This isn't rocket science
Maybe people want to know why and how?
Some people (as in this case and topic title) think the reaction will cause a fire (never heard this one before).
Nothing over done. Some people want to know what and why, some people don't want to know anything and just do anything. Each to their own.
No different than anyone adding a sacrificial anode to a structure or even a car or boat. Same type reaction going on. Or, as another example, using non-zinc coated screws (hot dip galvanized) on a treated fence.
...In a wet environment dissimilar metals create a small electrical current that triggers a chemical reaction resulting in galvanic corrosion.
*shrug*
Rocket science to some, common sense to others.
