Serious Skin ContactWash with a disinfectant soap and cover the contaminated skin with an anti-bacterial cream. Seek immediate medical attention. InhalationIf inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical attention immediately. Serious InhalationEvacuate the victim to a safe area as soon as possible. Loosen tight clothing such as a collar, tie, belt or waistband. If breathing is difficult, administer oxygen. If the victim is not breathing, perform mouth-to-mouth resuscitation.

Chronic Effects on Humans CARCINOGENIC EFFECTS: A4 (Not classifiable for human or animal.) by ACGIH. May cause damage to the following organs: lungs, the nervous system, skin, central nervous system (CNS), eye, lens or cornea, thyroid. Other Toxic Effects onVery hazardous in case of skin contact (permeator), of ingestion, of inhalation. HumansHazardous in case of skin contact (irritant). Not available. Special Remarks on Toxicity to Animals Special Remarks onNot available. Chronic Effects on Humans Acute Potential Health effects: Special Remarks on other Toxic Effects on HumansSkin: Can cause itching and irritation, epecially if skin is wet or moist. It can be absorbed through the skin. May be fatal if absorbed through injured skin with symtpoms similar to those noted for inhalation and ingestion. Eyes: Causes eye irritation and possible eye damage. It can be absorbed through the eyes causing systemic effects. Inhalation: May cause respiratory tract irritation. May be fatal if inhaled. The substance inhibits cellular respiration causing metabolic asphyxiation. May cause headache, weakness, dizziness, labored breathing, nausea, vomiting. May be followed by cardiovascular effects, unconciousness, convulsions, coma, and death Ingestion: May be fatal if swallowed. May cause gastrointestinal tract irritation with abdominal pain, nausea, vomiting, colicky diarrhea, increased salivation, flushing. May affect behavior/nervous system/nervous system(seizures, giddiness, convulsions, change in motor activity, ataxia, headache, dizziness, confusion, muscle weakness possibly progressing to paralysis, tetany, irritability, stupor, vertigo, aniexity, hallucinations, agitation, tremors, feeling of numbness and tingling around the mouth and sometimes the face, neck, and extremities, unconciousness, coma), respiration (hyperventilation, shallow breathing, tachypnea, apnea, breathing difficulty, respiratory failure), cardiovascular system (palpitations, cardiac arrhythmias, slow or rapid heart beat, hypertension, hypotension), and it may cause cyanosis (bluish skin and lips due to deficient oxygenation of the blood). Massive doses by produce sudden loss of conciousness and prompt death from respiratory arrest. Smaller but still lethal doses may prolong the illness for 1 or more hours. A bitter almond odor may be noted on the breath or vomitus. Can also cause hypokalemia, lactic acidosis and dilation of pupils. Chronic Potential Health Effects: Central Nervous system effects (headaches, vertigo, insomnia, memory loss, tremors, fatigue and other symptoms similar to ingestion), metabolic effects (poor appetite, metabolic acidosis, hypokalemia), cardiovascular effects (chest discomfort, palpitations, and other symptoms similar to that of acute ingestion), progressive nerve damage to the eyes resulting in blindness, dermatitis, respiratory tract irritation, eye irritation, thyroid deficiency, goiter, hyperglycemia, anemia, kidney damage, liver damage, or death can occur. Note: The toxicity from Barium Cyanide will be predominantly from cyanide. Barium cyanide Section 12. Ecological Information Not available. Ecotoxicity Not available.
