Files are usually provided with ampules.
The top half of the ampule should be in your dominant hand, and the bottom half should be in your non-dominant hand. If there is a painted dot on the top half of the ampule, this is the pressure point. You should place the thumb of your dominant hand directly on top of this dot. If there is no dot, place the center of your thumb pad slightly above where the top of the ampule begins to curve in towards the neck.
Make sure you break it at least a few feet away from your other materials and anything you don’t want to risk getting broken glass on.
If a sharps container is available, you can dispose of the unwrapped ampule in the sharps container instead. If the ampule contains biohazardous materials, it should not be thrown in the trash. Put it in a labeled biohazardous waste container and follow your city’s guidelines for disposing of the container.
Do not throw the ampule in the trash if it contained biohazardous materials. You will have to dispose of it in a labeled biohazardous waste container and follow your city’s guidelines for disposing of the container.
