    Chapter 6

  3. Pesticide applicators are legally and socially responsible to safely handle pesticides. Failure to comply with federal and state regulations could result in injury, lawsuits, fines and imprisonment. In the eyes of the law, ignorance is no defense. It is your responsibility to keep current with changing pesticide regulations.
  4. By federal law, the pesticide label is a legal document that must include safety guidelines for use, storage and disposal of the product. Read the label before purchasing the pesticide. Review the label before opening, mixing, or applying the pesticide.
  5. As an applicator you risk of exposure to pesticides is greater than others. It is wise and legally required that you wear personal protective equipment recommended on the label. Purchase and properly maintain PPE. Do not attempt to make do with ill-fitting gear or gear inn disrepair. Frequently wash residues off equipment exposed to pesticides.
  6. You may chose to wear more protective gear than the label requires. This is a good idea if:

    -you are exposed to pesticides on a regular basis, or

    -if you have a naturally-low cholinesterase level.

  7. the Professional Lawn Care Association of America (PLCAA) provides protective equipment guidelines. Note that PLCAA recommendations may be more strict than those on product labels.
  8. PLCAA Protective Gear Recommendations for:

    Filling and Mixing

    Dry fertilizer only: Disposable dust mask or respirator with dust filter.

    Pesticides: Goggles or face shield; head gear; coveralls or apron; boots; gloves; full respirator with dust filter when using powders.

    Hand Cans: Wear gloves for all materials.

  9. PLCAA Protective Gear Recommendations:
  10. During an Application-

    Fertilizer only: Boots; gloves

    Insecticides or liquid

    Slow-release nitrogen: boots; gloves; goggles (when high-pressure spraying)

  11. PLCAA Protective Gear Recommendations for:
  12. Handling Spills:

    Wear all protective clothing and equipment recommended for the material applied.

  13. Cholinesterase is an essential chemical in the nervous system of animals. Cabamate and organophosphate insecticides fatally inhibit cholinesterase in insects. These insecticides also lower the applicator’s cholinesterase. If you are regularly exposed to cholinesterase-inhibiting insecticides such as carbaryl, oxamyl, diazinon, dursban, malathion and acephate you should establish a testing program with your doctor. Determine your normal level of cholinesterase (the baseline level) in the off-season. If your cholinesterase level drops significantly below your baseline, avoid further exposure to insecticides until you have recovered. Many commercial companies have in-house cholinesterase monitoring as part of their safety programs.
  14. The Professional Lawn Care Association of America has developed guidelines for cholinesterase exposure and testing. Consults PLCAA or your doctor for more specific information concerning cholinesterase testing.
  15. Most pesticide poisonings result form accidents, or careless and ignorant use. However, even cautious applicators who follow the label, maintain equipment, and apply pesticides with safety in mind may experience overexposure to pesticides.
  16. Should an accident occur, the best defense against serious harm is to be prepared. You should know at all times what chemical, formulation, and rate you are handling
  17. Have on hand and know how to use first-aid and safety materials.
  18. First Aid and Safety Materials

    *Pesticide label *Change of clothing

    *MSDS *Spill absorbent

    *Syrup of Ipecac *Fire extinguisher

    *First aid kit *Poison control phone number

    *Eye wash *Hospital contact

    *Detergent -phone number

    *Clean water -doctor

    *Extra rubber gloves -directions

  19. being prepared means you need to be familiar with the common pesticide poisoning symptoms. Poisoning symptoms vary with the type of pesticide, type of exposure, the amount absorbed, and the general health of the individual. Be aware that while some symptoms begin immediately upon exposure, others are delayed for several hours or even days.
  20. the symptoms of pesticide poisoning are similar to those of other ailments including heat exhaustion, asthma, and food poisoning. Remember, alcohol intensifies the effect of pesticide poisoning and should be avoided whenever pesticide overexposure is suspected.
  21. Those exposed to pesticides on a regular basis should know the symptoms of poisoning for fungicides, herbicides, and insecticides.

  1. Because of their widespread use and high acute toxicity, organophosphates are responsible for more pesticide poisonings than any other class of pesticides. Small doses of organophosphates "add up" in the nervous system during the spray season and may result in poisoning without obvious symptoms.
  2. An applicator who is ill after handling pesticides is not necessarily poisoned. IF you have poisoning symptoms and believe the cause may be from pesticide exposure, see your doctor. Let you doctor decide if pesticide poisoning has occurred.
  3. First aid treatment is different for each type of exposure. Review the appropriate first aid measures before beginning pesticide applications. There will be little time or opportunity to look up first aid recommendations when you need them. Remember, poisoning symptoms may not be immediately evident. After severe exposure to pesticides, do not put off first aid until you feel bad. First aid is just that- the initial effort to help a victim while medical help is on the way.
  4. When pesticide comes in contact with skin:
  1. When pesticide is inhaled:
  1. If pesticide contacts the eye:
  1. If pesticide has gotten into your moth, but has not been swallowed, rinse thoroughly with large amounts of water. When a pesticide is swallowed, read the label to determine if vomiting should be induced.

30. Never induced vomiting if the:

  1. Victim is unconscious.
  2. Victim is convulsing.
  3. Pesticide is formulated with petroleum products.
  4. Pesticide is corrosive.
  5. Label specifies not to induce vomiting.

31.Do not waste time inducing vomiting—get to the hospital.

32. Preventing mishaps when applying pesticides is the most effective way to protect yourself, nontarget organisms, and the environment.

