Just like any large warehouse, they need an exhaust system to vent dangerous fumes.

  From the bit of time I did working in warehouse software, all the indoors warehouses I've seen were exclusively using electric forklifts, specifically because gas/oil coulnd't be used because of the fumes.

    LNG is also common.

      Around here they would use propane instead. OT: Recently the fire department called me because the carbon monoxide detector in one of my buildings alarmed. That was mysterious since in the summer the furnaces are not used. Eventually we discovered that the cleaning crew was using propane-driven buffers on the floor! We're not going to allow that anymore. It's a 6000 sq ft office that is mostly carpeted; they certainly don't need to use dangerous equipment that was designed for large buildings like sports stadiums.

That large open hole in the roof probably helps. See the video at 2:48.

They have exhaust fans in different parts of the underground that pull air from the entrances

You still need ventilation systems with electric vehicles. A lot of stuff produces particulates or vapors that need to be vented out.

  Actually you need ventilation also for the actual humans. A common "standard" for mines/tunnelling is: 3 Cubic meters/minute per worker 4 cubic meters/minute per diesel HP (calculated on the max power output of the engines) Electric vehicles (battery powered) are usually not considered as they normally represent a fraction of the power involved in the construction/digging. The large machines that are electrically powered (via cable/wire) are not included as they do not produce exhaust fumes nor particles/vapours, but they may be considered in some cases for the amount of heat they produce.

I did some work at a wolframium mine in Portugal, and all the workers would come down the mine in 4x4 pickups. All the excavators and heavy machinery were diesel as well. Somehow, there wasn't a lot of smoke under the ground - I guess the ventilation system must have been really good.
