HANDLING PROCEDURES
ACUTE/CHRONIC HAZARDS:
This compound is a potential eye and skin irritant. When heated to decom-
position it emits very toxic fumes of oxides of carbon, nitrogen and sulfur.
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:
If you spill this chemical, FIRST REMOVE ALL SOURCES OF IGNITION, then
dampen the solid spill material with toluene and transfer the dampened
material to a suitable container. Use absorbent paper dampened with toluene to
pick up any remaining material. Your contaminated clothing and the absorbent
paper should be sealed in a vapor-tight plastic bag for eventual disposal.
Solvent- wash all contaminated surfaces with toluene followed by washing with a
soap and water solution. All exposed surfaces should be analyzed for contami-
nation. 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 compound include skin and eye irritation.
