When treating a wasp nest it is never known how explosive the reaction will be. Most nests will react strongly with a small number of extremely aggressive individuals. Some nests like this one literally explode with all the individuals highly aggressive.
It is probably due to factors such as ambient temperature and dust penetration/nest destruction.
If you ever attempt doing wasp nests yourself it is best to do them in the night time. Make sure you know exactly where the entrance hole is and treat using a dust. Wasps are cold in the night and don’t see well in the dark so there is practically no reaction.
