CAOHC & NIOSH Certification by e3 Occupational Health


If you are administering hearing or spirometry tests as part of your occupational health and safety program, it’s important that you and your colleagues stay up to date with certifications and training. While not mandated, OSHA strongly recommends that everyone administering a hearing test within a hearing conservation program is CAOHC certified. This ensures that your entire staff has been consistently trained and that testing results are consistent throughout your program. And for spirometry, depending upon your environment or employee exposure, OSHA regulations do require that individuals who administer spirometry tests need to successfully complete a NIOSH-approved spirometry training course. NIOSH-approved spirometry training courses are also recommended for training healthcare professionals to gain the skills and knowledge needed to collect accurate spirometry results.

e3 Occupational Health Solutions and our partners facilitate more than 70 NIOSH & CAOHC certification and re-certification courses throughout the year. These courses are available in many locations to make it more convenient and affordable for you and your staff to attend. Please see below for some helpful information about the courses.

CAOHC Approved Hearing Testing for Occupational Hearing Conservation

According to the Occupational Safety & Health Administration (OSHA) 29 Code of Federal Regulation 1910.95(g)(3):

"Audiometric tests shall be performed by a licensed or certified audiologist, otolaryngologist, or other physician or by a technician who is certified by the Council for Accreditation in Occupational Hearing Conservation or who has satisfactorily demonstrated competence in administering audiometric examinations, obtaining valid audiograms and properly using, maintaining and checking calibration and proper functioning of the audiometers being used."

Although an audiometric testing program must be supervised by a physician or Audiologist, a certified occupational hearing conservationist (COHC) is directly involved with noise-exposed workers and their activities. COHCs typically perform pure tone air conduction audiometric testing, fit hearing protection, provide education, and enforce hearing conservation program (HCP) compliance. 

To become a Certified Occupational Hearing Conservationist (COHC), you need to complete the Council for Accreditation in Occupational Hearing Conservation (CAOHC)-approved, 20-hour certification course and pass the accompanying exam.

Our training courses meet the requirements of the Council for Accreditation in Occupation Hearing Conservation (CAOHC). Upon successful completion of the course participants are eligible for certification through CAOHC.
