HANDLING PROCEDURES
ACUTE/CHRONIC HAZARDS:
Irritant
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: P
The following gloves show the best resistance based on permeation
testing. It is recommended that two different glove types be used for
best protection. However, if this chemical makes direct contact with
your glove, or if a tear, puncture or hole develops, remove them at once.
SUGGESTED GLOVES (RAD): Butyl Rubber, Neoprene
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 keep this material in a tightly closed container
under an inert atmosphere, and store it at refrigerated temperatures.
cids and bases.
SPILLS AND LEAKAGE:
If you spill this chemical, use absorbent paper to pick up all liquid
spill 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 alcohol followed by washing 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:
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.
IMMEDIATELY transport the victim after flushing eyes to a hospital even if
no symptoms (such as redness or irritation) develop.
INGESTION:
This compound is a gas, therefore inhalation is the first route of
exposure.
SYMPTOMS:
Symptoms of exposure to this compound include irritation of eyes and throat,
sneezing, coughing, dyspnea, pulmonary edema, conjuctivitis, dermatitis,
burns of skin and mucous membranes.
FIREFIGHTING:
A fire in your laboratory involving this chemical should be
extinguished with a dry chemical, carbon dioxide or halon extinguisher.
