What Are the Dangers of Using Cypermethrin?
Cypermethrin, a pesticide first synthesized in 1974, targets insects by acting on the central nervous system, according to the National Pesticide Telecommunications Network (NPTN). Because the substance is designed to be toxic, taking measures to ensure safe use when working with it is absolutely essential.
A Designed Killer
Cypermethrin belongs to a family of pesticides called pyrethroids. The NPTN reports that cypermethrin was designed to be chemically similar to pyrethrins, a substance in an extract from the chrysanthemum plant called pyrethrum.
In the Environment
According to the International Labor Organization (ILO), cypermethrin is highly toxic to fish and other aquatic organisms.
Flammability
Because the chemical is generally provided in pesticide formulations in organic solvents, the ILO warns that pesticides containing cypermethrin tend to be combustible and that open flames near the pesticide should be avoided.
Toxic Fumes
In the case of a fire, as temperatures climb above 220 degrees Celsius or 428 degrees Fahrenheit, cypermethrin will decompose to produce highly toxic gases, including hydrogen cyanide and hydrogen chloride, according to the ILO.
Normal Use
The ILO also advises that symptoms of acute, short-term exposure to cypermethrin may include irritation to the skin, eyes and respiratory tract, in addition to effects on the nervous system including tingling, itching or burning sensations in the face. Ingestion of the substance can cause abdominal pain, convulsions and vomiting.
Protecting Yourself
As with any pesticide or chemical, safe use and handling is paramount. Because the body can absorb the substance by inhaling or ingesting it, the ILO advises that the substance only be used in a well-ventilated area. Moreover, people exposed to the substance must use appropriate personal protection equipment including a popper mask with face shield and protective gloves and clothing.
