Hi, we are home economists at AnswerLine and this question is a bit outside of our area of expertise. You may want to contact Doug Stokke at dstokke@iastate.edu. He should be able to assist you.

I've found this information at The Wood Preservation and Wood Products Treatment Training Manual from Oregon State University.


Wood pressure-treated

with creosote

Consumer information—This wood

has been preserved by pressure treatment

with an EPA-registered pesticide containing

creosote to protect it from insect attack and

decay. Wood treated with creosote should

be used only where such protection is

important.

Creosote penetrates deeply into and

remains in the pressure-treated wood for a

long time. Exposure to creosote may present

certain hazards; therefore, the following

precautions should be taken both when

handling treated wood and in determining

where to use the treated wood.

Use site precautions—Wood treated with

creosote should not be used where it will be

in frequent or prolonged contact with bare

skin (for example, chairs and other outdoor

furniture) unless an effective sealer has been

applied.

Creosote-treated wood should not be used

in residential interiors. Creosote-treated

wood in interiors of industrial buildings

should be used only for components that

are in ground contact and are subject to

decay or insect infestation, and for wood

block fl ooring. For such uses, two coats of

appropriate sealer must be applied. Sealers

may be applied at the installation site.

Wood treated with creosote should not

be used in the interiors of farm buildings

where the wood may be in direct contact

with domestic animals or livestock that may

crib (bite) or lick the wood. Creosote-treated

wood may be used for building components

that are in ground contact and are subject

to decay or insect infestation; however, two

coats of an effective sealer must be applied.

Sealers may be applied at the installation

site. Coal tar pitch and coal tar pitch

emulsion are effective sealers for creosotetreated

wood block fl ooring. Urethane,

epoxy, and shellac are acceptable sealers for

all creosote-treated wood.

Avoid frequent or prolonged inhalation of

sawdust from treated wood. When sawing

and machining treated wood, wear a dust

mask. Whenever possible, these operations

should be performed outdoors to avoid

indoor accumulations of airborne sawdust

from treated wood. When power-sawing or

machining, wear goggles to protect eyes.

Avoid frequent or prolonged skin contact

with creosote-treated wood. When you

handle the treated wood, wear long-sleeved

shirts and long pants. Use gloves that are

impervious to the preservative (for example,

gloves that are vinyl coated). When you are

power-sawing or machining, wear goggles

to protect your eyes. After working with

the wood, and before eating, drinking, or

using tobacco products, wash exposed body

areas thoroughly. If preservatives or sawdust
