 2 - Moderate Hazard
 3 - Serious Hazard
 4 - Severe Hazard

  Potential Health Effects
  Inhalation:  Dust irritating to respiratory tract.
  Ingestion:  May cause irritation to mouth, esophagus, and stomach. Large doses are harmful if swallowed.
  Skin Contact:  Causes slight irritation to the skin.
  Eye Contact:  Causes mild irritation to the eyes.
  Chronic Exposure:  Cancer hazard. Contains crystalline silica which can cause cancer and delayed lung injury (silicosis). Crystalline silica is listed by NTP as a known human carcinogen, and it is classified by IARC in Group 1: materials for which there is sufficient evidence in humans for carcinogenicity. 
  Aggravation of Pre-existing Conditions: No information found.

3. First Aid Measures

  Inhalation: Remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical attention.
  Ingestion: If swallowed, DO NOT induce vomiting. Get medical attention immediately. If victim is fully conscious, give a cupful of water. Never give anything by mouth to an unconscious person..
  Skin Contact: In case of contact, immediately flush skin with plenty of water. Remove contaminated clothing and shoes. Get medical attention.
  Eye Contact: In case of contact, immediately flush eyes with plenty of water for at least 15 minutes. Get medical attention.

4. Fire Fighting Measures
  Fire: This material is noncombustible.
