Iowa Right-of-Way Herbicide Category 6 Practice Exam

Using heavy-duty liquid detergent is the recommended method for washing contaminated personal protective equipment (PPE) because it is designed to effectively break down and remove a variety of contaminants, including oils, chemicals, and herbicides that may adhere to the fabric. Heavy-duty detergents contain stronger surfactants that target and lift these residues, ensuring a thorough cleaning.

When dealing with PPE, which may have been exposed to hazardous materials, it's crucial to ensure that these agents are removed completely to prevent exposure or ingestion during future use. A regular household detergent might not be effective enough against these types of contaminants.

Beyond detergent choice, washing techniques such as water temperature and whether to wash with other laundry items also matter greatly. Using cold water is less effective for removing certain types of contaminants. Washing contaminated laundry with regular family laundry poses a risk of cross-contamination, while relying solely on dish soap may not provide the same level of cleaning capability as a heavy-duty detergent. Therefore, the use of heavy-duty liquid detergent is the most appropriate choice for ensuring the safety and cleanliness of contaminated PPE.
