A review of the factors influencing electrostatic shocks in offices
Abstract
Electrostatic shocks are relatively rare in Britain. The key factor is the electrical resistance of the carpet which is a function of the material, the weave, and the relative humidity of the ambient air. Relative humidities above 40% or 55% when underfloor heating is used will prevent most shocks. Lower humidities can occur during cold spells in nonhumidified buildings which have air conditioning or mechanical ventilation. In this case the shocks will be more likely to occur in the large open plan offices when walking distances are large. Women are much more sensitive than men. Electrostatic sparks from people will not ignite dust clouds, but can ignite common flammable gases. Particular attention is needed in oxygen enriched atmospheres since a spark which would be unnoticed could ignite gases in such an atmosphere.
