obtained from suppliers. However, in such a case,
existing charges are only slowly reduced depend-
ing on the shoes that the personnel wear. For per-
sonal safety, the resistance of floor to ground
should not fall below 10

ohms.

The humidity at the installation site should not
fall below 45% relative humidity. High air humid-
ity is a decisive factor in preventing the formation
of electrostatic charges. For example, a relative
humidity of 10 - 20% will produce 35,000 V when
crossing a carpet. This value drops to 1,500 V with
a relative air humidity of 65 - 90%.

Clothing where cotton material is >50%.

Conductive seating.

ESD shoes that can be obtained from suppliers and
are used on conductive flooring help further to
reduce charges when walking across floor cover-
ings.
