ACGIH Sensitization
Wood (CAS N/A)
Dermal sensitization
Respiratory sensitization
Respiratory sensitization
Exposure to wood dusts can result in hypersensitivity,
Skin sensitization
Exposure to wood dust can result in the development of contact dermatitis. The primary irritant
dermatitis resulting from skin contact with wood dusts consist of erythema, blistering, and
sometimes erosion and secondary infections occur.
Germ cell mutagenicity
No component of this product present at levels greater than or equal to 0.1% is identified as a
mutagen by OSHA.
Carcinogenicity
May cause cancer by inhalation.
This classification is based on an increased incidence of nasal and paranasal cancers in people
exposed to wood dusts.

1 Carcinogenic to humans.

Reproductive toxicity
This product is not expected to cause reproductive or developmental effects.
Specific target organ toxicity -
single exposure
Not classified.
Specific target organ toxicity -
repeated exposure
Not classified.
Aspiration hazard
Not likely, due to the form of the product.
Chronic effects
Chronic exposure to wood dusts can result in pneumonitis, and coughing, wheezing, fever and the
other signs and symptoms associated with chronic bronchitis. Individuals with pre-existing disease
in or a history of ailments involving the skin, kidney, liver, respiratory tract, eyes, or nervous
system are at a greater than normal risk of developing adverse effects from woodworking
operations with this product.
Further information
The effects of industrial exposure to the chrome-copper-arsenic preservative used to treat CCA
wood has been evaluated in three independent epidemiology studies. In each case the authors
concluded that workers exposed on a daily basis to these preservatives were at no increased risk
of death or disease as a result of their exposure.
Recreational exposure to children using CCA treated wood playground equipment has been
evaluated. The results of this study indicate that the amount of arsenic transferred from the wood
surface to the child is within the normal variation of total arsenic exposure to children and that the
maximum risks of skin cancer associated with the exposure approximates the skin cancer risk
from the sunlight experienced during play periods. Leaf, stem, and fruit of grape plants grown
adjacent to CCA treated wood poles did not take up preservative components from the poles
above background levels (limit of detection 0.2 and 0.05 ppm for chrome and arsenic,
respectively).
