HANDLING PROCEDURES
ACUTE/CHRONIC HAZARDS:
This compound is an irritant to the skin, eyes and mucous membranes.
MINIMUM PROTECTIVE CLOTHING:
When working with this chemical, you should wear
impervious cover-alls, shoe covers and gloves.
RECOMMENDED GLOVE MATERIALS: GLOVE.9
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 material under refrigerated temperatures, and
protect it from moisture and oxidizing agents.
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.
If symptoms such as redness or irritation develop, IMMEDIATELY call a
physician and be prepared to transport the victim 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:
DO NOT INDUCE VOMITING. 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. Be prepared to transport the victim to a
hospital if advised by a physician.
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:
Symptoms of exposure to this compound may include nausea and irritation of
the eyes, nose and mucous membranes.
FIREFIGHTING:
This compound is not very flammable but any fire involving this compound
may produce dangerous vapors. You should evacuate the area. All firefighters
should wear full-body protective clothing and use self-contained breathing
apparatuses.
You should extinguish any fires involving this chemical with a dry
chemical, carbon dioxide, foam, or halon extinguisher.
