Press Release


Cincinnati, Ohio — January 13, 2015 — ACGIH® will present ACGIH® TLV® for Heat Stress and Strain in the Context of Heat Stress Management on March 4, 2015 at the following times:

2:00 p.m. – 4:30 p.m. Eastern Time
1:00 p.m. – 3:30 p.m. Central Time
12:00 p.m. – 2:30 p.m. Mountain Time
11:00 a.m. – 1:30 p.m. Pacific Time

While the Heat Stress and Strain TLV® is designed for exposure assessment, it exists in the context of an integrated heat stress management program. This webinar will outline the components of a heat stress management program to illustrate how the TLV® can be used for exposure assessment and the development of controls. Special attention will be given to the three stages of exposure assessment (screening, WBGT-based TLV® and physiological monitoring) and approaches that can be taken at each stage. Because controls are designed to reduce risk, there is a natural interaction between control approaches and exposure assessment. Models to predict WBGT and other environmental parameters will be presented as alternatives to directly measuring WBGT during routine monitoring.

After participating in this webinar, attendees will be able to:

  • Articulate the rationale for the ACGIH® Heat Stress and Strain decision process
  • Describe the components of a heat stress management program
  • Apply the Heat Stress and Strain TLV® exposure limits and control measures
  • Discuss interactions of exposure limits and control measures
  • List some methods of WBGT estimation
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.
