ACCIDENTAL RELEASE MEASURES
__________________________________________________________________
GENERAL:
This material should be prevented from contaminating soil or from
entering sewerage and drainage systems and bodies of water.
Isolate hazard area. Keep unnecessary and unprotected personnel
from entering. Prevent skin and eye contact. See Exposure
Controls/Personal Protection.
SMALL SPILL:
Absorb spill with inert material (e.g., dry sand or earth), then
place in a chemical waste container.
LARGE SPILL:
Shut off leak, if safe to do so. Clean up spills immediately,
observing precautions in Protective Equipment section. Contain
spilled liquid with sand or earth. Retain all contaminated water
for removal and treatment.

HANDLING & STORAGE
_________________________________________________________________________
HANDLING:
Use with adequate ventilation. Avoid contact with skin and
eyes. Wash thoroughly after handling. Follow all MSDS/label
precautions even after container is emptied because it may retain
product residues.
STORAGE: Keep container closed when not in use.
________________________________________________________________________
EXPOSURE CONTROLS/PERSONAL PROTECTION
________________________________________________________________________
EXPOSURE LEVELS: None established.
ENGINEERING CONTROLS:
Use process enclosures, local exhaust ventilation, or other
engineering controls to control sources of dust, mist or vapor.
RESPIRATORY PROTECTIONS:
Use a NIOSH/MSHA approved air purifying respirator as needed to
control exposure. Consult with respirator manufacturer to
determine respirator selection, use, and limitations. Use a
positive pressure air supplied respirator for uncontrolled
releases or when air purifying respirator limitations may be
exceeded. Follow respiratory protection program requirements
(OSHA 1910.134 and ANSI Z88.2) for all respirator use.
EYE/FACE PROTECTION:
Use safety glasses. Where contact with the eyes is likely, use
chemical goggles. Use a face shield as needed.
SKIN PROTECTION:
Use impervious gloves. Use clean protective body-covering
clothing as needed to minimize contact with clothing and skin.
