These requirements cover electrically conductive floorings of the completed or finished type intended for use in hospital operating rooms, arsenals, and other locations where it is necessary to avoid the accumulation of static electricity.

These requirements do not cover slip-resistance characteristics of electrically conductive flooring.

These requirements do not cover electrically conductive equipment and materials for use in flammable anesthetizing locations.

Although certain cleaning operations are necessary to maintain the inherent conductivity of a flooring, these requirements do not cover floorings which require periodic application of solutions or coatings to produce the required conductivity.

Requirements for the installation and use of electrically conductive floorings are included in Chapter 12 of the Standard for Health Care Facilities, NFPA 99.

Additional requirements for the installation of ceramic tile floorings are included in the Specifications for Electrically Conductive Ceramic Tile Installed with Conductive Dry-Set Portland Cement Mortar, ANSI A108.7.

A product that contains features, characteristics, components, materials, or systems new or different from those in use when the Standard was developed, and that involves a risk of fire, electric shock, or injury to persons, shall be evaluated using the appropriate additional component and end-product requirements as determined necessary to maintain the level of safety for the user of the product as originally anticipated by the intent of this Standard.
