HANDLING PROCEDURES





ACUTE/CHRONIC HAZARDS:
When heated to decomposition this compound emits toxic fumes.

MINIMUM PROTECTIVE CLOTHING: Not available

RECOMMENDED GLOVE MATERIALS:
Recommended Glove Type For Use With Neat (Undiluted) Chemical:
Recommendations based on permeation test results are made for handling
the neat (undiluted) chemical. If this chemical makes direct contact with
your glove, or if a tear, puncture or hole develops, replace them at once.

Suggested Glove Type(s) (RAD): No information available

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 store this chemical under refrigerated temperatures,
and keep it away from oxidizing materials. STORE AWAY FROM SOURCES
OF IGNITION.

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

OTHER: 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:
Information concerning symptoms of exposure to this chemical is not available.
