Respirable crystalline silica班前安全会讲稿

它是什么

Fine silica dust from cutting, drilling, grinding or crushing stone, concrete, brick and tile that can cause silicosis and other lung disease.

要检查的控制措施，最有效的排在前面

1. Do not use banned engineered stone products, and choose lower-silica materials or pre-cut components where possible.
2. Use water suppression or on-tool extraction connected to a vacuum rated for hazardous dust when cutting, grinding or drilling.
3. Clean up with wet methods or a vacuum rated for hazardous dust, and never dry sweep or use compressed air.
4. Arrange air monitoring to confirm exposures stay below the workplace exposure standard for respirable crystalline silica.
5. Provide health monitoring for workers at significant risk from silica exposure, as WHS laws require.
6. Wear fit-tested respiratory protection suited to the task, and be clean-shaven where a tight-fitting respirator is used.
