Compressed gas containers are not to be used for which purpose?

The use of compressed gas containers for grounding is incorrect because grounding is typically a method used to ensure safety by preventing electric shock and ensuring that excess electricity is directed safely to the ground. This involves using conductive materials that can ensure a secure path for electrical current. Compressed gas containers, on the other hand, are designed to store gases under pressure for purposes such as storage, hosting gases for operations, or testing systems. Using them for grounding would not only be ineffective but could also pose serious safety risks, as the integrity of the gas container could be compromised, leading to potential accidents or hazardous situations. Proper grounding requires specifically designed equipment that can handle electrical energy safely and effectively.
