In addition, where there is a reasonable risk of workers developing silicosis, health surveillance is required. Guidance is available in Health surveillance for those exposed to respirable crystalline silica RCS G404. Case studies.
Use exclusion zones so that other workers are not exposed. The zone will be based of your air monitoring, and the bigger the zone is, the better. Develop a respirable crystalline silica dust control plan.
Washington Employees who work with stone countertops are at risk of crystalline silica exposure, and employers should take steps to protect them, OSHA and NIOSH stated Feb. 18 in a joint hazard alert. Exposure to even a small amount of silica can lead to silicosis an incurable and debilitating lung disease, lung cancer or other diseases, the agencies warn.

Introduction Artificial stone is an increasingly popular material used to fabricate kitchen and bathroom benchtops. Cutting and grinding artificial stone is associated with generation of very high levels of respirable crystalline silica, and the frequency of cases of severe silicosis associated with this exposure is rapidly increasing.
Employers must provide health monitoring if exposure to crystalline silica is likely to have an adverse effect on employees health. Due to the high silica content of engineered stone, it is recommended that employers provide health monitoring to all employees who work in the vicinity of engineered stone processing work.

With ores of higher gold content i.e., greater than 20 grams of gold per ton of ore, cyanidation is accomplished by vat leaching, which involves holding a slurry of ore and solvent for several hours in large tanks equipped with agitators. For extracting gold from low-grade ores, heap leaching is practiced.
