* Note that Pressure treated lumber is banned in Berkeley and many other cities in uses where people would come into contact with it, such as handrails, playground equipment, and landscaping. It can still be used in foundation work where it is not exposed. The sawdust should be carefully collected and disposed of at a hazardous waste facility. OSHA Standard 1926.1148 warns of " limits for exposure to formaldehyde, a carcinogenic gas used in the production of engineered wood products such as plywood, OSB, MDF, particle boards and engineered trusses. Employees should be made aware of the dangers, and follow precautions when working with formaldehyde-treated wood products. Any operation that involved sawing, grinding or sanding... or any other manipulation that generates formaldehyde -bearing dust may require employee monitoring equipment to guard against excess exposure to formaldehyde." For a list of building materials with hazardous chemicals and safer alternatives, see the Green Building Reference Guide Glossary of Terms and Environmental Hazards.
