The meter bank outside has a sign that reads "WARNING TO COMPLETELY DE-ENERGIZE BUILDING SERVICE DOSCONNECT 1 & 2 MUST BE OPENED"

Should I assume the incoming power is 240V/2 Phase.

Two phase is pretty rare, so not sure why you would assume two phase?
I would guess there is an other set of meters with a second service disconnect at another location. It would be better if that sign gave you the location of the other service disconnect.

If you zoom in on the breakers, I see 4 Pole breaker. So I assume it was a 2 Phase breaker
 
If you look closely at the labeling inside of the two meters at the lower left, you could check whether 2-phase is mentioned or not.
 
I would bet don (in post #2) has it correct. There is likely a 2nd service disconnect (possibly the disconnect to the left just out of the picture)
The "4 pole breakers" are likely just a standard factory assembly for that manufacturer's 2 pole breaker.

As Augie stated it's a standard 2 pole circuit breaker.

Please update your profile to include a profession.
 
See the weather covers broken off in 5 of 8 meter disconnects. The breakers are showing the effects of being exposed to the weather for a while. I wouldn't assume a 2 phase just because of the 4 space breaker. Seen a lot of GE with that configuration even on 200Amp. Not sure why they use that configuration vs a 2 space like many other mfg use.

I agree, seems like that code section also requires the location of the second service disconnect be labeled also.

A GE engineer told me they're paralleled for current sharing.

I'll try getting a better look at the label the next time I go, but if I remember correctly, I think it was all faded away.

I usually 2 Phase in Philly but this project was located in NJ which threw me off weather it was 2 Phase or not
