https://en.wikipedia.org/wiki/Titanium
As a powder or in the form of metal shavings, titanium metal poses a significant fire hazard and, when heated in
air, an explosion hazard.
[101] Water and
carbon dioxide are ineffective for extinguishing a titanium fire;
Class D dry powder agents must be used instead.
[7]
When used in the production or handling of
chlorine, titanium should not be exposed to dry chlorine gas because it may result in a titanium/chlorine fire.
[102] Even wet chlorine presents a fire hazard when extreme weather conditions cause unexpected drying.
Titanium can catch fire when a fresh, non-oxidized surface comes in contact with
liquid oxygen.
[103] Fresh metal may be exposed when the oxidized surface is struck or scratched with a hard object, or when mechanical strain causes a crack. This poses a limitation to its use in liquid oxygen systems, such as those in the aerospace industry. Because titanium tubing impurities can cause fires when exposed to oxygen, titanium is prohibited in gaseous oxygen respiration systems. Steel tubing is used for high pressure systems (3,000 p.s.i.) and aluminium tubing for low pressure systems.
