Wind speeds are slower at the ground level due to friction. As height increases so does the speed of the wind. Now imagine you are in a bucket truck, drilling into a creosote pole and the shavings are getting blown into your face. It’s not just windy; this is a debris storm and just one of the reasons to wear an arc and flame resistant Face Muffler. Another reason is that every few months we launch a cool new design on them with limited availability.
