  WARNING
Care must be taken when disposing of old sodium-cooled exhaust valves - risk of injury.
t  The valves must be sawn in two with a metal saw between the centre of the stem and valve head. When doing so, the valves must not come into contact with water.
t  Then throw a maximum of ten valves into a bucket of water and step away immediately.
t  A sudden chemical reaction will occur upon contact with water in which the sodium filling burns.
t  After performing these steps the valves can be disposed of in the normal way.
