Additional info: Observe for any symptoms for several hours after exposure. Follow up with medical attention if symptoms develop.

SECTION 5. FIREFIGHTING MEASURES

General info: Use proper safety equipment. If this product is involved in a fire Sodium sulfite and metal oxide fume can be released.
Extinguishing Method / Equipment: Use water spray or dry chemical, carbon dioxide. DO NOT use organics
Hazardous Decomposition Info: Constituents associated with burning / combustion are to be considered toxic. Firefighters should
wear self-contained breathing apparatus and full protective gear.
Use NIOSH/MSHA approved self-contained breathing apparatus and full protective clothing.
EMITS TOXIC FUMES UNDER FIRE CONDITIONS.

SECTION 6. ACCIDENTAL RELEASE MEASURES

Personal precautions, protective equipment and procedures: Keep unnecessary personnel away. Keep people away from and upwind of spill/leak. Eliminate all
ignition sources (no smoking, flares, sparks, or flames in immediate area). Wear appropriate
protective equipment (SCBA) and clothing during clean-up. Avoid breathing vapor. Ventilate
area if easy to do so and wash spill site after clean up is complete. Contact local authorities if
significant spillages cannot be contained. For personal protection, see section 8 of the SDS.
Containment Equipment and Procedures: Large Spills: Dike major spills. Absorb with liquid-binding material (sand, diatomite, acid binders,
universal binders, sawdust). Use neutralizing agent. Dispose contaminated material as waste. Ensure adequate ventilation
Cleanup procedures: Collect all contaminated media, or other cleanup materials into a waste receptacle. If cleaning surface is necessary, utilize vacuum cleaner, provided adequate ventilation is available.

SECTION 7. HANDLING AND STORAGE

Safe Handling Precautions: Do not handle until all safety precautions have been read and understood. Keep containers tightly closed Ensure adequate ventilation. Avoid breathing vapor. Avoid contact with eyes, skin, and clothing. Avoid prolonged exposure. Wear appropriate personal protective equipment and wash thoroughly after handling.
Work/Hygienic Practices: Always use good personal hygiene after handling
Recommendations for Storage: Store in the dark. Store away from strong bases. Keep from freezing. Keep container upright
Other precautions: 0.01 ppm high efficiency particular respirator/supplied air respirator/self-contained breathing apparatus; 0.2 ppm same as above with full face piece; 1 ppm powdered air purifying respirator with high efficiency filter/type C supplied air respirator operated in pressure demand mode. Store in a sealed container, plastic or plastic liner, in a cool, well ventilated, dry area away from volatile acids.

SECTION 8. EXPOSURE CONTROLS/PERSONAL PROTECTION

General / Engineering Controls: Ventilation: Local Exhaust: Required in handling area
Mechanical: Desirable to insure concentration of material below TLV/TWA levels
Other: Closed ventilation system (Laboratory Fume Hood)
Work Clothing: Protective work clothing which covers skin and prevents exposures. Lab coat/apron, flame and chemical resistant protective clothing, eye wash, safety shower, and hygiene facilities for washing.
