This project will develop a noise control Start Printed Page 44540technology database consisting of powered hand tools used in the construction industry with respective sound power levels and workers' 8-hour time-weighted average noise exposure level. The sound power level and workers' exposure level data will be acquired in a hemi-anechoic laboratory by NIOSH researchers. The database will facilitate the use of engineering noise controls by gathering precise information on the effectiveness of existing control technology. The principal product of the study and the primary method of information dissemination will be the searchable web-site database of powered hand tools used in the construction industry with respective operational specifications, sound power levels, and workers' exposure level. This database and specific information on noise control applications also will be disseminated through practical guidelines, handbooks, and case study reports to aid safety and health professionals, noise control engineers, equipment and noise-control systems' manufacturers, and trade associations in applying effective noise control technologies.

Comments are invited on:

1. Whether the proposed database will be useful for its planned purposes;

2. Ways to enhance the quality, utility, clarity, and dissemination of the information to be collected;

3. Whether the study population is properly targeted and whether access to the study population is feasible; and

4. Whether the makes and models of powered hand tools with respective sound power level data or simply generic terms should be reported in the sound power level database.

The Director, Management Analysis and Services Office, has been delegated the authority to sign Federal Register notices pertaining to announcements of meetings and other committee management activities, for both CDC and the Agency for Toxic Substances and Disease Registry.
