Check for and remove any contact lenses. In case of contact, immediately flush eyes with plenty of water for at least
Eye Contact
15 minutes. Cold water may be used. Get medical attention.

If breathing is difficult, administer oxygen. If the victim is not breathing, perform mouth-to-mouth resuscitation.
WARNING: It may be hazardous to the person providing aid to give mouth-to-mouth resuscitation when the inhaled
material is toxic, infectious or corrosive. Seek immediate medical attention.
If swallowed, do not induce vomiting unless directed to do so by medical personnel. Never give anything by mouth to
Ingestion
an unconscious person. Loosen tight clothing such as a collar, tie, belt or waistband. Get medical attention
immediately.
Serious IngestionNotes to Physcian:
Exposure should be treated as cyanide posioning.
Antidote: Always have a cyanide antidote kit on hand when working with cyanide compounds. Get medical advice to
use.

May cause damage to the following organs: lungs, the nervous system, skin, central nervous system (CNS), eye, lens or
cornea, thyroid.

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.
