MINIMUM PROTECTIVE CLOTHING: Not available

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

Butyl rubber          North B-161        0.40 mm            480 min

Neoprene              Pioneer N-44       0.56 mm            480 min

Viton/Neoprene        MSA Valutex        0.58 mm            480 min

PVA                   Edmont 25-950      0.33 mm            480 min


RECOMMENDED RESPIRATOR:
Where the neat test chemical is weighed and diluted, wear a NIOSH-
approved half face respirator equipped with an organic vapor/acid gas
cartridge (specific for organic vapors, HCl, acid gas and SO2) with a
dust/mist filter.

OTHER: Not available

STORAGE PRECAUTIONS:
You should protect this chemical from exposure to light. Keep
the container tightly closed under an inert atmosphere, and store
under refrigerated temperatures.

SPILLS AND LEAKAGE:
Should a spill occur while you are handling this chemical, FIRST REMOVE
ALL SOURCES OF IGNITION, then you should dampen the solid spill material with
60-70% ethanol and transfer the dampened material to a suitable container. Use
absorbent paper dampened with 60-70% ethanol to pick up any remaining material.
Seal the absorbent paper, and any of your clothes, which may be contaminated,
in a vapor-tight plastic bag for eventual disposal. Solvent wash all contamin-
ated surfaces with 60-70% ethanol followed by washing 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.
If symptoms such as redness or irritation develop, IMMEDIATELY call a
physician and be prepared to transport the victim to a hospital for treatment.

INHALATION:
IMMEDIATELY leave the contaminated area; take deep breaths of fresh air.
If symptoms (such as wheezing, coughing, shortness of breath, or burning in
the mouth, throat, or chest) develop, call a physician and be prepared to
transport the victim to a hospital.
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 chemical may include skin sensitization
reactions, eye irritation and injury, skin irritation, dermatitis, blackened
skin and bronchial asthma [036]. Other symptoms may include allergic skin
reactions, irritation of the mucous membranes, nose, throat and lungs, cough-
ing, burning sensation, runny nose, sore throat, methemoglobinemia, cyanosis,
headache, dizziness, drowsiness, mental confusion, pulmonary edema, kidney and
liver damage, central nervous system effects and conjunctivitis. Eye contact
may cause discomfort, tearing, blurring of vision, reddening, partial clouding
of the cornea and swelling of the eye and surrounding tissue [058]. Dysuria
and eosinophiluria may also occur [395]. Exposure may also result in
respiratory tract irritation [269].
