Section 5 Effects of Overexposure
Acute Effects
Eye: Direct eye contact may cause temporary discomfort with mild redness and dryness
similar to windburn.
Skin: a single prolonged exposure (24 to 48 hours) causes no known adverse effect.
Inhalation: No irritation to eyes and respiratory passages. No injury is likely from
relatively short exposures of less than 8 hours.
Oral: Small amounts transferred to the mouth by fingers during use, etc., should not
injure. Swallowing large amounts may cause digestive discomfort.
Repeated Exposures
Skin: None known
Inhalation: None known
Oral: None known
Special Hazards
Carcinogens, teratogens, mutagens, reproductive toxins,
sensitizers: None known
Comments: The above listed potential effects of over exposure are based on actual data,
results of studies performed upon similar compositions component data and/or expert
review of the product.
Section 6 Emergency First Aid Procedures:
Skin: No first aid should be needed
Inhalation: No first aid should be needed
Oral: No first aid should be needed
Eye: Immediately flush with water

Incompatibilities (materials to avoid): Oxidizing materials can cause a reaction.
Conditions to Avoid: None
Hazardous Polymerization: Will not occur.
Hazardous Decomposition Products: Carbon oxides and traces of incompletely burned
carbon compounds. Silicon dioxide. Formaldehyde.
Section 8 Protective Equipment for Routine Handling and Spill Cleanup:
Ventilation: General ventilation is recommended. Should not need local exhaust.
Respiratory: No respiratory protection should be needed
Eyes: Use proper protection - safety glasses as a minimum.
Skin: Washing at mealtime and end of shift is adequate. No gloves needed.
Precautionary Measures: Avoid eye contact. Use reasonable care.
NOTE: these precautions are for room temperature handling. Use at elevated
temperatures, or aerosol/spray applications, may require added precautions.
Section 9 Accidental Release Measures:
Disposal of collected product, residues, and cleanup materials may be governmentally
regulated, Observe all applicable local, state, and federal waste management regulations.
Mop up or wipe up, or soak up with absorbent and contain for salvage or disposal. For
large spills, provide diking or other appropriate containment to keep material from
spreading. Clean any remaining slippery surfaces by appropriate techniques, such as:
several moppings or swabbings with appropriate solvents; washing with mild, caustic
detergents or solutions; or high pressure steam for large areas. For nonsilicones, use
typical industrial cleaning materials. Observe any safety precautions applicable to the
cleaning material being used. Observe all personal protection equipment
recommendations described in Sections 5 and 8. Local, state, and federal reporting
requirements may apply to spills or releases of this material into the environment. See
applicable regulatory compliance information in Section 15.
NOTE: See section 8 for personal protective equipment for spills.
