Sensitivity of electric detonators to static electricity
Čuvstvitel'nost' ėlektrodetonatorov k ėlektrostatičeskim zarjadam [en ruso]
Granular explosives are often transported and loaded into boreholes by pneumatic means; this can produce static electric charges on the explosive and on the pipes, hoses and rock through which it moves, and poses a threat of premature detonation, especially when detonators are being placed. To model possible situations, charged capacitors were connected to one lead of detonators. The voltage and charge of the capacitors and the connections and grounding of the detonators were all varied; 13 configurations were tested. The minimal energy required for detonation (110mJ) was observed when one end of the capacitor and one lead were connected and the other end of the capacitor and the other lead were grounded; energies required for detonation in other configurations were much higher. It is very unlikely that electrostatic energies of such magnitudes will be built up under underground conditions. Not placing detonators in boreholes until loading is completed will add an extra measure of safety.

Electrostatic capacitance of the human body relative to the ground
Die elektrostatische Kapazität des menschlichen Körpers gegen Erde [en alemán]
In the introduction, the significance of the electrostatic capacitance of the human body in medicine, technology and occupational safety is emphasised, and test results published by 34 authors are reviewed. Differences between results are explained by the influence of various factors (heights, posture, shoes, ground, humidity, static and dynamic behaviour). The results of new tests confirm this variation as a function of the individual. Generally, however, an electrostatic capacitance of 100-300pF is measured.

What is the reason for the difference in the biological effect on the heart of direct and alternating current?
Worauf beruht der Unterschied in der biologischen Wirksamkeit von Gleichstrom und von Wechselstrom am Herzen? [en alemán]
Ventricular fibrillation is more easily induced by alternating than by direct electric current. Alternating current can also mimic the effects of autonomic stimulation. The different effects of the 2 types of current are due to the fact that alternating current acts like a series of impulses, whereas direct current acts like a pulse only at the moment of switching on or off. The relation of these phenomena to the basic mechanisms of cardiac excitation and fibrillation is discussed.

Leukaemia in workers exposed to electrical and magnetic fields
The Cancer Surveillance Programme, a population-based registry that collects information on incidence cases of cancer in Los Angeles county (USA), was reviewed for leukaemia cases in men who were listed as having jobs with exposure to electric or magnetic fields. For white males between 1972 and 1979 there was a trend towards increased proportional incidence ratios for all leukemias, and the risk was greatest for acute myelogenous leukaemia. The excess risk was significant for power and telephone linemen. Other shared exposures in these occupational groups may also contribute to this risk.

Electrical accident hazards for firefighters in the use of water guns in the vicinity of high-voltage installations
Die Gefährdung des Löschpersonals beim Einsatz von Wasserwerfern im Bereich von Hochspannungsanlagen [en alemán]
Tank-truck mounted water guns, used more and more frequently by firefighters, may be the cause of electrical accidents when fires are being fought in the vicinity of high-voltage electrical installations. If the water jet is aimed at a high-voltage or even low-voltage installation whilst the insulated motorised pump is short-circuited by a low-impedence body (e.g. a human body), a leakage current flows back to the voltage source via the earth. A description is given of trials carried out on 110 and 220kV installations, aimed at measuring the leakage current in relation to the distance from the source. Types of nozzle that should be used are discussed.

Elektriske felt i høyspenningsanlegg - En kartlegging av elektriske felt under kraftledninger, i fordelingsanlegg of i kraftstasjoner [en noruego]
Sections cover: physics of electrical and magnetic fields; instruments and methods for measuring field intensity; results. These show that electrical field intensities, measured 1.8m above ground under overhead lines, depend on the voltage level, the height of the lines above ground and the type of pylon. Field intensity may be as high as 6kV/m in the case of a 420kV line 11.5m above ground (the natural atmospheric electrical field intensity being only 0.13kV/m). Intensity falls exponentially with increasing line height. Measurements at 1.8m above the ground in 420 and 300kV substations showed maximum intensities of 11kV/m and 6.4kV/m at a distance of 2.5m from the disconnecting switches.

The main causes of accidents in the construction of high-voltage overhead electricity distribution lines are listed (handling at ground level and at heights, movements of workers at heights, direct and indirect electrocution). Guidelines are proposed for reducing hazards at the pylon design stage: construction from factory prefabricated components; assembling the components on the ground; lifting into position by rotation on a hinged base; built-in safe acces facilities to the top of the pylon; where possible, the structure should be lifted into place with the insulators and wire pulleys already in position; where feasible, use of aluminium components to reduce the weight of the structures handled. Proposal and description of an "X" tripod structure that meets these criteria. Diagrams of the phases in pylon assembly.

Cytogenetic and gonadotoxic action of a static electric field
Citogenetičeskoe i gonadotoksičeskoe dejstvija statičeskogo ėlektričeskogo polja [en ruso]
The widespread use of polymeric materials (textiles, construction materials, plastics) under conditions which promote the accumulation of static electric charges means that workers may be exposed to unnaturally high fields. To determine the effects of static fields, mice were subjected to static electric fields up to 700V/cm in intensity for 2h, after which testicular tissue was examined for chromosomal aberrations. 700V/cm produced both chromosomal aberrations and reduced spermatogenesis; 300V/cm had similar but less pronounced effects, while 150V/cm produced no changes. Thus, 300V/cm is a threshold exposure level.

Edelstahlfasern in textilen Filtermedien als Schutz gegen Explosion durch elektrostatische Aufladung bei der Trockenfiltration [en alemán]
Following a review of minimum ignition energy requirements for dust/air mixtures, the article defines conditions for the prevention of ignition by electrostatic discharge. Textile filters incorporating stainless steel fibres meet these safety requirements. Description of tests on this type of filter: conductivity and corona discharge capability. The corona effect ensures continuous discharge and prevents spontaneous discharge and sparking which may cause explosions.

Ignition of dust/air mixtures by static discharges
Entzündung von Staub/Luft-Gemischen durch Entladungen statischer Elektrizität [en alemán]
Factors conditioning various types of discharge (lightning-like and brush discharges) and the relevant energy levels are reviewed. Research is described on minimum energy levels required to ignite dust/air mixtures. In view of the difficulties of this type of research, the practical value of the results for explosion prevention purposes is questioned.

Fault arc detection within flameproof enclosures
An electrical fault arcing across certain plastic insulating materials within a flameproof enclosure can render traditional flameproof protection ineffective. Discussion of the problem and description of a solution which has recently been developed. Experiments with several devices (light, smoke, heat and pressure detectors) showed that a bi-metal, bi-stable thermostat was the most suitable, small, simple, reliable and cheap device to apply a low level of earth leakage to one phase to cause the back-up protection to trip out, thus preventing ignitions in flameproof enclosures. Table of tripping times for this thermal detector (arc current 400A, open circuit voltage 400V, arc power 120kW).
