How many fire extinguishers and what size are required on a pickup truck hauling explosives?

• A. 1 extinguisher 4A 20-BC
• B. 2 extinguishers 4A 20-BC
• C. 2 extinguishers 4A 60-BC
• D. 3 extinguishers 3-A 40-BC

Answer: (B)

When hauling explosives, the emphasis is on having enough fire suppression ready and rated for the hazards you’re carrying. The standard requirement is two fire extinguishers, each with a rating of 4A 20-BC. Having two extinguishers provides redundancy—if one is used or blocked, you still have another to attack a developing fire and give you a chance to evacuate safely. The 4A 20-BC rating means it’s capable against common fires involving ordinary combustibles (A), flammable liquids (B), and electrical fires (C), which covers the range of fire types you might encounter in and around a vehicle carrying explosives. While a higher-rated extinguisher could also meet safety goals, the material’s typical standard specifies the two-unit, 4A 20-BC setup as the required configuration, and a single extinguisher wouldn’t meet the two-unit rule.
