How much electrostatics is there when you are fueling?

- According to the actual measurement, the electrostatic voltage has far exceeded the safe value (500 V), and violent discharge will occur when touching metal objects.
How
much electrostatics is there when you are
fueling?
Welcome
to ALPTEC electrostatic laboratory!
Testing Method: The conductive wrist strap is connected with
FMX-003 Electrostatic
Field Meter and FMX-003 is
connected with the grounding stud,
it will show the personal real-time electrostatic voltage.
Testing environment:
Temperature: 19.5℃; Humidity: 34.8%
01.How
much electrostatics can people generate who wearing sweater when they get off
the car?
Conclusion:
The
personal electrostatic is up to 11.2kv, and it is still above 5kv after
standing. It will generate strong static electrostatic
discharge when touching metal or door.—It is very dangerous!
02.How
much electrostatics can people generate who wearing different materials clothes
when they get off the car?
Wearing
pure cotton coat:
The maximum electrostatic voltage is up to 8.1kv.
Wearing pure down jackets：
The maximum electrostatic voltage is up to 11.1kv.
Wearing pure woolen coat：
The maximum electrostatic voltage is up to 10.4kv.
The
video of the whole process of the above test.
Conclusion:
The
electrostatic voltage of warm clothing is all over 10000 V! The electrostatic
generated by different materials of clothing is different. According to the
actual measurement, the electrostatic voltage has far
exceeded the safe value (500 V), and violent discharge will occur when
touching metal objects.
03.How
much electrostatic can be generated when close to
charged objects after discharging electrostatic?
The body
instantly induces 2kv electrostatic when close to the seat carrying electrostatic
after eliminating static electricity.
Conclusion:
The
personal electrostatic is generated in an instant. Even if the electrostatic
discharge is completed, when the human body is close to the seat or clothes
carrying electrostatic, it will instantly generate up to several thousand
volts of induced electrostatic, and a violent discharge will occur when it
touches a metal object.

04.What
does 11kv electrostatic discharge look like in slow motion?
Note:
The test video was recorded outdoors during the day, and the spark could not be
captured.
The
discharged energy not only has a great risk of ignition, but also a strong
stimulation of human nerves, which can easily lead to secondary accidents.
Under
ordinary clothes, the generation of electrostatic is fast, and the voltage is
higher than we can imagine. It may be a simple action that can generate
electrostatic up to several thousand volts. The existence of this dangerous
electrostatic seriously threatens safe production.
Electrostatic is not visible. Only when spark discharge occurs can you know
whether there is dangerous electrostatic.
Electrostatic
needs to be seen and monitored to ensure the safety of electrostatic in a safe
place.
After
many years of independent research and development in ALPTEC, the research
achievements of Electrostatic Monitoring Eliminator can implement the detection
of electrostatic in the space. Once electrostatic is found to exceed the
dangerous value, it will immediately alarm the personnel to eliminate
electrostatic!
