BARIUM
IMPORTANT DATA
Physical State; Appearance
YELLOWISH TO WHITE LUSTROUS SOLID IN VARIOUS
FORMS.
Physical dangers
Dust explosion possible if in powder or granular form, mixed
with air.
Chemical dangers
The substance may spontaneously ignite on contact with air (if
in powder form). The substance is a strong reducing agent and
reacts violently with oxidants and acids. Reacts violently with
halogenated solvents. Reacts with water, forming
flammable/explosive gas (hydrogen - see ICSC 0001), causing
fire and explosion hazard.
Occupational exposure limits
TLV: 0.5 mg/m
3
(as TWA) (ACGIH 1999).
Routes of exposure
The substance can be absorbed into the body by ingestion.
Effects of short-term exposure
The substance irritates the eyes, the skin and the respiratory
tract.
PHYSICAL PROPERTIES
ENVIRONMENTAL DATA
NOTES
Reacts violently with fire extinguishing agents such as water, bicarbonate, powder, foam, and carbon dioxide.
Rinse contaminated clothes (fire hazard) with plenty of water.

FIRE
Not combustible but enhances
combustion of other substances.
Many reactions may cause fire or
explosion.
NO contact with flammable
substances. NO contact with
organic substances, metal powders,
ammonium salts, and reducing
agents.
In case of fire in the surroundings:
all extinguishing agents allowed.
EXPLOSION
Risk of fire and explosion on
contact with : see Chemical
Dangers.
Do NOT expose to friction or shock.
Prevent deposition of dust; closed
system, dust explosion-proof
electrical equipment and lighting.
In case of fire: keep drums, etc.,
cool by spraying with water. Combat
fire from a sheltered position.
EXPOSURE
PREVENT DISPERSION OF DUST!
STRICT HYGIENE!
Inhalation
Cough. Sore throat. (See
Ingestion).
Ventilation (not if powder), local
exhaust, or breathing protection.
Fresh air, rest. Artificial respiration if
indicated. Refer for medical
attention.
Skin
Redness.
Protective gloves.
First rinse with plenty of water, then
remove contaminated clothes and
rinse again. Refer for medical
attention.
Eyes
Redness. Pain.
Safety goggles, or eye protection in
combination with breathing
protection.
First rinse with plenty of water for
several minutes (remove contact
lenses if easily possible), then take
to a doctor.
Ingestion
Abdominal pain. Blue lips or
fingernails. Blue skin. Confusion.
Convulsions. Diarrhoea. Dizziness.
Headache. Nausea.
Unconsciousness. Vomiting.
Weakness.
Do not eat, drink, or smoke during
work.
Rinse mouth. Induce vomiting
(ONLY IN
CONSCIOUS
PERSONS!). Rest. Refer for
medical attention.
SPILLAGE DISPOSAL
PACKAGING & LABELLING
Consult an expert if large spill! Sweep spilled
substance into containers; if appropriate, moisten
first to prevent dusting. Wash away remainder with
plenty of water. Do NOT absorb in saw-dust or other
combustible absorbents. Do NOT let this chemical
enter the environment. (Extra personal protection:
P2 filter respirator for harmful particles).

BARIUM CHLORATE
IMPORTANT DATA
Physical State; Appearance
COLOURLESS CRYSTALLINE POWDER
Chemical dangers
Shock-sensitive compounds are formed with organic
compounds, reducing agents, ammonia-containing agents, and
metal powders. The substance decomposes violently on heating
producing oxygen and toxic fumes, causing fire and explosion
hazard. The substance is a strong oxidant and reacts with
combustible and reducing materials.
Occupational exposure limits
TLV (as Ba): 0.5 mg/m
3
(as TWA) A4 (ACGIH 1999). 0.5 mg/m

EC OELs
Routes of exposure
The substance can be absorbed into the body by inhalation and
by ingestion.
Inhalation risk
Evaporation at 20°C is negligible; a harmful concentration of
airborne particles can, however, be reached quickly when
dispersed, especially if powdered.
Effects of short-term exposure
The substance irritates the eyes, the skin and the respiratory
tract. The substance may cause effects on the blood and
nervous system, resulting in formation of methaemoglobin.
Exposure could cause hypokalemia, resulting in cardiac
disorders and muscular disorders. The effects may be delayed.
Medical observation is indicated. Exposure may result in death.
PHYSICAL PROPERTIES
ENVIRONMENTAL DATA
The substance is harmful to aquatic organisms.
NOTES
Depending on the degree of exposure, periodic medical examination is indicated. The symptoms of paralysis do not become
manifest until some hours have passed. Specific treatment is necessary in case of poisoning with this substance; the appropriate
means with instructions must be available. Rinse contaminated clothes (fire hazard) with plenty of water. 10294-38-9 is a CAS
registry number for Barium chlorate, monohydrate. Will turn shock-sensitive if contaminated with: see Chemical Dangers.
