Which statement about the proper technique for opening pesticide containers is true?

Using a sharp knife or scissors to open paper or cardboard containers is the correct technique because it ensures a clean and safe opening, minimizing the risk of spilling or splattering the pesticide inside. Proper tools help maintain control and reduce the chance of accidental exposure to the chemicals. Additionally, this method helps avoid damage to the container that could lead to leaks or contamination, which is critical in ensuring both safety and efficacy when handling pesticides.

In contrast, donning personal protective equipment (PPE) after opening the containers is not advisable because it leaves the handler potentially exposed during a critical time when handling hazardous materials. Leaving a container open while mixing pesticides can increase the risk of contamination, spills, and accidental exposure, creating safety hazards. Lastly, shaking a container before opening is generally not recommended, as it may cause the contents to expand and potentially leak or spray upon opening, which could result in exposure or inhalation of pesticide residues.
