Personal Protective Clothing
- Air cooled or water cooled garments.
- Air supplied hoods and suits can be adapted to provide cooled air.
- Wetted head bands and other overgarments.
Measurement of Heat Stress
Heat stress is measured using the Wet Bulb Globe Thermometer (WBGT). The ACGIH has TLVs to assist in interpreting these measurements that establish a work rest routine appropriate for the type of work being done.
- Identify the work type
- Determine current work/rest regimen
- Collect WBGT data
- Use WBGT index to evaluate
- Make necessary adjustments
- Identify workers at risk
- Monitor environment and make adjustments
- Provide PPE, water, rest and first aid as required
In a changing work environment, the best approach is good employee education and management controls.
