HANDLING PROCEDURES





ACUTE/CHRONIC HAZARDS:
When heated to decomposition this compound emits toxic fumes of carbon
monoxide, carbon dioxide and oxides of nitrogen [043,058,269]. It is poison by
intraperitoneal and moderately toxic by ingestion [043]. It is harmful by skin
absorption and may be harmful by inhalation [269].

MINIMUM PROTECTIVE CLOTHING:
If Tyvek-type disposable protective clothing is not worn during
handling of this chemical, wear disposable Tyvek-type sleeves taped to
your gloves.

RECOMMENDED GLOVE MATERIALS:
GlovES+ Expert System Glove Types For The Neat (Undiluted) Chemical:
This chemical has not been tested for permeation by Radian Corporation;
however, the GlovES+ expert system was used to extrapolate permeation test
information from compounds in the same chemical class. The GlovES+ system uses
permeation data from literature sources; therefore, extra safety margins should
be used with the estimated protection time(s). If this chemical makes direct
contact with your glove, or if a tear, puncture or hole develops, replace them
at once.
The GlovES+ expert system is a tool that can help people better manage
protection from chemicals, however this tool cannot replace sound judgment nor
make technical decisions. Our GlovES+ expert system is designed to offer
initial advice and assistance in glove selection while the final glove
selection should be made by knowledgeable individuals based on the specific
circumstances involved.

Glove Type            Model Number      Thickness   Estimated Protection Time

PE/EVAL/PE            Safety 4 4H        0.07 mm            240 min

Butyl rubber          North B-174        0.63 mm            240 min


RECOMMENDED RESPIRATOR:
Where the neat test chemical is weighed and diluted, wear a NIOSH-
approved half face respirator equipped with a combination filter cartridge,
i.e. organic vapor/acid gas/HEPA (specific for organic vapors, HCl, acid
gas, SO2 and a high efficiency particulate filter).

OTHER:
Since this chemical is a known or suspected carcinogen you should contact
a physician for advice regarding the possible long term health effects and
potential recommendation for medical monitoring. Recommendations from the
physician will depend upon the specific compound, its chemical, physical and
toxicity properties, the exposure level, length of exposure, and the route
of exposure.

STORAGE PRECAUTIONS:
You should keep this material in a tightly closed container
under an inert atmosphere, and store it at refrigerated temperatures.

SPILLS AND LEAKAGE:
If you spill this chemical, you should dampen the solid spill material
with water,then transfer the dampened material to a suitable container. Use
absorbent paper dampened with water to pick up any remaining material. Seal
your contaminated clothing and the absorbent paper in a vapor-tight plastic
bag for eventual disposal. Wash all contaminated surfaces with a soap
and water solution. Do not reenter the contaminated area until the Safety
Officer (or other responsible person) has verified that the area has been
properly cleaned.

DISPOSAL AND WASTE TREATMENT: Not available





EMERGENCY PROCEDURES





SKIN CONTACT:
IMMEDIATELY flood affected skin with water while removing and isolating
all contaminated clothing. Gently wash all affected skin areas thoroughly
with soap and water.
IMMEDIATELY call a hospital or poison control center even if no symptoms
(such as redness or irritation) develop.
IMMEDIATELY transport the victim to a hospital for treatment after
washing the affected areas.

INHALATION:
IMMEDIATELY leave the contaminated area; take deep breaths of fresh air.
IMMEDIATELY call a physician and be prepared to transport the victim to a
hospital even if no symptoms (such as wheezing, coughing, shortness of breath,
or burning in the mouth, throat, or chest) develop.
Provide proper respiratory protection to rescuers entering an unknown
atmosphere. Whenever possible, Self-Contained Breathing Apparatus (SCBA)
should be used; if not available, use a level of protection greater than or
equal to that advised under Respirator Recommendation.

EYE CONTACT:
First check the victim for contact lenses and remove if present. Flush
victim's eyes with water or normal saline solution for 20 to 30 minutes while
simultaneously calling a hospital or poison control center.
Do not put any ointments, oils, or medication in the victim's eyes without
specific instructions from a physician.
IMMEDIATELY transport the victim after flushing eyes to a hospital even if
no symptoms (such as redness or irritation) develop.

INGESTION:
DO NOT INDUCE VOMITING. If the victim is conscious and not convulsing,
give 1 or 2 glasses of water to dilute the chemical and IMMEDIATELY call a
hospital or poison control center. Be prepared to transport the victim to a
hospital if advised by a physician.
If the victim is convulsing or unconscious, do not give anything by mouth,
ensure that the victim's airway is open and lay the victim on his/her side with
the head lower than the body. DO NOT INDUCE VOMITING. IMMEDIATELY transport
the victim to a hospital.

SYMPTOMS:
Symptoms of exposure to this compound may include irritation of the eyes,
skin and upper respiratory tract, depression, dyspnea, labored respiration,
diarrhea, ataxia, vomiting, convulsions, coma, lung injury and, possibly,
thyroid effects [058]. It may also enhance yellowing or browning of lenses
with ultraviolet exposure [099].
