Elevators fire precautions

Precautions. The reagent is highly hygroscopic and is handled most satisfactorily in a dry box. Reactions are advisedly carried out in an inert atmosphere. It is caustic to skin and membranes. The reagent reacts exothermally with oxygen, and excessive exposure to oxygen or air at an elevated temperature presents a fire hazard. The flash point is 160-165°. 

When all the CaO has been added, the stirring is continued at a more leisurely pace for another three hours. This long stretch of stirring is bound to tire even the most dedicated explosive manufacturer so an alternative which can be used where electricity is available is to suspend an electric drill or similar motor over the pail, and use a clean paint stirrer attachment to stir the solution. The fumes are not especially flammable, so fires are not the hazard they often are when dealing with more flammable chemicals. Even so, rigging an extra long stem for the stirrer, so the motor is elevated above the pail rim, is a wise precaution.

Precautions in Use. The elevated temperature stress-corrosion resistance of this alloy in the presence of solid salt is lower than those of other commonly used titanium alloys. Use of Ti-5A1-2.5Sn (like all titanium alloys) in contact with liquid oxygen, or in contact with gaseous oxygen at pressures above approximately 345 kPa (50 psi), constitutes severe fire and explosion hazard.