33. Routine inspections and maintenance of equipment will prevent common accidents such as blown hoses and leaking tanks. Routinely inspect application equipment and the truck and trailer. Once a problem is detected, do not take repair "short cuts".

34. Mixing and loading concentrates are some of the most hazardous activities involving pesticides. Before opening the pesticide container, review the label and put on personal protective equipment.

35. Do not eat, smoke or chew gum while mixing. Mix in an area that has plenty of light and ventilation, but is protected from winds. Never leave the filling spray tank unattended. And, as always, follow label directions.

36. You must prevent contamination and back-siphoning into the water source while filling. Do not allow the water pipe or hose to come in contact with spray solution. Fill-station pipes should be fitted with a back-siphoning valve.

37. Measure pesticide concentrates accurately and mix only what can be used during the day. Rinse measuring tools and put rinse water into the spray tank. Triple rinse or power rinse pesticide containers as you empty them.

38. Properly rinsed pesticide containers are non-hazardous. Studies have shown that at least 14.2 grams of active ingredient remains in an empty, unrinsed 5-gallon container. While 14.2 grams seems insignificant, 25,000 unrinsed containers contains 780 pounds of active ingredient! As the bar graph shows, even one rinse greatly reduces residue in the container, and the third rinse essentially eliminates residue.

  1. What happens to the pesticide you applied? Ideally, all of the pesticide applied is in place, and completely breaks down after pests are controlled. Unfortunately, even when used properly, some pesticide will have undesirable effects.
  2. Pesticides may harm thatch decomposers and other beneficial organisms in turf. This compromises the pesticide application by reducing natural pest control and turf vigor. Be aware of the potential impact of pesticides on people, pets, the applicator, and wildlife as well.
  3. Almost every insecticide used on turf is highly toxic to fish, waterfowl, and songbirds. Wildlife exposed to pesticides may outright die, or any suffer form illness and reproductive failure. Wildlife, and people, are indirectly exposed when they eat food contaminated with pesticides. Even today, trout in the Great Lakes have one billion times more DDT in their bodies than can be found in the surrounding water.
  4. Since most turf stands are in areas frequented by people, it is especially importatn for Category 3A applicators to be safety conscious. People depend upon you to protect them, their children and pets from pesticide spray and residue.
  5. Before the application carefully inspect the targeted and nearby areas. Be sure to check over fences. Have clients close house windows and move cars out of the spray area. Remove from the area, cover, or wash off tay, swing set and other play equipment, pet dishes, swim gear, small pool, hanging laundry, bird feeders, bird baths and ornamental fish ponds. Beware of food plants near target plants. Before leaving the property, be sure to inform clients about the reentry period.
  6. Application equipment is attractive and highly dangerous to children. Do not leave operating equipment unattended, even for a short break. Equipment that is no in use must be stored in a safe and secure manner.
  7. Storing hazardous materials poses a great potential for liability. Limit the amount of pesticides stored through careful planning and application.
  8. It is good policy to inform your local fire department about your facility. Because chemicals you are storing. Check with Michigan Department of Natural Resources or MSU Extension about SARA Title III requirements.

47. There are numerous guidelines for establishing a safe, secure pesticide storage area. To summarize the guidelines provided in the core manual exterior pesticide storage includes:

  1. The interior of a well-designed pesticide storage facility includes:
  1. Know that pesticide storage regulations may change and that it is your responsibility to learn about and comply with new regulations. Contact the Micihan Department of Agriculture or MSU Extension for assistance.

50. Safety guidelines for pesticide containers include:

  1. - Securely reseal or bag opened pesticide containers.

  1. Improper disposal of pesticides can cause environmental damage, and health risks to humans. Limit the amount of pesticide waste you create by adopting these practices:
  1. Pesticide wastes are classified as hazardous. Contact Michigan Department of Natural Resources (now DEQ), about the legal responsibilities of pesticide disposal.

54. Pesticide spills include any amount of concentrate that may escape as you mix, a leaking container, or an overturned spray rig. Your goal is to promptly and effectively:

  1. Applicators are expected to conduct themselves professionally and with safety consciousness. In 1990-91, the Michigan Department of Agriculture created Regulation 637 as a response to public concern over commercial pesticide applications. Regulation 637 governs the following work of commercial applicators:

- Spray contacts -Drift management

- Integrated pest management -Use standards

- Protective gear -Mixing and loading

- Notification registry -Washing equipment

Obtain a current copy of Regulation 637 and understand what you must do to comply with Michigan law.

  1. Being an experienced, or even a certified, applicator does not make you a professional. In addition to being knowledgeable about turfgrass, pests, and pesticides, you must:
  1. Clients often equate gallons of pesticide sprayed with your value as an applicator. Help the clients realize that your knowledge and monitoring skills are valuable services.
  2. For successful turf management, you must help clients understand the importance of proper watering, mowing and fertilizing practices. As a professional applicator you will spend part of your workday explaining and answering questions. It can be a difficult task, but help clients to understand that:
  1. Most insects, fungi, etc. are not pests!
  2. Turfgrass cannot be both pest-free and benefit from natural controls.
  3. There are specific times to implement pest management tactics. Outside of this window, management efforts are wasted.

  1. #4. Turf must be regularly inspected for damage and to determine the best timing for various management tactics.
  2. 5. Apply pesticides selectively. Often only limited areas of turf require treatment.

    6.Pesticides are by no means the only and best method of pest management.

  3. Because most pesticide application problems are within the control of the applicator they are best resolved by improving operational practices. Be educated, up to date, and safety conscious – be a professional pesticide applicator.
