatory requirements outlined in the Code of Federal Regulations, which aims to enhance safety measures and reduce potential hazards while handling and transporting dangerous goods.
