Removing gas from oxyacetylene equipment is known as

1. Bleeding the lines

2. Flushing the system

3. Purging the tank

4. Venting the hoses

The correct answer is: Bleeding the lines

Removing gas from oxyacetylene equipment is known as "bleeding the lines" because this process involves opening the valves and allowing the gas to escape until the lines are free of any remaining gas, ensuring the safety of the equipment and the operator. Flushing the system typically refers to cleaning out the system with a solvent or cleaner. Purging the tank is a process of removing any remaining gases or impurities from a tank or container. Venting the hoses can refer to releasing pressure from hoses but may not fully remove all the gas from the equipment.
