Use a box cutter safely.
The FACTS: What you need to KNOW
The Actions: What you need to DO
Check the box cutter and make sure it has the right blade installed correctly. It must be sharp and free from rust or corrosion. The blade should be retractable.
Before cutting, make sure you are stable and balanced and the cutting path is clear. Draw the knife away from your body. Reposition the box or make two cuts if you can't reach.
When cutting thick material, make two or more passes. Don't use more pressure, or the knife might slip.
Retract the blade as soon as you are done cutting and set it in a safe place. Don't set it down or carry it with the blade exposed. Don't hold it when performing a task that requires both hands, like typing.
