SPECIAL FIRE FIGHTING PROCEDURES:
Move container from fire area if possible. Do
not scatter spilled material with high pressure
water streams. Dike fire control water for later
disposal.
UNUSUAL FIRE AND EXPLOSION HAZARDS:
SECTION V:
Use agents suitable for type of
surrounding fire. Avoid breathing
hazardous vapors, keep upwind.
REACTIVITY DATA
STABILITY:
Stable under normal temperatures and pressures.
___________________________________________________________________________
INCOMPATIBILITY (MATERIALS TO AVOID):
Bromine trifluoride (may react violently),
and sulfuric acid and potassium
permanganate (possible explosion).

HAZARDOUS DECOMPOSITION PRODUCTS:
Thermal decomposition may release
corrosive hydrogen chloride.
HAZARDOUS POLYMERIZATION:
SECTION VI:
Has not been reported to occur under
normal temperatures.
HEALTH HAZARD DATA
THRESHOLD LIMIT VALUE:
N/A
EFFECTS OF OVER EXPOSURE:
Inhalation:
No data is available for acute exposure. For chronic exposure,
inhalation of potassium mines and plants has been reported to
result in lesions of the nasal septum due to potassium chloride and
can cause respiratory tract irritation.
Skin:
No data is available for acute and chronic exposure. Causes skin
irritation.
Eye:
Acute exposure may cause irritation. Tested in rabbit eyes,
application of 500 mg for 24 hours resulted in mild irritation.
Concentration solutions may cause a stinging sensation. There is
not data available for chronic exposures.
Ingestion:
Acute exposure may cause gastrointestinal irritation with nausea,
vomiting, epigastric distress, abdominal discomfort, and diarrhea.
High local concentrations in the gastrointestinal tract may cause
esophageal ulceration, if there is dysphagia; gastric ulderation,
especially if perforation of the small bowel. Acute intoxications
orally are uncommon since large doses usually induce vomiting
and normally functioning kidneys excrete potassium rapidly.
However, if an overdose results in hyperkalemia there may be
paretthesias, anesthesias, generalized weakness, mental
confusion, hypotension, and sluggishness.

EMERGENCY AND FIRST AID PROCEDURES:
Inhalation:
Remove from exposure area to fresh air immediately. If breathing
has stopped, perform artificial respiration. Keep person warm and
at rest. Treat symptomatically and supportively. Get medical
attention immediately.
Skin:
Remove contaminated clothing and shoes immediately. Wash
affected area with soap or mild detergent and large amounts of
water until no evidence of chemical remains (approximately 15-20
minutes). Get medical attention immediately.
Eye:
Wash eyes immediately with large amounts of water or normal
saline, occasionally lifting upper and lower lids, until no evidence of
chemical remains (approximately 15-20 minutes). Get medical
attention immediately.
Ingestion:
If victim is conscious, give him large quantities of water, to dilute
the alkali. Do not induce vomiting. Get medical attention
immediately.
SECTION VII:
SPILL OR LEAK PROCEDURES
Highway or railway spills call Chemtrec
(800) 424-9300
STEPS TO BE TAKEN IN CASE MATERIAL IS RELEASED OR SPILLED:
Soak up spill with vermiculite or other absorbent material and place into suitable containers for
later disposal.
WASTE DISPOSAL METHOD: Put in laboratory chemical waste container for removal by
approved chemical waste disposal company.
SECTION VIII:
SPECIAL PROTECTION INFORMATION
VENTILATION:
Provide general dilution ventilation.
OTHER PROTECTIVE EQUIPMENT: Employees must wear appropriate protective
(impervious) clothing and equipment to prevent repeated or prolonged skin contact with
this substance. They must also wear appropriate protective gloves to prevent contact
with this substance along with splash-proof or dust-resistant safety goggles to prevent
eye contact with substance. Emergency eyewash should also be available where there
is any possibility that an employee's eyes may be exposed to this substance. The
employer should provide an eye wash fountain within the immediate work area for
emergency use.
