WEBINAR - ACGIH® Upper Limb Localized Fatigue TLV®


In 2016 ACGIH® published a new TLV®: Upper Limb Localized Fatigue. The purpose of the TLV® is to provide employers and health and safety professionals with guidance for preventing upper extremity musculoskeletal fatigue among workers who perform cyclical work for two or more hours per day. The TLV® is based on combinations of force, exertion time and frequency that have been found to be acceptable for repetitive work.  Exposure limits of job risk factors are presented that will allow most healthy workers to maintain their work capacity and normal performance for the duration of the workday without experiencing excessive, persistent fatigue. Deficits that occur during the workday should be reversibly resolved during the daily breaks from work, allowing for typical life activities beyond work. Excessive fatigue may be experienced as pain, decreased strength, localized discomfort, tremor or other symptoms or signs of reduced motor control. This webinar will present an introduction to localized fatigue, the scientific basis for the TLV®, methods of determining force patterns, application of the TLV® and several case studies that apply to the TLV®. At the conclusion of the presentation, there will be time for questions and comments.

What is an ACGIH® Webinar?

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. This ACGIH® webinar is 1 hour in duration and consists of a live presentation given via the Internet with an audio telephone link similar to that of a conference call.

Audio Option

ACGIH® is pleased to offer webinar attendees an audio option. U.S. and Canadian attendees can connect to the audio portion of the webinar via the toll-free audio telephone link or listen to the audio portion through an audio stream directly through their computer. Other international participants can listen via the audio stream without incurring additional telephone charges.*

*Connection from outside the U.S. and Canada will be via streaming audio only.


This webinar contains 1.0 hour of instruction and may be eligible for ABIH CM credit. See the ABIH website (www.abih.org) for CM credit criteria. This webinar may also qualify for BCSP recertification points for Certified Safety Professionals. Participants seeking confirmation of attendance for the webinar from ACGIH® must attend the live webinar or view the archive and submit a final exam and evaluation. Certificates of Completion will be issued in a timely manner after receipt and completion of these items.
