Which statement is true about opening pesticide containers?

Using a sharp knife or scissors to open paper or cardboard containers is the appropriate method because these tools are designed to safely cut through the material without causing spills or creating hazardous situations. It allows for a clean and controlled opening, minimizing the risk of accidentally puncturing a container, which could lead to spills or splashes of the pesticide. Additionally, using dull or inappropriate tools can increase the risk of injury or contamination.

The other options suggest unsafe practices. For example, using a hammer to force open containers can lead to breakage and create a hazardous environment due to potential exposure to the pesticide. Shaking the container before opening can also be inadvisable, as it may cause the contents to become agitated, increasing the risk of spills upon opening. Lastly, pulling apart plastic containers with your hands can be equally risky, as excess force might cause breakage or spray contents, potentially causing harm or exposure. Thus, option C is the safest and most effective choice for opening pesticide containers.
