• You will be using scissors, knives, razor blades, and other tools that have sharp edges. Follow these procedures exactly. • Use X-acto knives or snap-off disposable craft knives rather than razor blades. If you must use a razor blade, use only a single-edged blade with a shield. • Dispose of blades properly by wrapping them and taping the wrap shut. If a safety container is provided for sharp objects, always dispose of blades in this container. • Always cut away from you or toward the side.
