lorsban health issues

[TOM4CWB]

Groundspeed,

I agree. A good test could be done to show the direct exposure and density with dyed water. If any height at all... the distribution would have been wide... a forest fire water bomber drop being a good example.

Coming out of a hose leak would have been on a magnitude many times less... but it could be simulated and measured.

If people were under this plane... I bet they would see it falling after the plane went over and in a yard any shelter would have stopped direct exposure of any significance.

This isn't radioactive fallout.

RD,

Losban has been around since 1965. Long term exposure will do the most harm.

"TOXICOLOGICAL INFORMATION
Chlorpyrifos is an organophosphate that is a cholinesterase inhibitor. Typical symptoms of overexposure to cholinesterase inhibitors include headache, nausea, dizziness, sweating, salivation, runny nose and eyes. This may progress to muscle twitching, weakness, tremors, incoordination, vomiting, abdominal cramps and diarrhea in more serious poisonings. A life-threatening poisoning is signified by loss of consciousness, incontinence, convulsions and respiratory depression with a secondary cardiovascular component. Treat symptomatically. If exposed, plasma and red blood cell cholinesterase tests may indicate degree of exposure (baseline data are useful). Atropine, only by injection, is the preferable antidote. Oximes, such as pralidoxime chloride, may be the****utic if used early; however, use only in conjunction with atropine. In cases of severe acute poisoning, use antidotes immediately after establishing an open airway and respiration. With oral exposure, the decision of whether to induce vomiting or not should be made by an attending physician.
NOTE: Product contains a petroleum distillate solvent. Vomiting may cause aspiration pneumonia."

Here is the warning for Malathion:

"KEEP OUT OF REACH OF CHILDREN – CAUTION - POISON – Hazardous if swallowed, inhaled, or absorbed through skin. Avoid breathing spray mist or

WARNING STATEMENTS:
NOTE TO PHYSICIAN: This product is an organophosphate (cholinesterase-inhibiting) insecticide. Atropine is antidotal and should be given in multiple doses as
necessary until the patient is atropinized. In severe cases 2-PAM may be given provided therapy begins within 24 hours of exposure. Monitor serum and
RBC cholinesterase. Administer intravenous fluids cautiously, if needed, to correct dehydration. Symptoms of cholinesterase inhibition include salivation,
gastrointestinal hypermotility, abdominal cramping, nausea, diarrhea, sweating, miosis, tearing, blurred vision, headache, dizziness, ataxia, bradycardia,
dyspnea, cyanosis, and muscle twitching or tremors. In extreme cases, tetany, mental confusion, incontinence, weakness, collapse, paralysis, convulsive
seizures, and even death, can occur.

4. FIRST AID MEASURES
If swallowed: Call a poison control center or doctor immediately for treatment advice. Do not give any liquid to the person. Do not induce
vomiting unless told to do so by a poison control center or doctor. Do not give anything by mouth to an unconscious person.
If on skin or clothing: Take off contaminated clothing. Rinse skin with plenty of water for 15-20 minutes. Call a poison control center or doctor for
treatment advice.
If in eyes: Hold eye open and rinse slowly and gently with water for 15-20 minutes. Remove contact lenses, if present, after the first 5
minutes, then continue rinsing eye. Call a poison control center or doctor for treatment advice.
If inhaled: Move person to fresh air. If person is not breathing, call 911 or an ambulance, then give artificial respiration preferably by
mouth-to-mouth, if possible. Call a poison control center or doctor for further treatment advice.
NOTE TO PHYSICIAN: This product may cause cholinesterase inhibition. Atropine is antidotal. 2-PAM may be effective as an adjunct to Atropine.
Vomiting may cause aspiration pneumonia."

"Repeated Dose Toxicity
For the active ingredient(s): Excessive exposure may produce organophosphate type cholinesterase inhibition. Signs and symptoms of excessive exposure to active ingredient may be headache, dizziness, incoordination, muscle twitching, tremors, nausea, abdominal cramps, diarrhea, sweating, pinpoint pupils, blurred vision, salivation, tearing, tightness in chest, excessive urination, convulsions. In animals, effects have been reported on the following organs: Adrenal gland. Dose levels producing these effects were many times higher than any dose levels expected from exposure due to use. Solvent has been reported to cause liver, kidney and blood effects at high exposure levels. For the major component(s): In animals, effects have been reported on the following organs: Respiratory tract. Cataracts were observed in rats exposed to cumene vapors.
Chronic Toxicity and Carcinogenicity
Active ingredient did not cause cancer in laboratory animals. For the minor component(s) Cumene. Has caused cancer in laboratory animals. However, the relevance of this to humans is unknown."

If pure undilute Lorsban were the spill... then much more of a concern. I assume this was diluted to spray solution for field app. when loaded into the Aircraft.
