IMO, there's enough clearance. The truck would have to drive onto the cement pad and wipe out the piping. How much clearance are you hoping for?
If you wanted to submit a recommendation, request a concrete bolard on either side of the panel, so long as adding them doesn't create a larger hazard. Such as having to maneuver around the post into the driving lane for access, or if they are too close and the door hits them or doesn't open all the way.

Yellow stripes in the pavement?

Yellow stripes in the pavement?

if you cant see the box ... how will you see the stripes?
no one will run into it if they can see it

Write up a safety procedure which includes cones and tape when the enclosure is being serviced.
When you're working on the controls, chances are the loading facility is out of commission

The way i see it , i wouldnt want ever to have to serve that box and an 18 wheeler behind me , with me having no idea if its coming straight to me or not, no amount of compensation will bring a person back or your limbs back, so thats my point of view, i believe they should take worst case scenario into account right now before an incident happens....

so do what wcord said, and expand on it if needed

No issue there. As the truck comes in, you step to the side. Once parked, go back to work..., when it leaves, step to the side again.
What am I missing? Is this a real issue? I get more nervous working on a lighting contactor with fork lifts buzzing around then a situation like this. In this case there are tons of egress routes!

That is a code compliant install as far as clearance goes. Clearance requirements are for required disconnects, panel boards and switch gear. Electrical boxes and enclosures only need to be accessible.

How often do your PLCs need servicing?

 

[gpop]

Biggest problem is going to be when a tanker pulls off with the hose attached and drags all the pipe work in to the panel. Second problem is going to be the vibration from a truck idling while filling or unloading but the panel looks like its going to be near the back of the trailer rather then up near the cab. No HMI or non led-lights so that should be ok.

Been explaining arc flash and egress at work on lift-station designs that have 480v. My kit can take the arc flash but i do not need to stumble backwards and end up falling into a lift station. OP's panel is not wired and the conduit is not in the concrete so maybe they would be open to turning the panel 90 degrees

Looks like a pretty typical small load/unload rack. Usually non drivers/chemical operators aren't allowed near the rack while transferring chemicals anyway.

At the plants we work at for any electrical or mechanical work we'd have to block of the truck lane or if it's a rail rack have the proper signs and derailers installed.

The major issue will be working in the panel. A safety plan needs to be created and enforced. What would have been wrong with rotating 90' when it was planted? Short of a vehicle jumping a curb, problem minimized.

There are forlifts working around this area continously when trucks are not loading.

Panel wont be moved but they agreed it needs extra protection so theyll mark the floor and install concrete poles .

 

[BillyMac59]

For extra protection consider a horizontal barrier supported by two bollards say 6' apart. Have brackets on the bollards that support the barrier. Instead of the tedious chore of unbolting it for panel access, it can be lifted aside easily by one guy ( or two if your union ...lol) ..... sorry; I'm an old union guy - couldn't resist !

 

[just the cowboy]

The only issue I would have is the step off as you backed up as a trip hazard, it don't look like 36" ground before the curb.
For the future they did not need the support gussets in the back and could of just used a better rack and moved it back.
