Are suspended acoustical ceilings safe to install & use?
Yes. INSTALLATION. Studies have shown that exposures during conventional installation are below all current occupational standards for nuisance and other listed substances (dust). If power tools are used in the installation, they should be equipped with special dust collection devices, and the workers should wear the appropriate NIOSH-designated respirators. IN-PLACE. Once installed, Armstrong ceiling products do not represent an identifiable health risk to the general building occupants.
