Why must edge protection be used where a strap passes over a sharp cargo edge?
- A.Edge protection is only cosmetic
- B.A sharp edge can cut or severely weaken the strap under tension and vibration, causing a sudden loss of securement
- C.Straps cannot be cut by metal edges
- D.It makes straps tighter automatically
Correct answer
B. A sharp edge can cut or severely weaken the strap under tension and vibration, causing a sudden loss of securement
Why
Webbing under load is vulnerable at corners, and road vibration saws it against the edge mile after mile. Edge protectors preserve the strap's rated strength and are themselves an inspection item when missing where an edge threatens the tiedown.
