No, a beam clamp is not a recognized device for grounding an electrical panel in an industrial setting.
The only problem that can happen is you would not have a ground for your electrical in the house if the pipe is cut between the clamp and the copper going into the ground outside. You shouldn't get shocked, if that is what you're worried about.
Purchase a ground rod from an electrical supply. Drive it into the ground just outside where your service is located. Install a ground cable from the neutral bar in the fuse box to the ground rod and clamp both ends. Voila, you have done it!

A cold water pipe is usually a ground. Nowadays with plastic pipe you can't be sure. If the pipe out of the foundation is copper chances are it is good. You can check it with a meter. You can also get an electrical ground rod and install it. It is just a 10' spike that you hammer into the ground and clamp a wire to. It will also give you a good ground. You may already have one at your home. Check by the service entrance for electricity and phone.

All electrical distribution systems require a system earth ground for personnel safety. The ground for your home electrical system is likely a grounding rod, a 10 ft. copper clad steel rod driven into the ground and then bonded with a brass clamp and large bare ground wire to your panel. This provides a path to ground to dissipate errant current which can occur due to a circuit which "shorts out." Better it goes to ground than into you!
Simply "clamp-on" the clamp of the amp meter to any electrical conductor supplying the equipment that you wish to check while it is in operation. It is better to use your clamp-on with each individual conductor one at a time.

Using a water pipe ground clamp and securing the ground wire to the cold water pipe as it goes into the building BEFORE the water meter is one way. A better way is to drive an 8-foot ground rod into the ground and secure it via a ground rod clamp. My employer and I actually try and use both methods together.
Because there may be a spark when you connect a jumper cable negative clamp to the battery post which can cause an explosion. Batteries emit hydrogen gas which is very volitive. Always connect the negative clamp to the engine or another ground point on the vehicle.
