SKIN: Wash with soap and water. EYES: Rinse eyes with water for at least 15 minutes, lifting eye lid occasionally. See a Physician. INGESTION: Do not induce vomitting. Dilute by drinking milk or water. Never give anything by mouth to unconscious person. Keep victim warm and at rest. See a Physician. INHALATION: Remove from dusty area to fresh air.

Section VI Health Hazard Data
Route(s) of Exposure:	Inhalation?�	Skin?�	Ingestion?�
Health Hazards(Acute and Chronic) ACUTE: Irritation of the eyes, skin and mucous membranes. Repeated overexposure to very high levels of respirable crystalline silica for periods as short as six months have caused acute silicosis. CHRONIC: Fibrotic disease of the lungs (silicosis) and carcinogencity.
Carcinogenicity:	NTP?	IARC Monographs?�	OSHA Regulated?
Signs and Symptoms of Exposure SILICOSIS: Shortness of breath, cough, fever, weight loss and chest pain.
Medical Conditions Generally Aggravated by Exposure Excessive dust exposure may aggravate any existing respiratory disorders or diseases. Possible complications of alleriges resulting in irritation to skin, eyes and respiratory passage may occur from excessive exposure to dusts.
Emergency and First Aide Procedures

Section VII - Precautions for Safe Handling and Use
Steps to Be taken in Case Material is Released or Spilled Clean up for use or disposal. Dampen with a water mist to control dust (airborne dust) before removal. Do not use compressed air. If loaded on trucks, wet down material to prevent dusting during transport.
Waste Disposal Method Dispose of in a landfill or coal ash disposal pond. observe local, state and federal regulations. This material is not a RCRA hazardous waste.
Precautions to Be Taken in Handling and Storing Store in dry conditions. Minimize dust. Avoid creating dust.
Labeling WARNING: Normal safety precautions are advised when handling these materials. Dampen with a water mist to control airborne dust and use appropriate personal protective equipment to avoid inhalation and exposure to eyes, skin and mucus membranes. Excessive exposure to these materials may cause irritation of the eyes, skin and mucus membranes and chronic exposure could lead to fibrotic disease of the lungs. This product contains silica, which has been identified as a carcinogen. If contact is made, areas affected should be thoroughly flushed with water. Medical attention is advised in case of ingestion, inhalation or eye contact. A Material Safety Data Sheet is on file. Call 210-349-4069 and ask for the Safety Manager.

Section VIII - Control Measures
Respiratory Protection(Specify Type) None required under PEL. If PEL is exceeded, use MSHA/NIOSH TC-21C-XXX respirators.
Type of Ventilation Local Exhaust� Special Mechanical (General)� Other	If Special or Other specify: Use local exhaust during transfer to stay below PEL. Use mechanical ventilation for indoor work places as needed.
Protective Gloves Work gloves as needed
Eye Protection Recommend Safety goggles or safety glasses. Eye wash stations should be readily accessible.
Other Protective Clothing or Equipment As needed.
Work/Hygenic Practices Use good hygiene practices and observe above precautions.
