2014 Health Hazard Evaluation Program Annual Report
The NIOSH Health Hazard Evaluation (HHE) Program is pleased to share its 2014 annual report with you! Our report includes summaries of projects that were interesting and other highlights of our year. We hope the report stimulates conversations about who the HHE Program is and how we make a difference for the health and safety of employees throughout the United States.

NIOSH Health Hazard Evaluation Program Noise Measurement Database
We have released a database to provide researchers and other interested stakeholders with noise measurement results collected during HHE surveys from 1996–2012. The noise database contains workplace noise measurement results from 73 HHE reports, including over 761 personal noise exposure measurements and 536 area noise measurements. For reports posted online, the database provides a direct link to the HHE report for each of the noise measurement results. This database is an ongoing project and will be updated at least yearly to add the most recent HHE noise measurement data. To view the database go to

Noise and Ergonomic Recommendations Provided to an Electronics Recycling Facility
Although employee exposures to metals in air were low, some employees were overexposed to noise and others may be at risk for low back injuries. HHE Program investigators recommended reducing noise levels, starting a hearing conservation program, and evaluating risks for musculoskeletal disorders. To read the full report go to

Indoor Environmental Quality Recommendations Provided to a College Campus Building
Although HHE Program investigators found no current water damage or mold, they did identify deficiencies in the ventilation systems and mixing of air between offices, classrooms, and a dental clinic. Investigators recommended checking with a ventilation engineer to change how return air is mixed and to improve airflow. To read the full report go to

Evaluation of an Electronic Scrap Recycling Facility
HHE Program investigators' evaluation of employee exposure to metals found some employees with blood lead levels above 10 micrograms per deciliter, a level considered elevated. Investigators provided recommendations to prevent exposure to lead and other metals and to prevent unintentionally exposing family members. To read the full report go to
