SECTION 380:50-23-2. Asbestos-containing duct tape abatement requirements

  Because of the low potential hazard of removing asbestos-containing duct tape while wet, removal of this tape may be done using the following procedures:

(1)   The tape may be removed only by a licensed asbestos abatement contractor, using only licensed asbestos abatement workers.

(2)   Workers shall wear a protective suit, gloves, and at a minimum, a full-face air purifying respirator. Workers may put on a clean disposable suit over the one being worn, and walk to the next area of tape to be removed. The outer suit may be removed during the work, and used repeatedly for walking either to other tape removal areas, or to a convenient shower at the end of the work period.

(3)   Tape on air handling equipment or ductwork may be removed only while the air handlers are off.

(4)   The tape may be removed only from areas that are unoccupied at the time and have critical barriers established.

(5)   The area under the tape is to be covered with a 6-mil poly drop cloth.

(6)   The tape is to be saturated with a wetting agent. Detergent-based residential type cleaning agents may be used.

(7)   The tape is to be peeled away and dropped into a properly labeled asbestos disposal bag.

(8)   The surface under the tape is to be cleaned with a cloth soaked in wetting agent, and the cloth then placed in the asbestos disposal bag.

(9)   The drop cloth is to be rolled or folded and placed in the asbestos disposal bag.

(10)   After drying, the area under the tape is to be sprayed or brushed with paint, varnish, shellac, or other sealant. Care should be taken with flammable sprays.

(11)   Passive air monitoring in the area after tape removal shall be done. Clearance levels shall be 0.01 fibers per cubic centimeter, or the background level, whichever is higher.
