Exposure to silica particles present in dust from dry-mixed bagged products, cutting fixed concrete, or treating hardened concrete with high silica aggregates can harm the respiratory system. Prolonged inhalation of high levels of respirable crystalline silica, due to inadequate control measures or failure to use proper respiratory protection, may result in silicosis and an elevated risk of lung cancer. Consumption of small quantities of cement/water mixtures is unlikely to cause a significant reaction.
If the mixes are wet, while material is still in non-hardened (plastic) state, use suction system or mechanical shovel. The product can be made into slurries by adding water, but it will subsequently set as a hard material. Disposal: -None hazardous. Nonetheless, disposing should comply with local authority/regulations requirements. -When the clean-up is in operation, keep children away. Environmental Precautions: -Do not allow the product to enter drains, sewers, or water courses. Further spillage if possible. First Aid for Wet or Dry (Dust) concrete/mortar/screed: -To prevent eye contact, wash immediately with a large amount of clean water.
Immediately seek medical attention from the first aider or health nurse if needed. If you have come into contact with the substance, wash your skin several times with clean water (use soap if your hands are dry) and remove and thoroughly wash any clothing. Seek medical advice if you experience irritation, pain, or any other skin conditions. In case of ingestion, do not induce vomiting; rinse your mouth and drink plenty of water. Seek medical advice if a large amount has been swallowed. If irritation occurs from inhalation, move to an area with fresh air and seek medical advice if your nose or airways become inflamed. Make sure to adhere to proper storage and handling requirements.
Storage: Dry mix concrete and mortar bags should be stacked in a safe and stable manner, away from any moisture.
Handling: Wet Concrete, Mortar and Screed: Avoid skin and eye contact. Bagged dry-mix concrete and mortar: When handling bags take care when lifting, due regard should be paid to the risks outlined in the Manual Handling Operations Regulations 1992. Some bags may have a small amount of cement on the outer surface. Appropriate personal protective clothing should therefore be used whilst handling.
Fire: Not flammable and will not facilitate combustion with other material.
