What is the recommended temperature for wetting asbestos material during removal?

The recommended temperature for wetting asbestos material during removal is at or near room temperature to avoid freezing. This approach is important because using water that is too cold, especially below freezing, can create ice or frost, which can hinder the effectiveness of the wetting process. Proper wetting is crucial when handling asbestos as it helps to minimize the release of airborne fibers, thereby reducing the risk of inhalation and exposure.

When water is used to wet asbestos, it clings to the fibers, forming a barrier that keeps the fibers down, preventing them from becoming airborne during handling or removal. If the water is too hot, there is a risk of rapid evaporation, which can also lead to fiber release. Therefore, aiming for room temperature ensures that the water remains effective for wetting without adverse effects from extreme temperatures.
