Limited Agreement Between Perceptual and Physiological Heat Strain at Initial Stay Times for Continuous Work in the Heat Before Heat Alleviation Controls

open access: yesAmerican Journal of Industrial Medicine, EarlyView.
ABSTRACT Introduction Accurate assessment of heat strain at initial stay time (IST; core temperature 38.0°C or Δ1.0°C above resting), when heat mitigation decisions are required, is critical for managing occupational heat exposure. We evaluated the relationship and agreement between physiological (Physiological Strain Index [PSI] and adaptive PSI [aPSI]

Timing of Work‐Rest Implementation Influences Worker Productivity Under Heat Stress: Evidence for Initial Stay Time‐Based Scheduling

open access: yesAmerican Journal of Industrial Medicine, EarlyView.
ABSTRACT Introduction Work‐rest allocations recommended by the American Conference of Governmental Industrial Hygienists (ACGIH) limit heat strain and are typically implemented from the onset of work. Whether delaying implementation until after the initial stay time (IST; the duration of continuous work before core temperature reaches 38.0°C) improves ...
