2. The Brief Design a hand held sweeping device that will not only sweep up construction debris but will also provide an effective method to provide wetting/dampening of airborne dust & debris. Dust: Occupational Health Hazard ▫ Very Latent effects ▫ Silicosis epidemic in 20 years?

4. Critical Messages 1.Dust has become a very serious problem in the construction industry 2.The broom is one of the causes for this problem 3.The solutions so far have not been very effective or practical 4.The shear simplicity of improving the broom is good
