The U.S. Environmental Protection Agency, or EPA, estimates that over 500 million pounds of herbicides were used in the United States in 2000. The concerns regarding overexposure to herbicides are valid. Several factors determine the toxicity of herbicides including the concentration and type of active ingredient, the method of application and the kind of protection worn by the person using the herbicide. Before using any herbicides, carefully read the product's label and material safety data sheet. These documents provide concise information regarding treatment options.
Dilute the Herbicide
In cases of skin exposure, the National Pediculosis Association recommends washing the victim's skin with water, using soap and water. You may need to wash the skin several times to remove all of the herbicide residue. You should also remove any clothing that came in contact with the herbicide. If a rash or redness persists, consult your doctor for further treatment.
Rinse the Eyes
Drift from spraying herbicides can affect your eyes, especially if you are not wearing eye protection. In case of accidental exposure, rinse your eyes with water for several minutes. The FMC Corporation recommends that you continue rinsing your eyes for 15 minutes. If you experience any type of irritation, seek medical attention.
Induce Vomiting
With some herbicides, you can induce vomiting to treat some cases of accidental ingestion of herbicides. You can do so by administering an emetic such as ipecac or simply by sticking your finger down your throat. To avoid breathing issues, bend over at your waist.
Bear in mind, this is not a treatment for all herbicides. You should not induce vomiting after overexposure to some products such as those containing chlorpropham. This is why it is essential to be familiar with any first aid measures before you need them.
Use an Antidote
Fortunately, you can treat some cases of overexposure to herbicides with an antidote. In cases of accidental ingestion, you may be able to give the victim activated charcoal after vomiting, explains the University of Missouri Cooperative Extension. Activated charcoal will help adsorb the toxin until you can get medical assistance. However, if the victim is unconscious, do not attempt to give him any liquids.
Seek Medical Attention
With some herbicides such as paraquat, there are no specific antidotes you can administer to treat overexposure, advises Ramapo College of New Jersey. In these cases, you should call 911 immediately. The poison control center can provide further instructions. Knowing the name of the herbicide will speed treatment.
