Provides recommendations relating to safe control of electrostatic charges generated incidentally by processes or activities. Its purpose is to assist in reducing fire, explosion and nuisance aspects associated with static electricity. It outlines conditions under which the presence of static causes a hazard and recommends methods for its safe dissipation or mitigation. Appendices provide information about the hazards caused by static electricity in the vicinity of flammable mixtures, on minimum ignition energies for a range of chemicals and give examples of solving problems resulting from static electricity.
Scope
This Standard sets out recommendations for controlling static electricity (hereinafter referred to as 'static') which may be generated incidentally by processes or activities and which may present hazards, damage or inconvenience.
Considerations relating to the generation of static and the problems it presents in a given environment are given, together with a description of methods and equipment for measuring electric potential, charge, capacitance and resistance parameters associated with electrostatically charged objects. Specific control methods are given for some industries.
The provisions of the standard should not be regarded as overriding statutory requirements, but may be construed as working recommendations to be used in conjunction with such requirements.
Methods for minimizing the risk of static causing a fire or explosion arising from the use of flammable medical agents are not included, as they are given in AS 1169. Similarly, methods for affording protection from lightning are not included, as these are given in AS/NZS 1768, nor does this standard include the earthing systems of patient treatment areas in hospitals and the like.
NOTE: Examples of the solving of some practical problems resulting from static are given in Appendix A.
