FIRE AND EXPLOSION DATA:

	Flash Point: Non-flammable
	Method Used:
	Flammable Limits in Air % by Volume:
	Auto-Ignition Temperature:
	Extinguisher Media: Use water spray to keep fire-exposed containers cool
	Special Fire Fighting Procedures: Wear protective clothing and positive pressure self-contained breathing apparatus
	Unusual Fire & Explosion Hazards: Phosphoric acid can react with metals to liberate hydrogen, a flammable gas. Combustion by-products include oxides of phosphorus

PHYSICAL HAZARDS (REACTIVITY DATA):

	Stability: Stable
	Conditions to Avoid: None
	Incompatibility (Materials to Avoid): Avoid contact with materials such as sulfides and sulfites which could release toxic gases. Avoid strong alkalies because high heat of reaction can generate steam. Avoid most metals because phosphoric acid can react to liberate hydrogen, a flammable gas
	Hazardous Decomposition Products: Toxic gases, steam, hydrogen (flammable gas), and oxides of phosphorus
	Hazardous Polymerization: May Occur _____ Will Not Occur __X__

HEALTH HAZARDS:

	Acute: Corrosive material. Causes eye and skin burns. May not produce an immediate burning sensation upon skin contact, delaying awareness that contact has occurred
	Chronic:
	Threshold Limit Value:
	Signs and Symptoms of Exposure:
	Medical Conditions Generally Aggravated by Exposure:
	Chemical Listed as Carcinogen or Potential Carcinogen:
	Emergency & First Aid Procedures:
	Routes of Entry:
	Inhalation: None expected under normal conditions of use of this product. However, if inhaled as a mist or if the material is vaporized; it can be irritating to the respiratory tract. Remove person to fresh air. Seek medical attention if symptoms persist
	Eyes: Corrosive. May cause burns or irritation. Immediately flush with plenty of water for 15 minutes. Get medical attention
	Skin: Corrosive. May cause burns or irritation. May not produce an immediate burning sensation, delaying awareness that contact has occurred. Immediately flush with plenty of water for 15 minutes while removing contaminated clothing. Get medical attention. Wash clothing before reuse
	Ingestion: Corrosive. May cause burns or irritation to the mouth, throat or gastrointestinal tract. Slightly toxic. Dilute with water or milk. Do not induce vomiting. Get medical attention

SPECIAL PRECAUTIONS AND SPILL / LEAK PROCEDURES:

	Precautions to be taken in Handling and Storage: Store tightly closed in cool, dry well-ventilated location away from heat sources and out of direct sunlight. Separate from alkalies and most metals
	Other Precautions: Wash thoroughly after handling. Use with adequate ventilation. Keep container closed. Empty container retains vapor and product residue; observe all safeguards
	Steps to be taken in case material is released or spilled: Wear gloves and chemical splash goggles. For small quantities (as in this product): absorb spill with dry paper towels. Place all material in covered chemical waste container for disposal. Flush spill area with water. Follow all local, state, and federal regulations when disposing.

SPECIAL PROTECTION INFORMATION / CONTROL MEASURES:

	Respiratory Protection: Under normal conditions of use of this product, the usual surgical masks worn by dental staff are adequate. If used in vivo, a high-speed evacuation tip should be used to protect patient. When airborne limits are exceeded, a NIOSH-approved respirator with full facepiece is recommended
	Ventilation: No special ventilation required under normal conditions of use of this product. For larger quantities, adequate ventilation to keep TLV below 3mg/m3 . Local mechanical exhaust ventilation recommended
	Local Exhaust:
	Mechanical:
	Special:
	Other:
	Protective Gloves: Use chemically resistant gloves
	Eye Protection: Wear chemical splash goggles/glasses
	Other Protective Clothing or Equipment: Wear long sleeves, apron or lab coat over clothing, to protect skin. If used in vivo, use rubber dam around tooth to be etched and high-speed evacuator tip or other protective devices for patient. Mask all surrounding tissue. Emergency eye wash fountain should be available
	Work / Hygienic Practices: Routine
