Potential Health Effects
Primary Entry Routes: Inhalation, ingestion, skin and eye contact.
Target Organs: Eyes, skin, respiratory tract.
Acute Effects
Inhalation: May cause gastrointestinal irritation.
Eye: Contact with eyes may cause severe irritation, and possible eye burns.
Skin: May cause skin irritation.
Ingestion: May cause gastrointestinal irritation if consumed in extremely large quantity.
Carcinogenicity: IARC, NTP, and OSHA do not list Acesulfame k as a carcinogen.
Medical Conditions Aggravated by Long-Term Exposure:
Chronic Effects: None known

Inhalation: Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid if cough or other symptoms appear.
Eye Contact: Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower lids. Get medical aid immediately.
Skin Contact: Immediately flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Get medical aid if irritation develops or persists.
Ingestion: If victim is conscious and alert, give 2-4 cupfuls of milk or water. Get medical aid.
After first aid, get appropriate in-plant, paramedic, or community medical support.
Note to Physicians: Treat symptomatically and supportively.

Flash Point: ?? °F (?? °C)
Flash Point Method: CC?, OC?, COC?
Burning Rate:
Autoignition Temperature: ?? °F (?? °C)
LEL: ??% v/v
UEL: ??% v/v
Flammability Classification: Solid which exhibits difficult combustion or is difficult to ignite. 
Extinguishing Media: Water spray or fog. Foam. Dry chemical powder. BCF  (where regulations permit).  Carbon dioxide.
Unusual Fire or Explosion Hazards: Avoid generating dust, particularly clouds of dust in a confined or unventilated space, as dust may form an explosive mixture with air and any source of ignition, e.g., flame or spark, will cause fire or explosion.
Hazardous Combustion Products:  
Fire-Fighting Instructions:  Do not release runoff from fire control methods to sewers or waterways.
Fire-Fighting Equipment: Because fire may produce toxic thermal decomposition products, wear a self-contained breathing apparatus (SCBA) with a full face-piece operated in pressure-demand or positive-pressure mode.

Spill /Leak Procedures: Eliminate all ignition sources. Ventilate area.
Small Spills:  Vacuum or sweep up material and place into a suitable disposal container. Clean up spills immediately, observing precautions in the Protective Equipment section.
Large Spills
Containment: For large spills, dike far ahead of spill for later disposal. Do not release into sewers or waterways.
Cleanup: Avoid generating dusty conditions. Provide ventilation.
Regulatory Requirements: Follow applicable OSHA regulations (29 CFR 1910.120).

Handling Precautions: Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Use with adequate ventilation. Avoid contact with eyes, skin, and clothing. Keep container tightly closed. Avoid ingestion and inhalation.
Storage Requirements: Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances.

Engineering Controls:
Ventilation: Provide general or local exhaust ventilation systems to maintain airborne concentrations below OSHA PELs (Sec. 2). Local exhaust ventilation is preferred because it prevents contaminant dispersion into the work area by controlling it at its source.
Administrative Controls:
Respiratory Protection: Seek professional advice prior to respirator selection and use. Follow OSHA respirator regulations (29 CFR 1910.134) and, if necessary, wear a MSHA/NIOSH-approved respirator. Select respirator based on its suitability to provide adequate worker protection for given working conditions, level of airborne contamination, and presence of sufficient oxygen. For emergency or nonroutine operations (cleaning spills, reactor vessels, or storage tanks), wear an SCBA. Warning! Air-purifying respirators do not protect workers in oxygen-deficient atmospheres. If respirators are used, OSHA requires a written respiratory protection program that includes at least: medical certification, training, fit-testing, periodic environmental monitoring, maintenance, inspection, cleaning, and convenient, sanitary storage areas.
Protective Clothing/Equipment: Wear chemically protective gloves, boots, aprons, and gauntlets to prevent prolonged or repeated skin contact. Wear protective eyeglasses or chemical safety goggles, per OSHA eye- and face-protection regulations (29 CFR 1910.133). Contact lenses are not eye protective devices. Appropriate eye protection must be worn instead of, or in conjunction with contact lenses.
Safety Stations: Make emergency eyewash stations, safety/quick-drench showers, and washing facilities available in work area.
Contaminated Equipment: Separate contaminated work clothes from street clothes. Launder before reuse. Remove this material from your shoes and clean personal protective equipment.
Comments: Never eat, drink, or smoke in work areas. Practice good personal hygiene after using this material, especially before eating, drinking, smoking, using the toilet, or applying cosmetics.

Stability:  Acesulfame K is stable at normal room temperature in closed containers under normal storage and handling conditions. Anhydrous citric acid readily absorbs moisture from air.
Polymerization: Hazardous polymerization cannot occur.
Chemical Incompatibilities:
Conditions to Avoid: Dispersing powder in the air, contact with incompatibles, and exposure to heat and ignition sources.
Hazardous Decomposition Products: Thermal oxidative decomposition of citric acid can produce oxides of carbon, nitrogen and sulfur.
