ICC Certified Fire inspector One Practice Test

How many chocks and what size must tank vehicles carrying flammable or combustible liquids carry?

1. 2 5"x5"x12"

2. 3 4"x4"x8"

3. 1 6"x6"x10"

4. 2 3"x3"x6"

The correct answer is: 2 5"x5"x12"

Tank vehicles carrying flammable or combustible liquids are required to maintain safety by having the appropriate number and size of chocks. The correct answer specifies that these vehicles must carry two chocks measuring 5 inches by 5 inches by 12 inches. This requirement ensures that the chocks are sufficiently large and robust enough to effectively immobilize the vehicle when it is parked, reducing the risk of accidental rolling or movement. The specified size (5"x5"x12") provides a balance between manageability and effectiveness. Smaller or fewer chocks would not offer adequate support or stability, increasing the potential hazards associated with transporting volatile materials. The other options either provide insufficient numbers, incorrect dimensions, or do not meet the regulatory standards necessary for safely securing tank vehicles during loading, unloading, or stationary periods. Hence, the specified requirements correlate closely with safety practices outlined in relevant regulations and industry standards.
