EMERGENCY OVERVIEW
Harmful by inhalation and if swallowed.Moisture sensitive.
Potential Health Effects
Eye:
Causes severe eye irritation and possible injury.
Skin:
Causes skin irritation.
Ingestion:
May cause irritation of the digestive tract and possible burns. The
barium ion is a muscle poison causing stimulation and then
paralysis. Initial symptoms are gastrointestinal, including nausea,
vomiting, colic, and diarrhea, followed by myocardial and general
muscular stimulation with tingling in the extremities. The barium ion
is a chemical antagonist of potassium, and it appears that the
symptoms of barium poisoning are attributable to Ba2+-induced
hypokalemia. The effect is probably due to a transfer of K+ from
extracellular to intracellular compartments.
Inhalation:
May cause respiratory tract irritation.
Chronic:
No information found.
**** SECTION 4 - FIRST AID MEASURES ****
Eyes:
Get medical aid immediately. Do NOT allow victim to rub eyes or keep
eyes closed. Extensive irrigation with water is required (at least 30
minutes).
Skin:
Get medical aid. Flush skin with plenty of water for at least 15
minutes while removing contaminated clothing and shoes.
Ingestion:
Do not induce vomiting. If victim is conscious and alert, give 2-4
cupfuls of milk or water. Never give anything by mouth to an
unconscious person. Get medical aid immediately.
Inhalation:
Get medical aid immediately. Remove from exposure and move to fresh
air immediately. If breathing is difficult, give oxygen.
Notes to Physician:
Signs and symptoms of hypokalemia are relieved by intravenous
infusion of K+. Institute cardiac monitoring for all significant
ingestions of soluble barium salts. Consider the use of calcium
gluconate for muscle spasms and gastric lavage followed by saline
catharsis if soluble barium salts are ingested.
**** SECTION 5 - FIRE FIGHTING MEASURES ****
General Information:
As in any fire, wear a self-contained breathing apparatus in
pressure-demand, MSHA/NIOSH (approved or equivalent), and full
protective gear. Material will not burn.
Extinguishing Media:
Substance is noncombustible; use agent most appropriate to
extinguish surrounding fire.
**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Vacuum or sweep up material and place into a suitable disposal
container. Avoid generating dusty conditions. Provide ventilation.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Use with adequate ventilation. Minimize dust
generation and accumulation. Avoid breathing dust. Do not get in
eyes. Avoid contact with skin and clothing.
Storage:
Store in a cool, dry place. Store in a tightly closed container.
Store under an inert atmosphere.
**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****
Engineering Controls:
Facilities storing or utilizing this material should be equipped
with an eyewash facility and a safety shower. Use adequate general or
local exhaust ventilation to keep airborne concentrations below the
permissible exposure limits.

Personal Protective Equipment
Eyes:
Wear appropriate protective eyeglasses or chemical
safety goggles as described by OSHA's eye and face
protection regulations in 29 CFR 1910.133 or European

exposure.
Clothing:
Wear appropriate protective clothing to prevent skin
exposure.
Respirators:
Follow the OSHA respirator regulations found in 29
CFR 1910.134 or European Standard EN 149. Use a
NIOSH/MSHA or European Standard EN 149 approved
respirator if exposure limits are exceeded or if
irritation or other symptoms are experienced.
