A paper product made at the Smelter is proving highly successful in preventing lead dust from blowing off the site. The thin layers of papier mache which are constantly being sprayed over stock piles around the site are proving to be effective in minimising any possible movement by wind. The papier mache is in the form of a light spray and is made by mixing 50 kilograms of paper to 15,000 litres of water. 25,000 litres are made per day which when sprayed on the stock material, dries hard leaving a fine, white film on top. To help contain any on site lead dust, hessian wind breaks are also placed onto the fences at the boundary of the site.
