Skin and ingestion exposure to silica is generally not thought to be a concern in and of itself however, the re-entrainment of silica back into the air creates an airborne hazard that warrants attention. As a result, good hygiene practices, gloves, body protection (coveralls), and proper hand washing is required.
prone to gas defects when using the local sand. The local sand with a silica content of 98 per cent after washing appears to be cleaner than the imported sand silica content of 97( per cent). This makes the local sand slightly more refractory than the imported sand. This is also evident the sintering test results of the from as-received sands.
