  1. Interesting that the MSDS for methyl iodide states the following:
    "DANGER! MAY BE FATAL IF SWALLOWED, INHALED OR ABSORBED THROUGH SKIN. AFFECTS CENTRAL NERVOUS SYSTEM. CAUSES IRRITATION TO SKIN, EYES AND RESPIRATORY TRACT.
    Potential Health Effects
    Inhalation: Inhalation of vapors can irritate the respiratory tract. Overexposure may produce symptoms of vertigo, delirium and mental disturbances. Other symptoms may include slurred speech, drowsiness, coughing, nausea and vomiting. Higher exposures can cause a build up of fluid in the lungs which can cause death.
    Ingestion may damage the gastro-intestinal tract. Severe intoxication can occur with symptoms of central nervous system depression. Coma, convulsions, and death may follow.
    Skin contact: Causes irritation, rash and blister formation. Prolonged contact can cause skin burns. Can be absorbed through skin with toxic effects.
    Vapors can cause irritation. Splashes may cause severe irritation with eye damage.
    Chronic exposure: Prolonged or repeated exposure to smaller doses cause primarily central nervous system effects. Symptoms may include slurred speech, blurred vision, Parkinsonian rigidity and memory defects. Has been shown to cause cancer in animals and may be linked to cancer in humans.
    Aggravation of Pre-existing Conditions:
     

    Persons with pre-existing skin disorders or eye problems, or impaired respiratory function may be more susceptible to the effects of the substance."

     

    Oh, but it is safe, right? 

  2. Thanks for posting.

    You will notice that many , MSDS and Label Information is SCARY to read.  Look at Aspirin or Coffee or Pepsi Cola Concentrate.  You might be surprised.

    Your child will be fine.

    ASPIRIN:
    WARNING! HARMFUL IF SWALLOWED OR INHALED. CAUSES IRRITATION TO SKIN, EYESAND RESPIRATORY TRACT. MAY CAUSE ALLERGIC RESPIRATORY REACTION. POSSIBLEBIRTH DEFECT HAZARD. MAY CAUSE BIRTH DEFECTS BASED ON ANIMAL DATA.AFFECTS THE RESPIRATORY SYSTEM, LIVER, KIDNEYS, EYES, SKIN AND BLOOD.

    Sodium fluoride:

    A preservative, oral care in cosmetics, toothpastes, dentifrices, cigarettes. See Fluoride. 

    MSDS: DANGER! MAY BE FATAL IF SWALLOWED OR INHALED. AFFECTS RESPIRATORY SYSTEM, HEART, SKELETON, CIRCULATORY SYSTEM, CENTRAL NERVOUS SYSTEM AND KIDNEYS. CAUSES IRRITATION TO SKIN, EYES AND RESPIRATORY TRACT. IRRITATION EFFECTS MAY BE DELAYED. 

    Potential Health Effects 
    If inhaled or swallowed, this compound can cause fluoride poisoning. Early symptoms include nausea, vomiting, diarrhoea, and weakness. Later effects include central nervous system effects, cardiovascular effects and death. 

    Inhalation: Causes severe irritation to the respiratory tract, symptoms may include coughing, sore throat, and laboured breathing. May be absorbed through inhalation of dust; symptoms may parallel those from ingestion exposure. Irritation effects may not appear immediately. 
    Ingestion: Toxic! May cause salivation, nausea, vomiting, diarrhoea, and abdominal pain. Symptoms of weakness, tremors, shallow respiration, carpopedal spasm, convulsions, and coma may follow. May cause brain and kidney damage. Affects heart and circulatory system. Death may occur from respiratory paralysis. Estimated lethal dose = 5-l0 grams. 
    Skin Contact: Causes irritation, with redness and pain. Solutions are corrosive. Effects may not appear immediately. 
    Eye Contact: Eye irritant! May cause irritation and serious eye damage. Effects may not immediately appear. 
    Chronic Exposure: Chronic exposure may cause mottling of teeth and bone damage (osteosclerosis) and fluorosis. Symptoms of fluorosis include brittle bones, weight loss, anaemia, calcified ligaments, general ill health and joint stiffness. 
    Aggravation of Pre-existing Conditions: Populations that appear to be at increased risk from the effects of fluoride are individuals that suffer from diabetes insipidus or some forms of renal impairment.
