It seems that everything has a cord attached to it. This can be problematic if you are operating a device in an area where people are moving from one are to the next. It is important to keep people safe from tripping over these cords.
7 Always secure your cord. If a person seriously injures themselves by tripping over your cord, you will be legally liable. Never underestimate a person's ability to not see something. That brightly colored cord with fluorescent reflective stripes on it may seem impossible to miss to you, but someone somewhere will manage to miss it.
Tape the cord to the floor with duct tape. Once again, this isn't practical if the cord will only be there for a short while. This will leave a sticky residue on the cord, which can be removed with damp melamine foam.
