-HANDLING PROCEDURES
===================
*ACUTE/CHRONIC HAZARDS:
This material may be irritating to eyes and mucous membranes. In high
concentrations it may be narcotic. When heated to decomposition it emits
acrid smoke and 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.
*STORAGE PRECAUTIONS:
You should store this chemical under refrigerated conditions
and away from all organic compounds.
*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, the exposure level and the
route of exposure.
*SPILLS AND LEAKAGE:
If you spill this chemical, FIRST REMOVE ALL SOURCES OF IGNITION, then
dampen the solid spill material with toluene, then transfer the dampened
material to a suitable container. Use absorbent paper dampened with toluene
to pick up any remaining material. Your contaminated clothing and 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. 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 WASTES 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 may include skin, eyes and mucous
membranes.
