Default explosive fermentation

So i brewed a pumkin ale on sunday night and when i got home on monday the lid from my fermenter was popped off and there was wort all over my carpet I quickly put the cover back on but im not sure if everything is cool. I figure im gonna continue with the fermentation and just hope that it didn't get contaminated.

Don't sweat it, it happens to us all one time or another. In the future use a blow-off for the first few days of fermentation, then switch to an airlock once things settle down.

So airlocks are restrictive enough to pop a lid off a bucket? wow...

I'll have to start getting consistant with my active fermentations before I'll be having this problem I'm sure. my last batch made the airlock gurgle for about 4 days only.

My next batch I'm possibly going to primary in one of my new Carboys which I'm sure hold the pressure different than a fermenting pail.

I do 5-gal batches in a 6.5 glass carboy, and have done beers up to about 8% ABV, and never had krausen reach the airlock. Been close, though For me at any rate, less than 8% beers and 5 gal in a 6.5 carboy, with airlock, works fine. But heed the other's advice on blow-offs. Such a simple thing to do to alleviate concern.

not just gravity, but the type of yeast comes into play.

wheat and belgian yeasts like to go nutso even with lower gravities at times

Not just gravity nor the yeast strain, but if you add any real fruit (puree as opposed to flavor extract--pumpkin counts as the former) it's always a good idea to have a blowoff tube.

airlocks are only restrictive when fermentation causes the krausen to plug up the tiny holes in the bottom of the airlock. and then it goes POP!

I have been using a blow off tube in my primaries (not to hijack this thread) but I don't think it is wide enough.
I just did a coffee stout from 4#'s of LME, 6#'s of DME, and a now unknown yeast, (was a liquid, bring to room temp, shake and pitch at 70-75F). I had a blow off tube and it still blew the top off the bucket. It is the fairly small diameter tube that I use to bottle and siphon with. The primary is a plastic primary Fermenter bucket, about 6 gallons big. I believe with a glass 6.5 carboy I could alleviate a lot of these problems. Fermentation temp was around 60F.
Has anyone else perfected the Blow-off tube?

I use 6.5 Gallon Carboys for my Primary Fermentation. I use a Blow Off tube That gets shoved into the neck of the Carboy. A very snug fit. The other end of the blow of tube is submerged in a Plastic Gallon Container that is filled with a Star Sans Solution. Make sure that the hose is submerged in the Star Sans solution. Once fermentaion slows in a couple of days, I then place an air lock on top of the Carboy. I can't remember the diameter of the Blow Off tube that I use, but I am positive that any reputable LHBS could help you out. I have been using this type of Blow Off system for a little over 14 years of Brewing. Works like a Charm and have never had an issue.
