---|---|---|---|---|---|---|
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 |
