Abstract In this day and age, employee health safety is an extremely important issue for companies. Along with maximising profits, companies such as Sims Metal Management want to provide the best working conditions possible for their employees and minimise the risks of injury or future health concerns. Companies must do what is reasonable and practicable to ensure this. Currently in the non-ferrous recovery plant, the dust levels are sometimes too high. This causes some issues, employees must wear uncomfortable dust masks all day and causes further discomforts. It settles on machinery and on the ground. Over time this dust builds up requiring extensive cleaning and production must be stopped. Dust also increase maintenance costs and reduces the life of machinery.

To combat the dust the following were completed. A high pressure water system was used to slightly dampen stored material and suppress dust plumes when this material is unloaded from the bucket of a front end loader. A bag house dust suction system was installed to remove as much dust as possible without overloading the suction system.

A vibratory screener was modified to filter out the finer material and remove as much dirt as possible before it travelled further down the plant spilling and vibratory feeds which usually cause dust particles to become airborne. Wider conveyor belts and additional skirting systems and belt scrapers were installed to reduce the spillage.

The amount of car tires entering the plant was also reduced by rearranging the magnet setup to decrease load on metal sorters and allow an increase in the processing rates in the plant.
