No.
Rule number one when reversing in a forklift: Watch where you're going. If the operator had been watching properly, they wouldn't have hit the racking.
Remember that counterweight forklifts start at around 4,000kg - so there is a bit of energy even in a slow moving one.
Also, the contact to the racking was a sideways motion compared to the normal approach where a forklift is placing or retrieving a load. A touch in that orientation might result in a slight sway movement - but this was one where a supporting beam was kinked, causing it to lose all vertical strength. With things tied together (for group strength and stability) having a few more sections fail is not a surprise. Seeing the whole right hand side of racking three aisles over collapse - well, that was surprising.
they are tightly spaced shelves, stacked too heavy and not secured properly. The employer fucked up. Maybe if they paid the guy 35 an hour hazard pay he might feel a bit embarrassed. This is a joke. That should not happen from a low velocity impact at a shallow angle. If he sped it up from across the room and crashed into it face first it would be different. This is a nudge.
Also like seanB said there should be posts. Someone is mental about density and cost in that place.
You can't be serious if you think a entire facility should fail from a low velocity crash at like a 5 degree angle? Can you even call it a crash? A scrape maybe?
You can also put company SOP in place that does not allow you to move around a obstruction and require someone to spot you when your backing up but that construction is shoddy as fuck.
I guarantee you they used the thinnest steel that would stand up strait when they were building those shelves, put them together with pop rivets and elmers glue.
What should have happened is a employee being chewed out over a scratched up forklift and a dented shelf.
