In my line of work, fire spinning,  we use titanium alloy (with aluminum and vanadium) on a kevlar wick fueled with Coleman camp fuel to add a sparkling effect to the flame. We have recently had inquiries regarding the safety of inhalation of titanium alloy fumes. While I realize that toxic fumes may be produced, does anyone have any input about the level of danger created by burning approximately .3 oz of titanium alloy over a 5 minute period in a ventilated area? Thanks!

Has there been any reported nose and throat irritation ?

Not that I know of.

Hmm ,titanium dioxide is produced from burning the metal, with a recommended exposure level of 2.4 mg/m3
So it would depend on how open the area is and burn rate

[jeffro61]

Burn rate is approximately .06 oz a minute.

And it is usually outdoors so a very open area.

You may like to look up the properties of vanadium oxides as well, some are very toxic, not sure which are generated by burning though.

V2o5 is considered a poison but TiOxide is the whitener in lots of foods and medicines, inc toothpaste so apart from lung irritation TiO2 is food grade -well without the coleman fluid
