Liability for damage as a self-employed person

Questioner

Hello, I have a question. I am a self-employed person and have hired myself out to a paint shop. I don't have an employment contract, I just started working here on an hourly basis. While I was working there, a spray hose sprang a leak. It was an old hose that had already been shortened several times, but that's beside the point. I have good insurance, but the company I worked for charged me for this hose. which means I cannot arrange this through insurance Is this what they're allowed to do? I told them beforehand that I had good insurance. Now he has bought a very expensive hose package of 20 meters long and according to them this costs 512 euros.

Apparently, the client believes you caused the damage and that you should therefore pay for it. However, it's questionable whether you are liable. Furthermore, any agreements you may have made with your client in this regard are also important. Feel free to call me to discuss this without obligation.
