EXCEPTION: The use of approved insulating gloves or
						  insulated tools or other protective measures are not required when working on

						  qualified person that there will be no employee exposure to electrical shock,
						  electrical burns, explosion or hazards due to electric arcs.
(A) Rubber insulating gloves shall meet the
						provisions of the American Society for Testing Materials (ASTM) D120-09,
						Standard Specification for Rubber Insulating Gloves, and be maintained in
						accordance with ASTM F496-08, Standard Specification for In-Service Care of
						Insulating Gloves and Sleeves, which are hereby incorporated by reference.

						  retests shall not exceed 6 months for insulating gloves and 12 months for
						  insulating sleeves and that insulating gloves and sleeves that have been
						  electrically tested but not issued for service shall not be placed into service

						following types of fabrics, either alone or in blends, unless the employer can
						demonstrate that the fabric has been treated with flame retardant: acetate,
						nylon, polyester, and rayon.
