Why Should You Switch To Silica Free?

To protect workers. Workers who inhale these very small crystalline silica particles are at increased risk of developing serious silica-related diseases, including:

  • Silicosis, an incurable lung disease that can lead to disability and death
  • Lung cancer
  • Chronic obstructive pulmonary disease (COPD)
  • Kidney disease
