SECTION IV - PHYSICAL HAZARDS (REACTIVITY DATA):



This mixture has not been tested as a whole.

Threshold Limit Value: ND



Effects of Overexposure:

Overexposure by contact may cause mild to severe irritation of burns of skin, eyes and

mucos membranes. Splashes in the eye may cause damage with ulceration of the cornea,

prolonged contact may cause irreversible eye damage including blindness.



Ingestion (Swallowing):

Miniscule amount swallowed during proper use should not cause injury. Ingestion of

large amount may cause irritation of the upper GI tract with pain and distention of the

stomach and esophagus due to the liberation of oxygen.



Emergency and First Aid Procedures:

Eyes - Immediately flush with plenty of water for at least 15 minutes. Seek medical

attention.

Skin - Immediately flush with plenty of water for at least 15 minutes.

Inhalation - Small amount of product will not emit concentrated amount of vapors. In

case of breathing difficulty or shortness of breath secondary to ingestion of large amount

of product, immediately move to a well ventilated area. If not breathing, give artificial

respiration.

Ingestion - If swallowed in large amounts, do not induce vomiting. Give large amounts of

water. Seek medical attention if abdominal discomfort persists.



SECTION V - REACTIVITY DATA

Stability: Unstable with heat of contamination causing the liberation of oxygen



Conditions to avoid: Contamination with incompatible materials including rust, dust, or

dirt. Overexposure to heat or light.

Incompatibility (Materials to avoid): Most flammables as well as cyanides, nitric acid and

most oxidizing and reducing agents.



Hazardous Decomposition: Contamination or heat may cause self accelerated

decomposition.



Hazardous Polymerization: Will not occur.



SECTION VI - SPILL OR DISPOSAL PROCEDURES



Steps to be taken in case material is released or spilled:

For small spills, collect material and dispose per federal, state and local regulations. For

larger spills (CERLA reportable quantity is 100lbs for unlisted hazardous waste), isolate

area which may present a slip hazard. Sweep or collect material and dispose per federal,
