Things to look out for are:
- Don't run around (you could run into someone or something)
- Only bottled water, this is so that no other drink or food gets into the equipment
- Be wary of trailing cables on the floor, you could very easily trip up on them (I have in my studio)
- Noise level, you don't want to damage your hearing just because you want to play REALLY LOUD!!!
It is important to stay hydrated during your time in the performance hut, but bottled water really is the way forward. If you spill a bit of water on a piece of equipment that is off, it might be alright because the water will evaporate. However if you were drinking a can of Coca Cola and then spilled it on the mixing desk then that could be a disaster because there will be a sticky residue on all the components.
