Biological Monitoring in Occupational Exposure Assessment

Earn 2 Education Contact Hours

This is an asynchronous online course on how to use biological monitoring to assess chemical exposures. Biomonitoring can help in exposure assessment of specific chemicals and characterization of exposure pathways. Biomonitoring is especially useful when chemicals enter the body through inhalation and skin. Recall that traditional industrial hygiene air monitoring can only assess airborne exposures. Biomonitoring may be interpreted at group or individual levels in conjunction with ACGIH Biological Exposure Indices (BEI) values.

Subscriber Price: $120
Non-Subscriber Price: $150


Certificate in Noise and Hearing Loss Prevention

Earn 7 Education Contact Hours

You may know that noise exposure is a ubiquitous workplace hazard in the US and globally, and that noise-induced hearing loss is one of the most common occupational diseases. However, did you know that occupational noise has also been linked to high blood pressure and injuries? Or that the Occupational Safety and Health Administration’s limit for noise is not very protective against noise-induced hearing loss? This certificate course explores the basics of noise, auditory and non-auditory health impacts of noise, noise measurement instrumentation and methods, relevant exposure limits and guidelines (including the ACGIH® TLVs® for Audible Sound, Infrasound, and Ultrasound), hearing loss prevention programs, noise controls, and hearing protection devices. Learners can also choose to learn about ototoxic exposures (that is, chemical agents that can harm hearing even in the absence of noise), hearing protector fit testing, and community noise assessment. Practical and real-world examples are included throughout the course to reinforce key concepts. Technical readings are tied to each topic to allow learners to explore concepts in greater detail.

ACGIH is dedicated to providing quality, scientific, educational events. One method of doing this is to offer distance-learning webinars. A webinar, short for Web-based seminar, is a presentation, lecture, or seminar that is transmitted over the Internet. A key feature of a webinar is its interactive elements — the ability to give, receive and discuss information. Webinars are as effective as on-site presentations without the travel expense. An ACGIH webinar can be of various durations and consists of a live presentation given via the Internet with an audio telephone link similar to that of a conference call.

Each webinar may qualify for ABIH CM credit and BSCP Continuance of Certification points. To receive confirmation of attendance, attendees must view the webinar and submit a final exam and evaluation. Each webinar includes one test. Additional tests can be purchased for other attendees.
