1 WOOD HAZARDS




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
7 GLUING WOOD




8 Epoxy Glues
Moderately toxic Moderately toxic Moderately toxic by eye contact
9 Cyanoacrylate Glues
Long-term effects not studied Moderately toxic Moderately toxic by eye contact; can glue skin together
10 Formaldehyde-Resin Glues
Highly toxic Moderately toxic Highly toxic by eye contact; carcinogenic
11 Contact Adhesives Other solvents moderately toxic Hexane highly toxic; other solvents moderately toxic Other solvents moderately toxic Mineral spirits, naptha, 1,1,1-trichloroethane are other solvents
12 Water-Based Glues Not significantly toxic/slightly toxic Not significantly toxic/slightly toxic Slightly toxic

13 Dry Casein Glues Highly toxic Highly toxic Moderately toxic
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
15 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
