I hate to be so
cruel, but this one actually caused a colleague to tear from the laughter!
This is the definition in the booklet (Honest!)
"Fibers are solid particles whose length is several times greater than their diameter, such as asbestos."
Here is an
extremely vague, misleading and outright WRONG definition of a fiber! This OSHA
definition is the definition of a geometric three-dimensional solid called a
"cylinder." Applying OSHA's definition of a fiber, here are some
other "fibers" you should not have in the air that your workers
breathe:
A flagpole, a worm,
a salami, a rope, a pin, a bread stick, a glass rod, and (for those treckies) the
probe that invaded the earth in Start Treck V!
For your benefit,
here is Webster's definition of a fiber: "A thread or a
structure or object resembling a thread as:
1) A slender root (as of grass.)
2) An elongate pairing cell that has at maturity a small lumen and
no protoplasm content that is found in many plant organs and is especially
well developed in the xylem and phloem of the vascular system and
that implants elasticity, flexibility, and tensile strength to the plant
or organ.
3) The axis cylinder of a nerve cell with its sheath
4) One of the structures composing most of the intercellular matrix
of ordinary and elastic connective tissues.
5) A natural or man-made object that has a length usually many
hundred or thousand times greater than its width, that possesses
considerable tensile strength, pliability, and
resistance particularly against heat, some chemicals
