Grounding Points & Static Grounds — what QA looks for

nductivity additive in commonly used aviation turbine fuels minimizes static buildup during fuel flow. Warning: The additive does not eliminate static electricity in fuel flowing through hoses or pipes but rather facilitates releasing the built- up static charge. This is why proper grounding and bonding of fuel systems, components and equipment is necessary to mitigate the ignition risk posed by static discharge. 18.2.3.2. Clothing containing more than 65 percent nylon, rayon, wool, or polyester will not be worn as outer garments when working with or around low flash point fuels. (T-0) 18.2.3.2.1. Flak vests will not be worn during aircraft fuel servicing operations or during fuel operations where low flashpoint vapors may be present. (T-1) 18.2.3.2.2. In all cases, a employee wearing a fl

iation. For this reason, take precaution against performing unnecessary actions that lead to the buildup of static voltages, take action to avoid the prolonged storage of static voltages on personnel or equipment, and take action to discharge static voltages in a safe and controlled manner during operations involving explosives. (T-1) See DESR 6055.09, Edition 1, Change 1, February 23, 2024 VOLUME 2 – ENCLOSURE 3: ELECTRICAL STANDARDS 190 paragraphs V2.E3.4.2. through V2.E3.4.7. for the static grounding and bonding system design and inspection requirements. (T-1) Refer to NFPA 77 and AFMAN 32-1065 for requirements on static grounding and bonding systems. (T-0) V2.E3.4.1. (Added)(DAF) Requirement for Static Grounding. See paragraph V2.E3.4.10. for static grounding techniques and paragraph V

t vapors may be present. (T-1) 18.2.3.2.2. In all cases, a employee wearing a flak vest will always ground or bond themselves when approaching an aircraft and prior to beginning work. (T-1) 18.2.3.2.3. If no spark occurs during bonding or grounding, normal work may begin. However, if a spark does occur during bonding or grounding, the employee will ground or bond themselves frequently during all work phases. (T-1) Commanders may authorize the wear of body armor/flak vests and Gortex-type clothing in combat areas. (T-2) Outer garments will not be removed or put on in the work area. (T-0) Matches or lighters will not be handled or removed from pockets. (T-0) 18.2.4. Sources of Static Electricity. 18.2.4.1. Filter separator vessels generate static electricity when fuel flows through filters.

cations where operations continue or where parking facilities are required on a recurring basis. Where static grounding facilities are not available at a suitable parking location, use the best alternate method of reducing the hazard in the following order or precedence: V2.E3.4.9.2.1. (Added)(DAF) Keep static grounding to 10,000 ohms or less by using grounding rods. (T-1) V2.E3.4.9.2.2. (Added)(DAF) Equalize the static electrical potential between the aircraft and the vehicle or handling equipment used in loading or unloading by bonding them together with an approved static ground wire, cable, or strap (see paragraph V2.E3.4.5.). (T-1) It might not be feasible to bond the handling equipment to the aircraft if the handling equipment must move during the operation. V2.E3.4.10. (Added)(DAF)
