FIRST AID MEASURES
________________________________________________________________
BREATHING: Remove to fresh air. If not breathing, give artificial
respiration or give oxygen by trained personnel. Seek
immediate medical attention.
SKIN:
Immediately flush with large amounts of water for at least 15
minutes. Use soap if available. Remove contaminated clothing,
including shoes, after flushing has begun. Get prompt medical
2
attention if symptoms occur. Thoroughly wash or discard clothes
and shoes before reuse.

FIRE FIGHTING PROCEDURES:
Evacuate area and fight fire from safe distance. Wear self
contained breathing apparatus pressure demand (MSHA/NIOSH
approved or equivalent) and full protective gear.
SPECIAL FIRE FIGHTING PROCEDURES:
Can burn in fire releasing toxic vapors. As in any fire wear
self contained breathing apparatus pressure demand and full
protective gear.

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:
Sweep or scoop material into a chemical waste container. Avoid
raising dust. Scrub area with detergent and water.
LARGE SPILL:
Shut off spill if safe to do so. Clean up spills immediately,
observing precautions in PROTECTIVE EQUIPMENT SECTION. Vacuum or
sweep up material and place in a disposal container.

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 they may
retain produce residues.
STORAGE: Keep container closed when not is use.
________________________________________________________________
EXPOSURE CONTROLS/PERSONAL PROTECTION
________________________________________________________________
EXPOSURE LIMITS: Not available.
ENGINEERING CONTROLS:
Use process enclosures, local exhaust ventilation, or other
engineering controls to control sources of dust, mist or vapor.

RESPIRATORY PROTECTION:
A NIOSH/MSHA approved air purifying respirator may be permissible
under certain circumstances where airborne concentrations are
expected to exceed exposure limits if established. Consult with
respirator's manufacturer to determine the appropriate type of
equipment for a given application. Protection provided by air
purifying respirators is limited. Use a positive pressure air
supplied respirator if there is any potential for an uncontrolled
release, exposure levels are not known, or any other
circumstances where air purifying respirators may not provide
adequate protection. A respiratory protection program that meets
OSHA 1910.134 and ANSI Z88.2 requirements must be followed
whenever workplace conditions warrant respirator's use.
EYE/FACE PROTECTION:
Wear safety glasses with side shields (or goggles) and a face
shield.
SKIN PROTECTION:
Wear impervious gloves and chemical protective clothing,
including impervious sleevelets, overalls, aprons or boots as
needed to prevent contact with skin.
