Question 115 of 180

Why is proper blocking and bracing especially important when loading hazardous materials in individual containers, such as drums, rather than a single bulk load?

Pick an answer

Individual containers are inherently immune to shifting during transit
Blocking and bracing rules apply only to bulk tank loads, never to individual drums or containers at all
It only matters for containers holding non-hazardous cargo
Individual containers can shift and collide with each other, increasing the risk of a puncture or leak

Correct!

Correct answer to question 115 (Hazardous Materials): Individual containers can shift and collide with each other, increasing the risk of a puncture or leak

Why

Individual containers like drums can shift and strike one another if not properly blocked and braced, and that kind of impact could puncture a container and release its contents, so securing them well is important.
