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?

Critical Messages1. Dust has become a very serious problem
in the construction industry2. The broom is one of the causes for this
problem3. The solutions so far have not been very
effective or practical4. The shear simplicity of improving the
broom is good

Costs•£12 to produce▫Substantially cheaper than other solutions▫Very cheap to repair and maintain▫Hollow polyethene terephthalate – design
storage container for water. ▫Nylon over polypropylene bristles. (Nylon
priced at £2.65 per unit). ▫Injection moulding 200 brooms per hour.

Costs - continued•Wage costs £0.17 per unit,
taking into account time and level of skill combined with legal requirements also followed.
•£0.45 per unit – Injection moulding. Quality and quantity ensured.
