WOOD
HAZARDS
Hardwoods
Dusts irritating, can
cause pneumonia
Saps, lichens,
liverworts irritating
Inhalation can
cause nasal or
nasal sinus cancer
Use common hardwoods,
instead of rare, tropical ones;
use ventilation/respirator; wear
gloves/barrier cream; avoid
sensitizing woods
Softwoods
May be irritating
May be irritating
May cause nasal
or nasal sinus
cancer
Use common softwoods; use
ventilation/respirator; wear
gloves/ barrier cream; avoid
sensitizing woods
Formaldehyde highly
toxic
Formaldehyde
moderately toxic
Carbon monoxide,
hydrogen cyanide,
phenol can also be
released
Use low-formaldehyde
products; don't store large
amounts of the wood in the
shop (store in ventilated area);
dust collectors should be
exhausted to the outside
