HANDLING PROCEDURES






ACUTE/CHRONIC HAZARDS:
This chemical is highly toxic, a powerful irritant, and causes blistering.
It caused allergic reactions and dermatitis by skin contact or inhalation.
It can be 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 an organic vapor/acid gas
cartridge (specific for organic vapors, HCl, acid gas and SO2) with a
dust/mist filter.
Splash proof safety goggles should be worn while handling this
chemical. Alternatively, a full face respirator, equipped as above,
may be used to provide simultaneous eye and respiratory protection.

OTHER: Not available

STORAGE PRECAUTIONS:
You should store this material in a refrigerator away from oxidizing
materials.

SPILLS AND LEAKAGE:
Should a spill occur while you are handling this chemical, you should
dampen the solid spill material with alcohol, then transfer the dampened
material to a suitable container. Use absorbent paper dampened with alcohol
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 contaminated surfaces with alcohol followed by
washing with a strong soap and water solution. Do not reenter the contaminate
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.
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. Corrosive chemicals will destroy the membranes
of the mouth, throat, and esophagus and, in addition, have a high risk of
being aspirated into the victim's lungs during vomiting which increases the
medical problems.
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. 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. Transport the victim
IMMEDIATELY to a hospital.

SYMPTOMS:
Symptoms of exposure to this compound may include irritation to the eyes,
skin and mucous membranes.
