Flammability Toxicity Body Contact Reactivity Chronic Page 2 of 6 Section 3 - COMPOSITION / INFORMATION ON INGREDIENTS NAME CAS RN % a blend of clay inhibitive polymers 30-60 potassium acetate 127-08-2 10-<30 nonhazardous ingredients balance Section 4 - FIRST AID MEASURES SWALLOWED o If swallowed do NOT induce vomiting. o If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain open airway and prevent aspiration. o Observe the patient carefully. o Never give liquid to a person showing signs of being sleepy or with reduced awareness; becoming unconscious.

4 EYE o If this product comes in contact with the eyes: o Wash out immediately with fresh running water. o Ensure complete irrigation of the eye by keeping eyelids apart and away from eye and moving the eyelids by occasionally lifting the upper and lower lids. o Seek medical attention without delay; if pain persists or recurs seek medical attention. o Removal of contact lenses after an eye injury should only be undertaken by skilled personnel. SKIN o If skin or hair contact occurs: o Flush skin and hair with running water (and soap if available). Seek medical attention in event of irritation. INHALED o If fumes, aerosols or combustion products are inhaled remove from contaminated area.

5 O Other measures are usually unnecessary. NOTES TO PHYSICIAN For potassium intoxications: o Hyperkalaemia, in patients with abnormal renal function, results from reduced renal excretion following intoxication. o The presence of electrocardiographic evidence of hyperkalemia or serum potassium levels exceeding mE/L indicates a medical emergency requiring an intravenous line and constant cardiac monitoring. o The intravenous ingestion of 5-10 ml of 10% calcium gluconate, in adults, over a 2 minute period antagonises the cardiac and neuromuscular effects. The duration of action is approximately 1 hour. [Ellenhorn and Barceloux: Medical Toxicology].

6 Section 5 - FIRE FIGHTING MEASURES EXTINGUISHING MEDIA There is no restriction on the type of extinguisher which may be used. Use extinguishing media suitable for surrounding area. FIRE FIGHTING Alert Fire Brigade and tell them location and nature of hazard. Wear breathing apparatus plus protective gloves in the event of a fire. Prevent, by any means available, spillage from entering drains or water courses. Use firefighting procedures suitable for surrounding area. FIRE/EXPLOSION HAZARD Non combustible. Not considered to be a significant fire risk. Expansion or decomposition on heating may lead to violent rupture of containers.

7 Decomposes on heating and may produce toxic fumes of carbon monoxide (CO). Decomposes on heating and produces toxic fumes of: carbon dioxide (CO2), nitrogen oxides (NOx).

Section 8 - EXPOSURE CONTROLS / PERSONAL PROTECTION EXPOSURE CONTROLS The following materials had no OELs on our records potassium acetate: CAS:127- 08- 2 MATERIAL data AMC K-ION : Not available POTASSIUM ACETATE: It is the goal of the ACGIH (and other Agencies) to recommend TLVs (or their equivalent) for all substances for which there is evidence of health effects at airborne concentrations encountered in the workplace.

10 At this time no TLV has been established, even though this MATERIAL may produce adverse health effects (as evidenced in animal experiments or clinical experience). NOTE: The ACGIH occupational exposure standard for Particles Not Otherwise Specified ( ) does NOT apply. Sensory irritants are chemicals that produce temporary and undesirable side-effects on the eyes, nose or throat. Historically occupational exposure standards for these irritants have been based on observation of workers' responses to various airborne concentrations.
