SECTION 7: PRECAUTIONS FOR SAFE HANDLING AND USE/REGULATORY INFORMATION

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

(Minor Spills): Absorb material with ground clay, vermiculite, or similar absorbent material, then place into containers

for removal.

(Major Spills): Dike and contain spill. Eliminate potential sources of ignition, and shut off source of spill if possible.

Remove liquid by chemical vacuum, absorbent, or other safe and approved method and place into containers for legal

disposal. Flush area with water to remove residue, and remove flushed solutions as above.

(Waste Disposal Method): Dispose of all waste in accordance with federal, state and local regulations.

SECTION 8: CONTROL MEASURES

Respiratory Protection: Not normally required; however, if vapor or mist is generated in confined or poorly ventilated

area which causes the TLV's in Section 2 to be exceeded, then use a respirator with appropriate NIOSH approved

cartridges or use supplied air equipment.

Ventilation: Local and mechanical exhaust recommended. Avoid open electrical sources near product vapor areas.

Protective Gloves: Impervious or chemical resistant gloves (consult safety equipment supplier).
