PROTOTYPE HEAT STRESS FORECASTING SYSTEM FOR THE INITIAL SCREENING OF RISKS AMONG OUTDOOR WORKERS

Experimental activity for use by workers, employers occupational safety and management professionals.

 

This section shows heat stress risk forecast maps for some non-acclimatized worker profiles developed on the basis of an indicator used in the occupational sector and selected within the project (Wet Bulb Globe Temperature, WBGT).

The maps show three-day heat stress risk forecast, at four time intervals during the day: 8:00, 12:00, 16:00 and 20:00 CET.

 

THE INFORMATION RELATES TO A HEALTHY WORKER, NOT ACCLIMATISED TO HEAT, EXPOSED TO DIRECT SUN OR SHADE AND ENGAGED IN INTENSE OR MODERATE OUTDOOR PHYSICAL ACTIVITY.

Moderate physical activity includes:

 

  • Upper limb activities (hammering nails, filing)
  • Driving off-road trucks, tractors or construction machinery
  • Working with the upper body (pneumatic hammer work, tractor assembly, plastering, intermittent handling of moderately heavy material, weeding, hoeing, picking fruit or vegetables)
  • Pushing or pulling light carts or wheelbarrows
  • Walking at a moderate speed (3.5 and 5.5 km/h)
  • Laying bricks
  • Assembling vehicles

Intense physical activity includes:

 

  • Physically intensive upper body activity; carrying heavy material
  • Work requiring the use of axes or shovels for shoveling or digging at an intense pace
  • Working with a hammer
  • Sawing, planing or chiselling hard wood
  • Hand mowing, digging
  • Walking at a speed between 5.5 and 7.0 km/h
  • Pushing or pulling wheelbarrows and barrows with heavy loads
  • Arranging concrete blocks
  • Repeatedly climbing steps or ladders

In consideration of the typical conditions of the autumn-winter period, the personalized heat risk forecasts for workers are currently suspended and will resume in the
spring 2022.
