Fume Point: The fume point is the point at which a fume hood should be used.
This point is very subjective in nature and is impacted by individual tolerance to
different fumes and smells, how well the bath is covered, the surface area of the
fluid in the bath, the size and ventilation of the facility where the bath is located
and others. We assume the bath is well covered at this point. This is also subject
to company policy.

Flash Point: The flash point is the point at which ignition may occur. See flash
point discussion in Section 8.1.8. The point shown may be either the open or
closed cup flash point.
Boiling Point: At the boiling point of the fluid the temperature stability is difficult
to maintain. Fuming is excessive. Excessive amounts of heater power may be
required because of the heat of vaporization.
Decomposition: All high temperature fluids may reach a temperature point at
which decomposition of some form will begin. While it always begins slowly at
some lower temperature, the rate can increase to the point of danger or
impracticality at a higher temperature.
