    20 B:C

Answer

A rating of 5 B:C is the minimum required rating for a single fire extinguisher on a commercial power unit hauling non-hazardous cargo.
Under federal commercial vehicle safety regulations, a power unit transporting non-hazardous cargo must have either one fire extinguisher rated 5 B:C or more, or two extinguishers rated 4 B:C or more.

Step-by-Step Solution

1
Identify the cargo type and safety equipment specifications.
The vehicle is operating with non-hazardous general freight and uses a single fire extinguisher.
Fire extinguisher rating minimums vary depending on whether hazardous materials are transported and whether one or two units are used.
2
Apply federal commercial vehicle emergency equipment rules.
A single extinguisher on a non-hazardous transport vehicle must have a UL rating of at least 5 B:C.
This rating ensures sufficient chemical suppression capacity for burning liquids and electrical fires.
