**Timeline of Efforts to Ban CCA **
and Arsenic in Treated Wood Products
The Rise and Fall of CCA Treated Wood
Date
Event
1880s
Creosote pressure-treated railroad ties first used in the United States.
1911
Copper Napthenate** first used** commercially as a wood preservative.

developed by the Celcure Company.
1933

1933
CCA Treated lumber is sold in Europe.
1938
CCA-A (the first CCA formulation) is
introduced in the United States.
1955
American Wood Preservers Institute (AWPI), a wood treatment industry group,
is established.
1968
CCA-C, the most widely-used formulation for Chromated Copper Arsenate,
is introduced.
1968
First report of a CCA-related worker injury occurred at Koppers, when workers fell ill after breathing CCA sawdust.
1968
Drs. Ferm and Carpenter publish study on birth defects caused by arsenic in laboratory animals. (1)](http://www.bancca.org/CCA_Timeline/CCA_Eventschart.html#Footnote1)
1972
Dr. Ronald Hood publishes additional studies on the teratogenic effects of arsenic on fetal development in mice. (2)](http://www.bancca.org/CCA_Timeline/CCA_Eventschart.html#Footnote2)
Mid-1970s
Germany bans CCA treated wood.
1978
EPA begins Special Review (RPAR) of CCA,
due to concerns that CCA exceeded the EPA’s own risk criteria for fetotoxicity/teratogenicity (birth defects), oncogenicity (cancer)
and mutagenicity (mutations).
Mid-1980s
Demand for CCA-treated lumber soars during the 5 year period of 1983-1988. (9)](http://www.bancca.org/CCA_Timeline/CCA_Eventschart.html#Footnote9)
Mid-1980s
Reports of CCA injuries begin to mount.
1983-1986
CCA injury case studies are published in medical journals,
including *The *Journal for the American Medical Association.
Scientists warn that:
“working with CCA treated lumber with power equipment in an enclosed area appears to pose a very severe health hazard”, and that
“vigorous measures [should] be taken to inform the lumber industry and the general public of the hazards of burning CCA treated wood…” (3)](http://www.bancca.org/CCA_Timeline/CCA_Eventschart.html#Footnote3)
1985
At the request of the EPA, the treated wood industry agrees to develop consumer information sheets as part of a voluntary Consumer Awareness Program (CAP) with important safety information to provide to consumers (end users) of wood preserved with CCA, creosote, or pentacholorophenol (penta).
These warning sheets were to contain steps to prevent potentially hazardous exposures to wood preservatives, and include handling, wood working,
and disposal precautions. (4)](http://www.bancca.org/CCA_Timeline/CCA_Eventschart.html#Footnote4)
1987
California Department of Health Services (DHS) issues report to the state legislature on the hazards posed by the use of wood preservatives
in playground equipment.
1988
**EPA concludes its Special Review of CCA and issues a new registration standard for inorganic arsenicals, which imposes additional conditions on CCA’s usages, but no restrictions on its use in treated wood . CCA is now classified as a restricted use pesticide. **
In addition, arsenic and hexavalent chromium are now classified as “class A carcinogens”.
The EPA acknowledges for the first time that both arsenic and chromium have the potential to cause teratogenic/fetotoxic effects.
Late 1980s
Canadian research scientist, Dieter Riedel of Health Canada,
conducts first research study into arsenic leached from playground equipment.
He tested 10 CCA wood playground structures and found arsenic on all 10 structures and in the soil around them.
His study was not published for a few more years.

“Project for Estimate of Risk of Skin Cancer from Dislodgeable Arsenic on Pressure Treated Wood Playground Equipment”.

The CPSC issues recommendations that:
- Treated wood manufacturers & playground equipment manufacturers develop procedures to reduce arsenic in treated wood products.
- Wood preservers should increase availability of their consumer information sheets.
- the exposure of consumers to arsenic during woodworking operations (sanding, sawing, etc.) should be reviewed.
1992
