Washed builders' sand is generally considered to be safer for your lungs compared to unwashed or "raw" sand, as washing helps to remove fine particles, dust, and contaminants that could be inhaled. However, even washed sand can produce dust when disturbed, which can still pose respiratory risks if inhaled in significant amounts.
When handling any type of sand, it's important to take precautions:
-
Use a Dust Mask or Respirator: If you are working in an environment where dust is produced, wearing a mask can help protect your lungs.
-
Ensure Proper Ventilation: Make sure the area is well-ventilated to minimize dust accumulation.
-
Wet the Sand: Dampening the sand can help reduce dust emissions, but be cautious not to use too much water, which can make it difficult to work with.
-
Avoid Prolonged Exposure: Limiting the amount of time you spend in dusty environments can also help reduce respiratory risks.
If you're concerned about health risks, particularly with prolonged exposure to any kind of dust, consulting with a health professional is a good idea.
