Do not use this type of mat to protect yourself from electrical shock. Many customers have, near their equipment, rubber floor mats that contain small conductive fibers to decrease electrostatic discharges. Some hand tools have handles covered with a soft material that does not insulate you when working with live electrical currents. Use only approved tools and test equipment. Observe the following rules when working on electrical equipment. Do not obstruct fan louvers or cover them with labels or stickers.
