for bath applications. Optimum stirring generally occurs at 10 centistokes and

Fume Point:
Indicates the point at which a fume hood or ventilation system
must be used to prevent health hazards posed by fume vapors. In the graph, it is
assumed that the bath access hole is covered at this point. This is subject to
user's company policy. Hart recommends the use of a ventilation system as
soon as the fluid produces vapors. Keep the access hole covered to reduce
evaporation.
