The seal is thin, so as not to prevent the handle from being used (in due time), but only to alert maintenance/security personnel that the handle was indeed used. Many times, large sea-going shipping containers have such a metal ring or seal attached to them at the source port.
Since the arc testing method is not dependent on water making good contact through the leak, it is more sensitive and comparatively easy to perform in most types of liner construction (ponds, Landfills, tanks etc.)than the water-based methods. The minimum sensitivity of the arc testing bare geomembrane liner integrity method is a pinhole leak.

A can seamer is a machine used to seal the lid to the can body. The lid or "end" is usually tinplated steel (food) or aluminum (drinks) while the body can be of metal (such as cans for beverages and soups), paperboard (whisky cans) or plastic. The seam formed is generally leak proof, but this depends on the product being canned.
The dangers of a can that is not hermetically sealed are contamination by foreign objects (bacteria or fungicide sprays), or that the can could leak or spoil. One important part is the seamer setup. This process is usually performed by an experienced technician. among the parts that need setup are seamer rolls and chucks which have to be set in ...
Automatic belt chamber sealers require the entire product to be placed in a plastic bag or flow wrapped pouch within the machine. The product travels on the conveyor belt, it is automatically positioned in the machine on the seal bar, the lid is closed and air is removed. Then a seal bar inside the chamber seals the product in the bag.
A water detector is an electronic device that is designed to detect the presence of water for purposes such as to provide an alert in time to allow the prevention of water leakage. A common design is a small cable or device that lies flat on a floor and relies on the electrical conductivity of water to decrease the resistance across two contacts.
