MINIMUM PROTECTIVE CLOTHING: Not available
RECOMMENDED GLOVE MATERIALS: Not available
RECOMMENDED RESPIRATOR:
When working with this chemical, wear a NIOSH-approved full face
positive pressure supplied-air respirator or a self-contained breathing
apparatus (SCBA).
OTHER: Not available
STORAGE PRECAUTIONS:
You should store this material in a refrigerator.
SPILLS AND LEAKAGE: Not available
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:
CAUTION: Exposure of skin to compressed gases may result in freezing
of the skin. Treatment for frostbite may be necessary.
Remove the victim from the source of contamination. IMMEDIATELY wash
affected areas gently with COLD water (and soap, if necessary) while
removing and isolating all contaminated clothing. Dry carefully with clean,
soft towels.
If symptoms such as inflammation or irritation develop, IMMEDIATELY call
a physician or go 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.
If symptoms (such as redness or irritation) develop, immediately transport
the victim to a hospital.
INGESTION:
This compound is a gas, therefore inhalation is the first route of
exposure.
SYMPTOMS:
Central Nervous depression, paresthesias, tinnitus, slurred speech,
apprehension, cardiac arrhythmias.
FIREFIGHTING: Not available
