Tips for Avoiding Pesticide Poisoning

Tips for Avoiding Pesticide Poisoning

April 9, 2010

When handling pesticides, be cognizant of how to protect yourself, children, pets, and wildlife. Always follow label instructions on how to properly mix and load, apply, or store pesticides and what personal protective equipment (PPE) is required.

Unfortunately, despite these precautions, accidents do happen and you should be aware of how exposure can occur and the toxicity of the product you are using, and be prepared to handle a potential pesticide emergency. For more information, consult EC2505, Managing the Risk of Pesticide Poisoning and Understanding the Signs and Symptoms. Procedures and contact information that should be used in the event of accidental exposure or poisonings are also listed on the label.

Routes of Pesticide Exposure

Pesticides have three main routes of exposure, or ways in which they can enter the body. These include

  • dermal (through the skin or eyes)
  • oral (through the mouth)
  • inhalation (through the lungs)

Toxicity Signal Words

Labels reference precautions for pesticides, such as “Poisonous if swallowed, inhaled, or absorbed through the skin.” They also provide signal words to indicate relative toxicities of pesticides to humans. Signal words include

  • Caution (low toxicity)
  • Warning (moderate toxicity)
  • Danger (high toxicity)

Choosing a pesticide with lower toxicity reduces the likelihood of being exposed to enough pesticide to cause signs or symptoms.

In some cases, pesticides themselves have fairly low toxicities, but are often mixed with surfactants or other ingredients that increase the toxicity of the product.

Pesticide Storage

Reducing the potential for poisoning not only includes properly using pesticides, but also properly storing them. Always keep pesticides in their original containers and out of reach of children. Store pesticides away from your home, grain bins, or livestock barns. For more information about storing pesticides, consult EC2507, Safe Transport, Storage, and Disposal of Pesticides.

Pesticide Poisoning

Learn to recognize signs and symptoms of pesticide poisoning, such as nausea, vomiting, sweating, dizziness, or pin point pupils. See EC2505 and Recognition and Management of Pesticide Poisonings  for examples of these and other signs and symptoms. In case of accidental exposure or poisoning, contact your local medical provider, emergency numbers provided on the label, or the nearest Poison Control Center (1-800-222-1222). Identify the responsible pesticide and make its label available to the medical personnel treating the poisoning victim.

Remember, if you have been working with pesticides, do not automatically assume that flu-like or other symptoms are due to other causes. When in doubt, see a doctor!
