| Abstract |
The working environment in a casting knockout operation was studied in order to improve the safety and health of workers. The results were computer processed and a mathematical model was developed. By way of improvement it was suggested that the additives ammonium sulfate and sodium sulfite be used, which improve the strength of water-glass (sodium silicate) mixtures and facilitate knocking out. This measure decreases the physical work load of the operation and helps to bring down dust levels in the workplace air. |
