Use a blow off tube for the start of every brew. Some yeasts are more prone to blowoff but any might. If the airlock gets clogged it could blow out with enough force to splatter the ceiling with krausen.
Better to install the tube and not need it than to have to clean the ceiling!
If you want to avoid the entire mess that Nottingham produces (especially above 64-65 degrees) increase the headspace in the fermenter to allow for the krausen. I use a bucket that allows plenty of room and don't worry about oxygen because of the CO2 produced in the fermentation. 5 gallons in a 6 1/2 gallon bucket usually provides enough room for krausen.
To bad i can't post video lol i just got home after trying to find a one inch outside diameter hose at the hardware store without luck so i changed my airlock with a clean one after sanitation and as soon as i placed it it began bubbling and hizzing lol i guess this will teache a lesson to always have a blow tube available ...below is a picture of the clean airlock that has already started to get dirty lol
