<P>The following information is reprinted with permission from data =
provided by=20
Roy Banner, a wood turner from Torrance, California who almost lost his =
life in=20
1989 to anaphylactic shock after turning pieces of exotic wood. You can =
bet Roy=20
wears his RACAL respirator every time he turns on his lathe now! Roy has =

assembled this data over the years from various sources and when an =
entry=20
appears in <FONT color=3D#ff0000>red</FONT>, this indicates that the =
information=20
has come from only one source and has not been verified elsewhere. Some =
of the=20
information here has come as a surprise to me and its a wonder I've =
never had a=20
toxic reaction to wood that I've been aware of. As a luthier, I've =
worked with a=20
lot of exotics, but as a wood collector I've worked with lots more =
strange stuff=20
from all over the world with no ill effects. Each of us is different and =
you can=20
call me old "iron gut".
<P>Sorry that this file is such a patchwork effort and may be difficult =
to=20
follow, and that Latin names of woods are not included. I can't judge =
with any=20
authority the validity of the information presented here and it's up to =
the=20
user's discretion to further research any wood themselves, though Roy =
has told=20
me the information here has appeared in several woodworking magazines =
(for what=20
that's worth). Take this as a jumping off point. You might also want to =
check=20
out <A href=3D"http://bodd.cf.ac.uk/Indexes/PlantFamilies.html">The =
Botanical=20
Dermatology Database</A>.

<HR>
After each wood name comes categories between slashes / /:
<P>
<UL>
  <LI><B>Class:</B> Woods are either an <FONT =
color=3D#0000ff>irritant</FONT>=20
  which cause a reaction fairly rapidly after exposure and will cause a =
similar=20
  reaction repeatedly, or <FONT color=3D#0000ff>sensitizers</FONT> which =
may have=20
  a latency period of hours or months and may require repeated handling =
before=20
  reaction occurs. Sensitizer's are the more severe, because once you're =

  sensitized, you're sensitized for life and the reactions only get more =

  dramatic. A bit like paying taxes to the Gov, huh?=20
  <LI><B>Reaction Category:</B>=20
  <UL>
    <LI><FONT color=3D#0000ff>Eye and skin</FONT> irritation (hives, =
itching,=20
    redness).=20
    <LI><FONT color=3D#0000ff>Respiratory</FONT> problems.=20
    <LI><FONT color=3D#0000ff>Nausea</FONT>, headache, or general =
malaise,=20
    possibly even liver or kidney malfunction.=20
    <LI><FONT color=3D#0000ff>Cancer</FONT> of nose and sinus. =
Statistics show=20
    that woodworkers have a 40 per cent greater chance of nasal cancer =
than the=20
    general population, but the majority of statistics on nasal cancer =
are based=20
    on data from 1920-1960 when the furniture industry became highly =
mechanized=20
    with little or no dust control methods. So don't freak. </LI></UL>
  <LI><B>Potency:</B> <FONT color=3D#0000ff>Small, great, =
extreme</FONT>. This is=20
  the potential of the wood or sawdust doing harm and would vary with =
the=20
  individual i.e., those who are allergy prone might think twice about =
working=20
  with wood classed as extremely potent.=20
  <LI><B>Source:</B> <FONT color=3D#0000ff>Dust or wood</FONT>, or both=20
  <LI><B>Incidence:</B> <FONT color=3D#0000ff>Unknown, rare, or =
common</FONT>.=20
  This is probably the vaguest of the categories as most doctors =
wouldn't know=20
  an allergic reaction to wood if it bit them in the face. =
</LI></UL>Note that=20
this data does not take into consideration Man's penchant for trying to =
poison=20
himself by using formaldehyde in plywood, treated woods, sodium =
compounds in=20
white pine to prevent blue stain, etc.
