Thomas E. Bernard, PhD, current member and past chair of the ACGIH® Threshold Limit Values for Physical Agents (TLV®-PA) Committee, reflects on the many issues surrounding the management of occupational heat stress. First, WBGT-based occupational exposure limits are intended to flag levels of heat stress that cannot be sustained by some people during a nominal working day. There are two protective mechanisms inherent in this approach that will be discussed. Second, OSHA’s 10 Elements of Heat Stress Management provides a framework to discuss the management of heat stress. Third, while schedules for acclimatization and work/recovery cycles are available, making these schedules work for occupational heat stress is not always obvious. Finally, no reasonable heat stress management program will be 100% protective against exertional heat stroke, as such, other measures must be in place to identify and respond when heat stroke occurs. This webinar will outline the rationale for the WBGT-based occupational exposure limits. It will discuss OSHA’s 10 Elements of Heat Stress Management. Special attention will be given to operationalizing acclimatization to occupational exposures and work/recovery cycles. Recognition and management of risk for exertional heat stroke will be discussed, including identification of personal risk factors and emergency response best practices.

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

  • Articulate the underlying rationale for the WBGT-based occupational exposure limits.
  • Review a heat stress management program in the context of OSHA’s 10 Elements.
  • Recommend a heat stress acclimatization program appropriate to a site’s OHS program.
  • Recommend work and recovery cycles appropriate to a site’s OHS program.
  • Prepare a site’s heat stroke mitigation plan.

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.
