|
| 2 |
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 |
| 3 |
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 |

Plywood & Composition Board |
Formaldehyde highly toxic |
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 |
| 5 |
Wood Preservatives & Other Treatments |
Pentachlorophenol highly toxic, chromated copper arsenate extremely toxic |
Pentachlorophenol highly toxic, chromated copper arsenate extremely toxic |
Pentachlorophenol highly toxic, chromated copper arsenate highly toxic |
Carcinogenic; creosote carcinogenic; zinc, copper napthenate moderately toxic (if ingested) |
Obtain MSDS's for chemicals used; don't handle woods treated w/pentachlorophenol creosote; don't machine CCA-treated wood; use zinc/copper napthalene; wear respirator; use ventilation; don't burn the wood |
| 6 |
CARVING & MACHINING WOOD |
|
Dusts haz. |
Dusts haz. |
Machines noisy; accidents from tools; hand damage; shock; fire |
Equip machines w/dust collectors; place outside; wear respirator, goggles, face shield; vacuum sawdust; don't use noisy machines; have machine guards; cut away from you; have panic buttons |
