HANDLING PROCEDURES
ACUTE/CHRONIC HAZARDS:
Violent poison! Poisoning may occur by ingestion, absorbtion
through injured skin or inhalation of hydrogen cyanide, liberated
by action of carbon dioxide or other acids. Strong solvents
are corrosive to 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:
Permeation data indicate that butyl rubber gloves may provide pro-
tection to contact with this compound. Butyl rubber over latex gloves
is recommended. However, if this chemical makes direct contact with
your gloves, or if a tear, hole or puncture develops, remove them at once.
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.
OTHER: Not available
STORAGE PRECAUTIONS:
You should store this chemical under refrigerated temperatures
and away from mineral acids 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:
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:
CYANIDES ARE EXTREMELY TOXIC AND FAST-ACTING POISONS. Even though the
induction of vomiting is not usually recommended outside of a physician's care,
if the victim is conscious and not convulsing, it may be worth the risk if a
cyanide has been ingested. Ipecac syrup or salt water may be used to induce
vomiting in such an emergency. IMMEDIATELY call a hospital or poison control
center and transport the victim to a hospital.
If the victim is convulsing or unconscious, do not give anything by mouth,
assure 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: Not available
FIREFIGHTING:
A fire in your laboratory involving this chemical should be
extinguished with a dry chemical, carbon dioxide or halon extinguisher.
