Which of the following must NEVER be loaded with hazmat cargo?

The Segregation Table (49 CFR 177.848) lists materials that must not be loaded together because they react dangerously with each other. The simplest 'do not load together' combinations include: cyanides with acids (releases hydrogen cyanide gas), oxidizers with flammables (severely worsens fires), and certain radioactive materials with corrosives in metal containers (corrosion of the radioactive container). The table also lists 'distance' requirements where small physical separation is acceptable. Drivers should consult the table for every multi-material load. The shipper is primarily responsible for ensuring loads are compatible, but the driver shares legal responsibility and can refuse to transport an unsafe combination. 'Compatibility' is not a suggestion — incompatible loads have caused fatal incidents.
