Howdy folks I as brewing a stout and the fermentation is off the charts. It foaming out over the airlock. What should I do from here it just keeps spitting out foam it is on day 2 of fermenting. Is my beer at risk of being infected? Ive never had this happen before so any advice is much appreciated

It's just a vigorous fermentation. First - wipe it clean with sanitizer then get a new air-lock - sanitize it and stick it in there.
You should be fine. You may have to repeat that procedure once more - but you should be fine. Ignore it and you'll be in trouble.

JonM is right - do it before it explodes!

This. Stat. And maybe move it somewhere slightly cooler and/or put it in a water bath to help slow things down. Unless you like mopping beer off the ceiling.

Dont move it to a cooler place to slow it down. It is very common for high gravity beers to have crazy fermentation. All you need to do is rig up a blow off tube into a container of sanitizer. If you used a 3 piece air lock you could just remove the cap and float pieces and stick a 1/2 inch tube in the airlock.

Yeah but I would be worried about temp if its fermenting like that. I had this happen with a Belgian Tripel 1.095 OG and even with a blowoff the bucket lid was about to blow. I removed the tube so it could just foam out through the grommet hole. Temps went up into the 80s even with the bucket at room temp sitting in the kitchen sink. The beer ended up very hot and solventy, fusels I think.

I totally understand, ive seen what a mess it can make when bucket lids blow off. I was going to recommend switching to a carboy or better bottle but i figure some people just prefer not to spend the money and like buckets.

Bucket, carbon, Better Bottle, warm fermentation, cold fermentation, high gravity, medium gravity--start everything with a blow off tube. After things slow switch to an airlock--or not.

Because carboys and BB can't blow off the airlock if it is clogged? It isn't a matter of the type of fermentor; rather it is about giving the krausen a place to go so that it doesn't clog the airlock and cause a blowout from backed up pressure. I have seen plenty of pictures of messy ceilings and walls from carboys blowing off airlocks.

Put a bag under / around it so it doesn't flood your floor, I always use a blowoff for first couple of days at least, just in case.
