Thermal Environment Assessment Services in Australia

Thermal environment assessment uses Wet Bulb Globe Temperature (WBGT) instrumentation to evaluate heat stress risk in outdoor, process, and confined space work environments. Measurements capture air temperature, radiant heat, humidity, and air movement to calculate a composite thermal index.

Results are compared against ISO 7243 reference values and metabolic rate estimates for specific tasks. Cold stress assessment evaluates wind chill, contact temperature, and core body temperature risk for workers in refrigerated environments, cold rooms, and outdoor winter conditions.

OHConnect thermal assessment practitioners provide work-rest cycle recommendations, hydration protocols, and engineering control guidance based on quantitative thermal data.

When You Need This Service

  • Workers perform moderate to heavy physical tasks in ambient temperatures above 30 degrees C
  • Radiant heat sources such as furnaces, kilns, or molten metal are present
  • Outdoor workers face extreme heat during summer months
  • Cold room, freezer, or refrigerated warehouse workers report discomfort
  • Heat-related illness incidents have occurred at the workplace
  • Work-rest schedules need evidence-based justification
