WHOA.
Can't even have the stuff in the same room with me.
AAAAAAAACHOO! ItchItchItch!
Yeah, I don't seem to have any sensitivity to any of the tropical woods.
The worst for me is when I was teaching and had to work with alot of Eastern white pine. Maybe because of the resinous nature, or because of the sheer volume that I used to work with in my early days, but it can make me sneeze occasionally. Of course it helps that most of my work produces shavings rather than dust by the nature of the tools and techniques employed.

The Cocobolo Dust Eater...
...although I grant you that if you are truly sensitive even the above isn't adequate.
The Aggazani band saw in the pic has two dust ports and does pretty darn well when re-sawing.
It should have a third where the saw blade comes off the upper wheel - then it would really be clean.

I had a student once who I gave a small piece of Honduran mahogany to for a tiny box with lid. He ended up breaking out in hives.
Personally, I have done whole rooms in the stuff with 10' tall raised panel walls that required a week straight at the shaper. Even with dust collection I would be so covered in dust at the end of the day that I could write on my bare arms in the dust and blow heinous goo out of my nose. It turned the shower floor red for a while. Still, no reaction.

Quite a few softwoods and hardwoods are toxic to one degree or another and varying in how individuals react to them. The Dalbergia spp (so-called rosewoods) are for sure pretty nasty but many others are too. Another is the pterocarpus spp such as African Padauk. I remember when a whole cabinet shop crew was hospitalized here in the Bay Area back in the eighties with pulmonary edema from working a padauk project, according to my Higgins LBR rep back then. And some woods will develop hypersensitivity in subjects also, workers becoming more and more responsive to the toxins. Perhaps one of the least recognized problems is plicosis and sequiosis, from Western Red Cedar and Redwood respectively. There is quite a bit online about it if anyone is interested; it centers around sawmills with men exposed over long periods of time. Of course this comment is apart from the separate issue of wood dust in general and the assorted efficacies of particle sizes vis a vis lung tissue.

Wow!! I cant compete with all these projects, log homes, boats etc...
I am in the midst of rebuilding a engine for my Land Rover 130 which is my home away from home on many of my trips.

Interesting Peter-
I developed an allergy to Port Orford Cedar and Yellow Cedar (really a Cyprus) and can no longer work with them in any situation where we are milling. Insane how much milling we did back then without any respirators or vacuum systems.

Maybe in six months or so I'll turn this into a Thradd.

I'm also very sensitive to cedar. If I get a sliver in 5 min it starts to fester. Breathing cedar dust is out of the question.
Nice spot @ Shasta, Kat.

Some photos from my house. Took 3 summers to do , but it's the way we want it. 3.5 miles from the grid and 99% our own work.

The basic building blocks of wood (cellulose, lignin, polyoses), aren’t hard on the respiratory system as far as chemistry is concerned. What is a problem for our bodies and usually other animals/pets is certain toxins that some woods possess along with a very separate issue of certain particle size ranges of ANY wood. The size issue relates on a mechanical level to the foreign matter being able to involve itself with lung and mucous tissues adversely and certain sizes harder to expel than other sizes. Apparently there is a mid-range that is the nastiest. This may be “organic dust toxic syndrome”. And unsurprisingly what makes wood exactly toxic to us often seems correlated to that wood being highly resistant to insect and fungal attack.
But back to the main point and for instance, often the “sweet floral quality” of rosewood at first seems fabulous while huddled over it with tools and machines. . However as the hours and days mount up, usually that smell becomes a huge issue in the workplace. Soon everyone there is absolutely hating that smell and feels that it is now a giant irritant. And this situation develops even with good dust collection as we are there dealing with chemicals which are now aerosol. So other common aromas that start out fun but become horrid within hours are from: Western Red Cedar, Port Orford Cedar, Tennessee Red Aromatic Cedar--- actually ALL of the Cedars; Spruce; Redwood; Teak; all the Cypresses; Douglas Fir; Teak; “African Teak”/Iroko, the Walnuts; Anegre; the Ebonies; All the Rosewoods especially Cocobolo; Mansonia.
And woods that you can work with day and day out and not become hypersentized to are ones like Birch, Maple, Cherry, the Pines, Pecan/Hickory; Basswood; Balsa; and so on. The Oaks (red and white spp) are kind of borderline for most and often are mildly irritating. The Pines can also tip the scales to annoying also.
Interestingly there are a few woods that actually outright stink. Australian Walnut is the worst I have experienced; it smells like cat sh*t or worse.
In sum, toxicity is not only shared by many hardwoods but is also a problem in many softwoods. And part of the mechanism is ever increasing hypersensitivity during exposure. There is also some evidence of nasal cancers among species and uses.
Products derived from woods such as Cedar Oil and Pine Oil as well as their chips and shavings are also effective in knocking out insects, nematodes. It turns out that the livers of many pets actually cannot “do” these substances. Even horses will sometimes break out in papules all over their bodies or in contact areas as a result of exposure to cedar or redwood bedding.
And lastly, one other problem encountered is the presence of moulds in damper climate sawmills and related facilities. Another large discussion obviously.
Good reading (inc references) on effects of wood on human physiology:

Give up? OK, it is a full scale mockup of a stainless steel escutcheon for a thermometer to be mounted on a BBQ hood. It will be spray-painted to look like stainless for a marketing presentation.

I devoted last Spring to a batch of six stainless steel resophonic guitars.
Everything but the tuning pegs and strings was made in my shop.
