Pesticide Safety and your Behavior MONTANA STATE UNIVERSITY PESTICIDE SAFETY EDUCATION PROGRAM 2014 Pesticide Poisoning is common in Montana. 31% of private applicators surveyed have been at least mildly poisoned by exposure to pesticides. Always minimize bad habits while wearing recommended PPE to minimize exposure. Are Montana applicators protecting themselves from Pesticides? Do you wear PPE that is required on the product label while applying pesticides? Wear required PPE while applying pesticides 11% 42% Do not wear required PPE while applying pesticides 47% While applying pesticides, did not know what was on the product label Are their reasons why we may not be protecting themselves? What is the final and 4th mode of entry of pesticides? Mode of Entry Applicators also focus on Acute Toxicity Acute Toxicity Testing is required by the Environmental Protection Agency for: Each active ingredient For inert ingredients Usually uses rats over a short period of time Very expensive process Relates to the signal word. Relates to the LD50 LD50 Lethal dose at which 50% of a given population develops lethal effects Expressed in parts per million You have an LD50 of 100 parts per million with one chemical and a LD50 of 10,000 parts per million with another. Which one is more toxic? 100 parts per million; takes less to produce a toxic effect Signal Words / LD50 Table 2. Signal words found on pesticide labels. Caution (Category IV) You can drink the stuff Signal Word? The focus on only acute toxicity. Agent Orange 1:1 mixture of 2,4-D and 2,4,5-T Produces dioxins – carcinogen The National Toxicology Program has classified dioxins as a human carcinogen, frequently associated with soft-tissue sarcoma, Non-Hodgkin's lymphoma, Hodgkin's disease and chronic lymphocytic leukemia (CLL). Agent White Compound 4:1 mixture of 2,4-D and picloram 1896 – 1985! Did he prove that drinking picloram is not associated with detrimental health effects? No! Not a replicated study Actual dose unknown Did this contain the inert ingredients Didn’t assess delayed or chronic toxicity Don’t judge a book by it’s cover! 1896 – 1985! Chronic Toxicity Long Term Exposure Many repeated low dose exposures Definition EPA mandates testing for chronic toxicity of: Active ingredients Must classify inert ingredients into 1 of 4 categories Usually on rats This is very expensive Chronic toxicity statements are placed on the product label (carcinogen, mutagen, reproductive damage, etc..) Some of our “Safest” chemicals Chronic Affects Evident Immune system problems Sores, Rashes New: Ag. Health Study Participants: 90,000 people Certified Pesticide Applicators and Spouses IOWA: 31,877 farmers 21,771 farm spouses 4,916 commercial applicators NORTH CAROLINA 20,518 farmers 10,567 farm spouses Navigate to http://aghealth.nih.gov/ Respiratory Health Wheezing (airways in lungs are narrowed) associated with… Pesticides (Paraquat, parathion, malathion, chlorpyrifos, atrazine, alachlor, EPTC) Parkinsons Disease and Pesticide Use Applicators have up to twice the risk of Parkinsons Disease Used pesticides more than 400 days in their lifetime. Strongly associated with paraquat use. More bad habits…. 70% of all applicators surveyed removed gloves at some point in their career while repairing spray equipment. 9% never wore gloves to begin with. Did you remove gloves while repairing equipment? 9% 2% 19% 70% Removed gloves while repairing equipment. Wore gloves while repairing equipment. Never wore gloves to begin with. Gloves were not recommended on the product label. Protecting Yourself: How and Why?

Prices: $2 - $8 Respirators NO! YES! Particulate masks (dusts, granules) The one-strap dust mask is not NIOSH approved. When pesticide label recommends a dust filter this is not acceptable. For nuisance-level dusts. Generally, two-strap respirators with exhale valves are not for pesticide spraying but are acceptable for application of pesticide dusts and granules. Always read the pesticide label for product-specific recommendations. Cartridge Type Respirators (pesticide vapors) Fitted face piece and replaceable filters Not for fumigants Prefix of NIOSH/MSHA “TC” Cartridges should be replaced annually and stored in ziplock bags Cartridges usually labeled for use with ORGANIC VAPORS Follow product label Self Contained Breathing Apparatus (SCBA) Manure Pit with methane and hydrogen sulfide Anyhydrous Ammonia Grain Fumigants Special Medical Certification Needed Do your workers need to suit up? Agricultural Use Requirements Conclusion True hazard is a product of toxicity and exposure Understand your products acute and chronic toxicity by reading label. Understand that some pesticides can effect an applicator years after exposure. Minimize exposure! Wear personal protective equipment as indicated on the product label.
