Abstract This article taken from the author's "Industrial Hazard and Safety Handbook" (published by Newnes-Butterworth) considers the hazards of static electricity, how it is formed during some processes (removal of dust from gases, some paint spraying and printing processes) and the phenomena it causes (mainly ignition hazards, but also unexpected shocks in humans, false readings of sensitive instruments, deposit of dust in unwanted places). The author considers the natural build up of static electricity (flow of products in pipes, splash filling, friction from belts, tyres, agitators) and describes some typical accidents (explosions in hospital operating theatres, in oil tankers). A mathematical formula for the electrical quantities involved is given, with a description of methods of protection against static (earthing and bonding, increasing conductance of floors, footwear, wheels, etc., increasing conductivity of non-conductors, ionisation), methods for measurement of electrostatic charge, special ignition hazards and precautions (gas discharges, flammable liquids, combustible powder handling), electrostatic paint spraying, and electrostatic dust removal in printing.
