What is friction's role in cargo securement, and why is it not enough by itself?
- A.Friction between cargo, deck, and any mats helps resist sliding, but securement must still restrain the load against the regulated forward, rearward, and side forces
- B.Friction alone legally secures any load
- C.Friction does not exist on steel decks
- D.Mats replace all tiedowns
Correct answer
A. Friction between cargo, deck, and any mats helps resist sliding, but securement must still restrain the load against the regulated forward, rearward, and side forces
Why
Friction mats raise resistance and are worth using, but the rules are written around forces in a hard stop or swerve that friction alone cannot guarantee. Blocking, bracing, and tiedowns provide the positive restraint friction cannot.
