Hazards and Protection.
Do not store near combustible materials. Store in a cool, dry, well-ventilated area away from incompatible substances.
Wash thoroughly after handling. Wash hands before eating. Use with adequate ventilation. Avoid contact with eyes, skin, and clothing. Keep container tightly closed. Avoid contact with clothing and other combustible materials. Avoid ingestion and inhalation.
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 Standard EN166. Skin: Wear appropriate gloves to prevent skin exposure. Clothing: Wear appropriate protective clothing to minimize contact with skin.
Follow the OSHA respirator regulations found in 29CFR 1910.134 or European Standard EN 149. Always use a NIOSH or European Standard EN 149 approved respirator when necessary.
Vacuum or sweep up material and place into a suitable disposal container. Avoid runoff into storm sewers and ditches which lead to waterways. Clean up spills immediately, using the appropriate protective equipment. Avoid generating dusty conditions. Remove all sources of ignition.
Corrodes metal. Explodes on contact with acetic anhydride producing acetyl peroxide, reacts violently with propane when heated, ignites when mixed with calcium-silicone alloys, powdered aluminum, powdered magnesium, and water + organic compounds, and ignites wood with the friction it creates. Incompatible with hydrogen sulfide, water, peroxyformic acid, hydroxylamine solution, organic matter and a mixture of manganese, zinc, and barium nitrate.
Barium oxide, oxygen.
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Strong oxidizer. Contact with combustible materials may cause a fire. Extinguishing media: Use water spray to cool fire-exposed containers. Use water only!
This material itself is non-combustible.
Can increase intensity of fire.
Fire may produce irritating, corrosive and/or toxic gases.
TLV (Barium and soluble compounds, as Ba): 0.5 mg/m3 A4 (TWA) (ACGIH 1996).
Abnormally low blood pressure and apnea have been reported with severe poisonings. Cerebral edema, cerebral gas embolism, cerebral infarction, and seizures have been reported following ingestion of concentrated (35%) solutions. Death has been reported as a result of embolic cerebrovascular injury.
Causes gastrointestinal irritation with nausea, vomiting and diarrhea. May cause respiratory failure. May cause circulatory system failure. May cause hemorrhaging of the digestive tract. Causes potassium deficiency and may affect the function of the heart and central nervous system. Symptoms may include salivation, vomiting, severe abdominal pain, violent purging, cardiac rhythm changes, dilated pupils, confusion, dizziness, muscle tremors, convulsions, paralysis, and death.
Benign pneumonconsis from chronic inhalation. Irritation of the nose and throat. Excessive salivation, vomiting, violent diarrhea, tremors, muscular paralysis and CNS paralysis.
Causes eye irritation.
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.
Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid.
Get medical aid. Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes.
Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid.
