Safety issues for the storage of reactive material still apply.

The trench is then filled with the reactive materials (typically iron, carbon, or limestone).

Sand can be mixed with the reactive material to aid in allowing the water to flow through the materials.

Being a reactive material, cast iron can have chemical reactions with high acid foods such as wine or tomatoes.

Some plugs are made of thermally reactive material.

They are also subject to gradual failure due to using up the reactive materials, and may lose sensitivity in cold conditions.

Being completely inert may seem rather dull, but for industries that work with highly reactive materials, this absence of chemistry can be essential.

It is a potentially violently reactive material towards water and other nucleophiles.

When applied to a chemically reactive material, they can falsely evaluate it as non-stoichiometric.

It rates the reactive material as is grows, tracks the percentage of flow from the given nodes.
