recommended use instructions are followed.

4. FIRST AID MEASURES

General

Likely Routes of Exposure: Skin contact

Eye Contact

Immediately flush with plenty of water for at least 15 minutes. Get medical attention. Remove
material from eyes, skin and clothing.

Skin contact

Immediate first aid is not likely to be required. However, this material can be removed with water.
Wash heavily contaminated clothing before reuse.

Inhalation

Immediate first aid is not likely to be required. However, if symptoms occur, remove to fresh air.

Ingestion

Immediate first aid is not likely to be required. A physician or Poison Control Center can be
contacted for advice.

5. FIRE FIGHTING MEASURES

Extinguishing media

Not combustible. No special requirement.

Unsuitable extinguishable media

Not combustible. No special requirement.

Exposure hazards

None known.

Protective equipment

As a general precaution, firefighters & others exposed, wear self-contained breathing apparatus.

6. ACCIDENTAL RELEASE MEASURES

Personal precautions

Avoid unnecessary exposure and remove all material from eyes, skin and clothing.

Environmental precautions
ICL Performance Products LP Material Safety Data Sheet
Material: TETRAPOTASSIUM PYROPHOSPHATE 60% SOLUTION Page 3 of 6
Reference No.: AST10059 May 1, 2006
Small quantities: Avoid discharge into the environment.
Large quantities: Avoid discharge into the environment.

Method for cleaning up

Contain large spills with dikes and transfer the material to appropriate containers for reclamation
or disposal. Absorb remaining material or small spills with a suitable absorbent and then place in
a corrosion resistant chemical waste container. Do not allow spillage into sewers, streams or
storm conduits.

Refer to Section 13 for disposal information and Sections 14 and 15 for reportable quantity
information.

7. HANDLING AND STORAGE

Handling:

Avoid contact with eyes. Keep container closed.
Wash thoroughly after handling. Use only with adequate ventilation.

Emptied container retains vapor and product residue. Observe all labeled safeguards until
container is cleaned, reconditioned or destroyed.

Engineering measures

Provide natural or mechanical ventilation to minimize exposure. The use of local mechanical
exhaust ventilation is preferred at sources of air contamination such as open process equipment.
Consult National Fire Protection Association (NFPA) Standard 91 for design of exhaust systems.

Storage

Store in a cool, dry place to maintain product performance. Recommended materials of
construction for TKPP solutions include polypropylene and stainless steels. Mild steel is not
satisfactory because the solution dissolves rust (oxides of iron) contaminating the solution.
Aluminum is also not satisfactory because it is subject to corrosion, including severe pitting.

8. EXPOSURE CONTROLS/PERSONAL PROTECTION

Occupational Exposure limit

OSHA and ACGIH have not established specific exposure limits for this material.

Components referred to herein may be regulated by specific Canadian provincial legislation.
Please refer to exposure limits legislated for the province in which the substance will be used.

Respiratory protection

Avoid breathing vapor and/or mist. Use NIOSH/MSHA approved respiratory protection
equipment when airborne exposure is excessive. Consult the respirator manufacturer to
determine appropriate type equipment for a given application. Observe respirator use limitations
specified by NIOSH/MSHA or the manufacturer. Refer to OSHA 29 CFR 1910.133 or European
Standard EN 149.

Hand/Skin protection

Although this product does not present a significant skin concern, minimize skin contamination by
following good industrial practice. Wearing protective gloves is recommended. Wash hands and
contaminated skin thoroughly after handling.

Eye protection

When there is significant potential for eye contact, wear chemical goggles and have eye flushing
