Faulty behaviour as a factor in electrical accidents
Fehler im Verhalten als Ursachen für Unfälle durch elektrischen Strom [in German]
Analysis of 30,000 electrical accidents at work (of which 724 were fatal) reported between 1971 and 1981, with 90% of the accidents occurring while using low-voltage equipment. The neglect of the 5 main rules of electrical safety was the main cause of accidents in 45% of the cases, while faulty behaviour in general was the main cause in 33% of the cases. Detailed analysis of these 2 groups of causes follows, with an attempt at explaining faulty behaviour, very often a result of inappropriate work organisation. In most cases electrical safety rules are respected during work, with unsafe behaviour occurring particularly after work and after work interruptions. Technicians tend to ignore safety instructions. Other influencing factors are age and seniority.

Occupational exposure to electromagnetic fields and the occurrence of brain tumors
Epidemiologic study based on death certificates of 951 white male Maryland (USA) residents who died of brain tumour in the period 1969-1982. Compared with the controls, the men employed in electricity-related occupations were found to experience a significantly higher proportion of primary brain tumours. An increase in the odd's ratio for brain tumours was found to be positively related to electromagnetic field (EMF) exposure levels. Furthermore, the mean age at death was found to be significantly younger among cases in the presumed high EMF exposure group. These findings suggest that EMF exposure may be associated with the pathogenesis of brain tumours, particularly in the promoting stage.

Health of workers exposed to electric fields
There were no statistically significant correlations of health with measured or estimated exposure to electric fields by 390 electrical power transmission workers. The study involved health questionnaire interviews, long-term estimates of their exposures to 50Hz electric fields and short-term measurements of actual exposure for 287 of the workers (averaging approx. 30kVm-1h over a 2-week exposure period). Significant correlations were found between health measures and job categories, geographical regions, overtime, working alone, and frequently changing shifts.

Possibility of dangerous voltage build-up in secondary circuits of welders' power supplies
O vozmožnosti opasnogo summirovanija naprjaženij vo vtoričnyh cepah svaročnyh istočnikov [in Russian]
When two welders use different power supplies (one AC, one DC), or when two power supplies of the same type are connected in opposite polarity, the use of a common ground by the two welders yields a voltage between the two electrodes that is twice the voltage between either electrode and the workpiece; the voltage can be as much as 180V. Where two or more welders are at work on a project that provides a common ground, special instruction and inspection should be provided to make sure that all power supplies are of the same type and are connected with the same polarity.

Increasing electrical safety in the use of flexible excavator cables
Povyšenie urovnija ėlektrobezopasnosti pri ėkspluatacii gibkih ėkskavatornyh kabelej [in Russian]
26.4% of all high-voltage electrical accidents in excavations during the period 1969-1981 involved cables. The most common cause of injury from current or arcing was erroneous supply of power to a disconnected but ungrounded cable. Injuries occurred most often during the disconnection and reconnection of cables during normal operation of equipment. (Percentages of other causes and circumstances are listed.) 70% of the injuries were attributable to failure to use safety devices (insulating gloves, portable grounding systems, voltage detectors, etc.). The safety situation can be improved by: assuring the supply and use of safety equipment; using plug-type connectors instead of junction boxes; introducing improved shielded cables and circuit breakers.

Survey of electric and magnetic fields at Ontario hydro VDU work stations
This research report describes the methodology and instrumentation used in measuring electric and magnetic fields produced by VDTs at 54 different workstations. The frequency range investigated went from d.c. to a.c. beyond 1MHz. At 30cm from the VDT, the maximum equivalent environmental d.c. field was 1500V/m and the electric and magnetic fields at 17kHz were respectively 2.7V/m rms and 0.16A/m rms. These levels are thought to be too low to present a biological risk to the operators.

Contact lenses: no extra risk for welders
Contactlenzen geen extra gevaar bij lassen [in Dutch]
In 1983 arc welders and industrial physicians were alarmed by statements on accidents resulting in blindness in contact-lens wearers who looked at electric arcs. These statements were totally unfounded as were similar stories that had been published on several occasions since 1971. The results of recent research on the effects of welding arcs on rabbit eyes covered with contact lenses provide no contraindication for contact-lens wearers.

Spraying of liquids under high pressure results in a cloud of electrostatically charged droplets. The conditions under which discharges occur, and under which explosive vapour-air and gas-air mixtures ignite during cleaning operations inside containers, were studied. The liquids involved included water, xylene, and toluene. Safe container sizes, pressure levels and liquid flow-rates were established. The ignition risk increased when solid impurities were found in the liquids.

Interference with the pacemakers of two workers at electricity substations
2 case studies of electrical engineers with pacemakers, who experienced pacemaker dysfunction (competitive rhythm in one case, inappropriately slow pacing in the other) when working near high-voltage electric lines (range 132-400kV). A protective suit that would prevent this kind of electromagnetic interference is described. In addition, there is a recent report of improved circuitry in pacemakers, which would lead to an electronic elimination of the interference.

Ozone and leukaemia. Is there a causal relationship?
Evidence that ozone is radiomimetic and may be the cause of an excess of leukaemia found in certain occupational groups (electricians, electronic technicians, linemen, television and radio repairmen, and motion picture projectionists) is presented. These workers are all exposed to electrical or magnetic fields but they are also exposed to ozone originating from electrical discharges which occur in these working environments.
