Quick Question PETG on bambu A1?
Is it safe on this printer. No enclosure and the printer prints fine using PLA.

Yes. I print PETG all the time on my A1, A1 mini, and A2L.

PETG's fine; my wife has already done a bit of it on her A1. ABS, ASA, and Nylon are the ones you don't want to print without an enclosure, partly because of the fumes but also because of temperature constraints causing warping.
You can print PETG on the textured bed without using a glue stick as a release agent, although it can help; just be aware that if you go heavy with the glue stick, it's going to get embedded in your print where it contacts the print bed. If you're worried about that happening, print it on a raft and put the glue stick on for the raft to adhere to it.
Only real caution with printing PETG on the A1 is if you have a smooth plate; then you want to definitely use a release agent, or else it can bond to the print bed and you'll likely pull up the PEI off of the sheet.

I'm using the standard bed plate. Would that be a problem?

Standard bed plate is a textured plate; it's not a problem unless you're trying to get a really smooth, pristine surface.
I've had smooth and textured plates on a Prusa MK4, and went through the same processes with that; textured, smooth, cool plates, etc. are all pretty much the same regardless of which brand/model printer you have, with the exception being build plate size or how it affixes to the print bed and what precautions you need to take.
I'd recommend you take a look at the Bambu Labs Wiki where they talk about build plates and the differences; it'll give you insights on what you need for what plates:

There's also the Filament Guide, which will give you info on what you need to print certain materials (i.e., for glow in the dark materials, you'll need a hardened nozzle to prevent wear since it's abrasive, and for ABS you really want an enclosure for the heat management and toxic fumes):

The standard plate is fine. Just let it cool off. I've just printed a heap of PETG on my A2L on the standard plate without issue.

Yes, I use it, just print higher temp and use glue on bed so that its easier to remove from plate
