|
|
| 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 |
| 4 |
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 |

|
For all glues: avoid formaldehyde; use water-based glues, instead
of solvent-based; wear gloves/barrier creams, goggles, dust mask; use good
ventilation; avoid flames |
| 14 |
PAINT STRIPPING |
Other solvents highly toxic/moderately toxic |
Methylene chloride highly toxic; other solvents highly
toxic/moderately toxic |
Methylene chloride moderately toxic; other solvents highly toxic/
moderately toxic |
Carcinogenic; flammable; corrosive; bleach + ammonia highly
toxic |
Use Dimethyl adipate strippers; use solvent-based strippers
outside; use ventilation, respirator; avoid open flames; wear gloves,
goggles; have eyewash fountain, emergency shower available; avoid torches,
heat guns |

PAINTING & FINISHING |
Pigments haz., min. spirits, turpentine moderately toxic |
Pigments haz., min. spirits, turpentine moderately toxic |
Mineral spirits, turpentine moderately toxic |
Ethyl & Methyl alcohol slightly toxic to moderately toxic;
flammable, combustible |
Use ready-made, water-based paints; don't eat, drink, smoke in
painting area; wear gloves, goggles, respirator; use ventilation; spray in
spray booth; use ethyl, NOT methyl alcohol; AVOID glycol
ethers |
