Abstract: A static charge equaliser having electrical, physical and dimensional properties such that when interposed between two bodies having different electrostatic charges and which are brought into contact or close proximity, the electrostatic interaction between the two bodies may be affected such that the formation of an undesirable spark between the two bodies is reduced or eliminated, whilst permitting the potential difference between the two bodies to be reduced or eliminated relatively quickly. The static charge equaliser comprises a material having a surface resistivity and/or a volume resistivity and/or dielectric properties such that charge from an approaching charged body is passed through and/or over the equaliser without an undesirable spark discharge.
