Sawdust has been coming under a lot of scrutiny as a possible health
hazard and even casual woodworkers who are in frequent contact with
sawdust -- breathing and/or touching it -- should consider some important
facts.
Some time ago, The Vermont Lung Association (a national center for lung
diseases) conducted a pulmonary function (breathing) survey among workers
exposed to hardwood and pine dusts.
When the survey was completed, the results indicated that wood dust
was a possible health hazard. The study concluded:
1. The prevalence of “low pulmonary flow rates” (impaired
breathing) among woodworkers who were exposed to medium and high amounts
of hardwood dust were two to three times higher than among persons who
were not exposed.
2. The prevalence of “low pulmonary flow rates” among woodworkers
who were exposed to high amounts of pine dust were two to four times
higher than among those who were not.
The results of this study should be of particular concern to part-time
woodworkers who already have a medical problem such as emphysema, asthma,
or allergic reactions to certain woods.
There’s no doubt that the air in a home shop environment can become
highly concentrated with sawdust. Under these circumstances, Dust Masks
and an effective Dust Collection System can go a long way toward keeping
your shop clean and pleasant -- and help make it a healthier, safer
place to work, as well.
Make it a practice
NEVER to do a lot of sawing, sanding or dust-producing work in your
shop without a dust mask, a top quality dust collection system and adequate
shop ventilation (open a couple of windows and use fans to exhaust any
dusty air that escapes your dust collector).
Be aware of allergic reactions that may present themselves as a result
of breathing or touching certain woods. For example, Walnut dust frequently
produces both respiratory problems (sneezing) and skin rashes on lots
of woodworkers. Some people even report feeling a “tingling”
sensation when they touch certain domestic or exotic hardwoods. If you
feel such sensations, take steps to protect yourself.
Like most hobbies, woodworking is not 100% devoid of all potential problems.
All of us are affected in some way by wood dust…some more than
others. Be aware of any potential allergies or problems you may be having
and take the necessary steps to correct them.
