Liquids having conductivities between these values are . If the air is dry enough, a difference in electrical potential or “ charge” can occur. Some common nonconductive liquids are listed in nFPA (Annex B – table B.2) . Figure (bottom) shows the recommended system. Responses to FAQs are prepared by NFPA technical staff to assist users in reading and understanding NFPA codes and standards. The responses, however , are not Formal Interpretations issued pursuant to NFPA Regulations.

Practice on Static Electricity. Note 3: For further information on protection against static electricity and lightning hazards in hazardous (classified) locations, see: Hermetically Sealed. Ground Connection Junction Box with. According to the NFPA (Code ), solvents that are soluble in water (or can dissolve some water themselves) do not build up static electricity. However, when liquids are transferred into non-conductive containers (e.g., plastic, glass), even conductive . Any ungrounde conductive objects?
