>Formic acid is caustic and should be handled with care.

>limits have been established by OSHA for worker safety.
>According to the information I have the time-weighted-
>average is 5ppm.

>Individuals differ in their ability to detect formic acid
>but no one should rely on odor.  Respirators, chemical
>resistant gloves, safety goggles, and other protective
>equipment must be worn when handling formic acid.

>Research in Europe and North America has shown that

>tracheal mite.  I believe the first label submitted to
>EPA will be only for the control of the tracheal mite.
