Mar Mound Clay is a natural occurring clay mineral made up of red/brown clay particles and contains up to 40% crystalline silica. It is classified for specific target organ toxicity (single exposure, Category 3) due to potential respiratory irritation and includes respirable crystalline silica identified as a carcinogen by NTP and IARC. At dust levels below recommended exposure limits, adverse health effects are not expected, and the product is non-flammable, stable under normal conditions and non-hazardous for air, sea and road freight. Recommended precautions focus on minimizing dust exposure and following appropriate disposal regulations.
Key Points
- Natural occurring clay mineral with red/brown clay particles containing up to 40% crystalline silica.
- Contains crystalline silica known to cause silicosis and listed as a carcinogen by NTP and IARC; may cause respiratory irritation.
- As formulated, not expected to form appreciable respirable crystalline silica dust, and exposure during normal use is indicated to be well below OSHA Permissible Exposure Limit (PEL) and ACGIH Threshold Limit Value (TLV).
- Non-flammable, stable under normal conditions, non-hazardous for air, sea and road freight, and should be disposed of in accordance with applicable federal, state and local regulations.
