When washing mortar waste and it dries, the dried particles can be a source of dust that may contain silica, depending on the specific materials used in the mortar. Breathing in silica dust can be harmful to your respiratory health, potentially leading to conditions such as silicosis or other respiratory issues.
To minimize risks:
- Wear a Mask: Use an N95 respirator or a mask designed to filter out dust when working with or around dried mortar waste.
- Avoid Disturbing the Dust: Try to keep the area damp when you are cleaning up to reduce the amount of dust generated.
- Clean Up Thoroughly: If the mortar has dried, consider using a damp cloth or sprayer to moisten the surface before sweeping or vacuuming, which can help minimize dust.
If you have concerns about potential exposure or pre-existing respiratory conditions, it’s best to consult with a health professional. Always prioritize safety when handling construction materials.
