"Fire Extinguisher Type: Any means suitable for extinguishing surrounding fire"
A fire? In TiO2 ? What's the atmosphere on their planet ?
"Harmful if swallowed. May cause irritation."
Bullshit. It's not harmful, it won't cause irritation. Of all the world's powdered rocks, this is just about one of the dullest and most boring. It's a dust inhalation hazard solely because it comes in particles smaller than a nostril.
TiO2 is less harmful than a McD's burger.
