How much static voltage of human body is safe?
The minimum ignition energy of the oil and gas mixture is 0.018mJ, and the human body capacitance in the operation is about 200PF. According to the calculation of the formula E=1/2CV2, the human body voltage at this time is 425V. In other words, when the human body voltage is greater than 425V, the energy of the human body is greater than 0.018mJ, and it is possible to ignite the oil and gas mixture.
Therefore, in dangerous workplaces such as petrochemical industry, the safety value of human voltage should be less than 425V.
Human static alarm detects the static electricity of the human body and alerts when the static voltage exceeds 100V.
