NHCA 2021 Virtual Conference has ended
Welcome to the 2021 NHCA Virtual Conference Schedule, below you will find the schedule listed with 3 types of education sessions, Live Platform, Pre-recorded Platform and E-Poster Sessions. They will all be delivered a little differently so please take a little time to read the descriptions and understand how the conference will be laid out.

  • Live Platforms: NHCA is offering 7 live sessions with interactive Q&A and chat features over the two days of the live conference. If you are not able to watch these sessions live they will be recorded and playback will be available until March 19, 2021
  • ON DEMAND Pre-Recorded Platforms: There will be 28 pre-recorded sessions that will be released on the first day of the conference, these will be available to watch at your leisure and will be available until March 19, 2021. PLEASE NOTE: They are available longer than the 1-5 pm time on the schedule but we are not able to program them in like that!
  • ON DEMAND E-Poster Sessions: There will be 8 E-Poster sessions available to watch, each session is 15 minutes long and worth a quarter of a credit, in order to receive a full hour you will need to watch 4 poster sessions all the way through and complete and evaluation. These will be available as pre-recordings and will be available from the start of the conference until March 19, 2021
This means you have the opportunity for up to 19.0 CE credits at this years conference! (See ASHA AND AAA Brand Blocks below)

ON DEMAND SESSION: Exposure to Ototoxicants in the Workplace – Recent Developments Towards Prevention of Potential Hearing Disorders

Sign up or log in to save this to your schedule, view media, leave feedback and see who's attending!

Feedback form is now closed.
Noise remains the predominant cause of work-related hearing loss, but evidence demonstrates that certain common chemicals can also damage hearing. Chemicals identified as ototoxic include: solvents, metals, asphyxiants, carbon monoxide, organotins, polychlorinated biphenyls (PBCs), and certain pesticides. Reports from animal experiments demonstrate that chemicals can interact synergistically with noise or potentiate its effects. The interaction is modified by several factors, including the temporal distribution of the noise exposure. Some ototoxic chemicals can affect hearing even with low or no noise exposure. Evidence has prompted the proposal of new guidelines and standards on hearing loss prevention internationally. In 2018, the Occupational Safety and Health Administration and the National Institute for Occupational Safety and Health jointly published the Safety and Health Information Bulletin Preventing Hearing Loss Caused by Chemical (Ototoxicity) and Noise Exposure. Since 2019, the American Conference of Governmental Industrial Hygienists’ Threshold Limit Values® publication has included an ototoxicity notation to alert the occupational safety and health community about the potential hazard. In 2020, NHCA joined the International Ototoxicity Management Group, which will, now, include information on ototoxicants other than medications. This presentation will examine recent developments and suggest recommendations for preventing auditory effects of exposure to ototoxic chemicals.

Learning Objectives:
1. Participants will identify the classes of chemical ototoxicants that affect hearing.
2. Participants will determine factors that can affect risk of ototoxicity, including impulsive noise exposures
3. Evalaute chemical exposure solutions can reduce the risk of hearing loss.
