One of the biggest worries is, of course, fire. Make sure you have a good fire extinguisher:
Sometimes the power will go off, leaving you all alone is a pitch-black studio filled with tables, wheels, wet clay, sleeping dogs to trip over.... An emergency lighting system is a must.
Of course, if you can afford it, an auxiliary power supply is even better.
Industrial accidents are another big concern. As they say, accidents do happen. Make sure you are prepared.
And if all else fails, make sure you have what you need to call for help.
With a little foresight, you ought to be able to enjoy years of happy potting without disaster. All it takes is a little advance planning.
