NOTE:
- Worn sodium-filled exhaust valves must not be scrapped without first being properly treated. The valves must be cut at the middle of the shaft using a metal saw. While doing this, do not come into contact with water. At the very most, throw 10 of the prepared valves into a bucket filled with water. Then, move quickly away, because a sudden chemical reaction will occur during which the sodium is burnt away. The treated parts may then be discarded through conventional disposal channels.
