HANDLING PROCEDURES
ACUTE/CHRONIC HAZARDS:
This compound is readily absorbed through the skin.
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: Not available
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: Not available
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 strong 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:
You should dispose of all waste and contaminated materials
associated with this chemical as specified by existing local,
state and federal regulations concerning hazardous waste disposal.
It is suggested that your contaminated materials should be destroyed
by incineration in a special, high temperature ( >2000 degrees F),
chemical incinerator facility.
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:
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.
Generally, the induction of vomiting is NOT recommended outside of a
physician's care due to the risk of aspirating the chemical into the victim's
lungs. However, if the victim is conscious and not convulsing and if medical
help is not readily available, consider the risk of inducing vomiting because
of the high toxicity of the chemical ingested. Ipecac syrup or salt water may
be used in such an emergency. IMMEDIATELY transport the victim to a hospital.
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 the symptoms associated with acute exposure to
this compound is not available.
