If inhaled
Fresh air, rest. Refer for medical attention.
Following skin contact
Rinse skin with plenty of water or shower.
Following eye contact
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Following ingestion
Rinse mouth. Give one or two glasses of water to drink.

Absorption, Distribution and Excretion
If ingested in large amounts nausea, vomiting and diarrhea are probable. Thought to be hydrolyzed to (ortho)phosphates before absorption. If appreciable amounts of the intact polymer are absorbed from the alimentary tract, hypocalcemic tetany may be a danger due to the binding (chelation) of ionized calcium. Hypocalcemic tetany apparently occurred in one ingestion episode. Tripolyphosphate
In case of fire in the surroundings, use appropriate extinguishing media.
Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.
In case of fire in the surroundings, use appropriate extinguishing media.
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Sweep spilled substance into covered containers. Carefully collect remainder. Then store and dispose of according to local regulations.

Product
The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.
Contaminated packaging
Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
