SECTION VI - HEALTH HAZARD DATA

Route(s) of Entry:     Inhalation? Yes                        Skin? No            Ingestion? No



Health Hazards (Acute and Chronic): Cement when combined with body moisture and wet cement, especially as

an ingredient in plastic (unhardened) concrete, can dry the skin and cause alkali burn. Cement dust can irritate the

eyes and respiratory system. Chronic: Cement dust can cause inflammation of the lining tissue of the interior of the

nose and inflammation of the cornea. Hypersensitive individuals may develop an allergic dermatitis. (Cement can

contain traces of hexavelent chromium.) Alkaline nature of Portland cement may cause skin irritation.



Carcinogenicity: NTP? Silica dust is probable carcinogen from inhalation

IARC Monographs? Silica dust may be carcinogen if inhaled. Volume 68

OSHA Regulated? Not Regulated



Signs and Symptoms of Exposure: Skin irritation and mucous membrane irritation.



Medical Conditions Generally Aggravated by Exposure: Freshly mixed concrete grout or mortar may cause skin

injury. Avoid contact with skin and wash exposed areas promptly with water.



Emergency and First Aid Procedures: If powder gets into eyes, rinse immediately and repeatedly with water and

get prompt medical attention.



SECTION VII - PRECAUTIONS FOR SAFE HANDLING AND USE

Steps to Be Taken in Case Material Is Released or Spilled: Scoop up to collection containers.



Waste Disposal Method: Mix with water.



Precautions to Be Taken in Handling and Storing: Keep containers closed. Protect from moisture.



Other Precautions: Avoid breathing dust.



SECTION VIII - CONTROL MEASURES

Respiratory Protection: NIOSH approved organic respirator in confined areas.



Ventilation: Mechanical (General) Good general ventilation.
