Controlling Static by managing flow rates

/ Chemical Process Safety (PSM/RMP), Flammable Liquids, Hazardous Materials, OSHA Compliance /

Managing static electricity during the transfer of flammable liquids is based on the fluid’s conductivity, measured in picosiemens per meter (pS/m). High-conductivity liquids dissipate charge quickly, while low-conductivity liquids (static accumulators) hold onto the charge, creating a spark hazard. The following table summarizes the maximum flow velocities recommended by NFPA 77 and API 2003 to…...
