Turn Running Lights Off, why?

I've seen plenty of dock procedures that make me wonder but this is a first for me. I can't figure out why. Most of my appointments are before sun up and I make it a habit of leaving my ambers on especially in tight and low-lit or no-lit docks. I'd ask the recieving clerk but she clearly hates human beings. Only thing I can think is if the unloaders sees brake/taillights under the dockplate he might think the truck is pulling out. Who's got a better answer to ease my simple mind?

 

If your in a place that ships famable products and they get a spill, your trailer electric may become the ignition source. If it comes in contact.

 

They have started a fire before when you have those bumpers/seal that go all around back of trailer

 

Heat from bulbs, non led, melting dock cushions? Never seen it, but.........?

 

Makes sense, I didn't think of that. It's at a food service paper supplier though but it's a new customer for us so perhaps they are new occupants and the signs are leftover.

 

Ok yea, the dock cushion thing makes sense if the trailer still has halogen bulbs. Now I get the bottom of the sign.

 

Incandescent marker lights contacting the dock bumpers, combined with long load/unload times, could constitute a fire hazard. With LED's it should matter less, but still, if they want the lights off, turn 'em off. Maybe they've actually had something catch fire once and are erring on the side of caution.

 

Now I had to delver to some weird dock, and there was that sign on the wall, I ignored it, but than was told why - the girl said it was because the driver's they have working there can't see with the lights on, some trucks have chicken lights on and there is such a tight fit they've had accidents because of them.

 

If the receivers know trucks are backing onto docks and want you to reverse without your lights switched on have they provided adequate lighting so you can see where your reversing? the only way they might learn is for drivers to refuse to unload, then they might get the picture.

 

You said food service and sense I haul food grade products its for the bugs. Lights attract bugs and bugs are no good in food grade buildings.
