I am hoping to catch a couple of folks that have their own small regulator repair businesses run out of their home through either local or mail order clients. I will soon have a custom breathing air and regulator test bench system that Nuvair out of Oxnard, CA has helped me piece together. At first, I thought that it would be good for filling my own tanks and working on my own regulators but, was wondering about possibly doing some work on the side for other folks. For those of you who do this, do you have some type of liability insurance that covers you in the event that something goes wrong? If so, where would one get this type of insurance coverage? Thanks in advance for your thoughts.
