Safe-in-Sound Excellence in Hearing Loss Prevention Loss Awards - Group and Company Nominations Deadline TODAY!
Nominations for the annual Safe-in-Sound Excellence in Hearing Loss Prevention Awards are now being accepted. The awards are co-sponsored by NIOSH, the National Hearing Conservation Association (NHCA), and the Council for Accreditation in Occupational Hearing Conservation (CAOHC).
Two awards are presented: one for excellence and one for innovation. According to Safe-in-Sound Review Committee Coordinator, Scott Schneider, CIH, judges for the excellence award consider what nominees have done to limit or eliminate the risks from noise exposures in their workplace. Previous winners have been recognized for purchasing quieter tools or equipment, regularly checking noise levels, providing effective hearing protection tailored to workers’ needs, conducting careful analysis of the annual hearing test results, training all workers effectively on noise both on and off the job, controlling noise to the levels recommended by NIOSH, and evaluating their program each year to make improvements.
There are two deadlines for nominations. Those who wish to nominate another individual, group, or company must submit nominations by June 8, 2023. Self-nominations will be accepted through August 18, 2023. Winners are invited to receive the award and present their real-world success stories at our annual NHCA Conference, February 8-10, 2024, in Albuquerque, NM.
