Neck injuries among electric utility workers, 1995-2007
The aim of this study was to describe the incidence and impact of neck injuries among electric utility workers. Rates of neck injuries per 10,000 employee-years were calculated for various demographic and occupational factors using data from an injury surveillance database established among 17 electric utility companies over the period 1995-2007. The overall rate of neck injuries was 13.3. Male workers had a slightly higher rate than females, and younger workers (<30) had the highest neck injury rates. Trade/craft workers experienced the highest rates of neck injuries, whereas office-based experienced the lowest. The majority of neck injuries (69%) were sprain/strains, and resulted in less than one lost day of work (76.7%).

Etiology of work-related electrical injuries: A narrative analysis of workers' compensation claims
Workers' compensation claims routinely collected over a one-year period from a large U.S. insurance provider were used to identify electrical-related injuries. Among the 586,567 reported claims during 2002, electrical-related injuries accounted for 1283 (0.22%) of nonfatal claims and 15 fatalities (1.2% of electrical). Most (72.3%) were male, average age of 36, working in services (33.4%), manufacturing (24.7%), retail trade (17.3%) and construction (7.2%). Body part(s) injured most often were the hands, fingers, or wrist (34.9%); multiple body parts/systems (25.0%); lower/upper arm; elbow; shoulder, and upper extremities (19.2%). The leading activities were conducting manual tasks (55.1%); working with machinery, appliances, or equipment; working with electrical wire; and operating powered or nonpowered hand tools. Primary injury sources were appliances and office equipment (24.4%), wires, cables/cords (18.0%), machines and other equipment (11.8%), fixtures, bulbs and switches (10.4%) and lightning (4.3%). No vector was identified in 85% of cases, and the work process was initiated by others in less than 1% of cases.

Etiology of work-related electrical injuries: A narrative analysis of workers' compensation claims
The objective of this study was to provide new insight into the aetiology of nonfatal, work-related electrical injuries. A multistage, case-selection algorithm was developed to identify electrical-related injuries from workers' compensation claims and a customized coding taxonomy to identify pre-injury circumstances. Workers' compensation claims routinely collected over a 1-year period from a large United States insurance provider were used to identify electrical-related injuries using an algorithm that evaluated injury cause information, nature of injury, accident description and injury description narratives. Concurrently, a customized coding taxonomy for these narratives was developed to abstract the activity, source, initiating process, mechanism, vector and voltage. Among the 586,567 reported claims during 2002, electrical-related injuries accounted for 1283 (0.22%) of nonfatal claims. Data on these accidents are broken down by sex, age, sector of activity, body part injured, type of activity and source of electricity.

Electrical accidents
Accidents dus à l'électricité [in French]
The occurrence of electrical accidents increased strongly along with the growth in domestic and industrial uses of electricity during the 20th century. The pathological effects of an electrical current passing through the body vary. Life-threatening incidents, extensive burns and trauma require dedicated and pluridisciplinary support. The coordination of first aid is a key step in this process. The meeting or otherwise of certain goals during the first few hours of hospitalization determine the success of future outcomes. Essential steps include ensuring haemodynamic stability and controlling hypovolaemia, acute myoglobinuric renal insufficiency and trauma extension, while initiating the local or surgical treatment. Prognosis is initially difficult, given that the extent of injury is often not visible. Sequelae can be serious and invalidating.

A new electromagnetic exposure metric: High frequency voltage transients associated with increased cancer incidence in teachers in a California school
In 2003, the teachers of a school in California complained of an abnormally high incidence rate of cancer. The objective of this study was to investigate the cancer incidence among these teachers, and its cause. A retrospective study of cancer incidence in the teachers' cohort was investigated in relationship to the school's electrical environment. Sixteen school teachers among the 137 teachers working at the school from 1988 to 2005 were diagnosed with 18 cancers. The observed to expected (O/E) ratio for all cancers was 2.78, while the O/E ratio was 9.8 for malignant melanoma, 13.3 for thyroid cancer end 9.2 for uterine cancer. A positive relationship was found between cancer risk and cumulative exposure to high frequency voltage transients on the classroom's electrical wiring. It is concluded that high frequency voltage transients may be a universal carcinogen, similar to ionizing radiation.

Protecting against arc flash hazards
In 2005, 250 workers died in the United States after coming into contact with an electrical current, often the result of an arc flash occurring from equipment that had not been de-energized before repair or maintenance work began. Most, if not all, of these deaths could have been prevented by ensuring that workers use fire-resistant personal protective clothing, are properly trained and adopt safe practices such as de-energizing or isolating high-voltage equipment.

Electrical accidents in Germany
Elektrounfälle in Deutschland [in German]
The report on electrical accidents in Germany includes industry and trade, leisure and household accidents. It is based on several sources of data, including insurance institutions, criminal investigation divisions, forensic medical institutes, regional statistical offices and the Federal Statistical Office. Statistics are published since 1926, when it was believed that a rate of more than 400 fatal accidents/year had to be accepted, and extend to 2003, with 67 fatalities. All analyses show that the causes for electrical accidents in the recent past are primarily found in human error. This includes errors in handling and operation of electrical equipment and systems, improper repairs and poor maintenance. Other findings are discussed. (2002 Edition, see 02-891).

60-Hertz electric-field exposures in transmission line towers
This study investigated 60-Hz electric field exposures among line workers in 230 to 765-kV transmission line towers. The exposures were based on computations of the unperturbed electric field along climbing routes and at work positions on the towers and on insulated ladders suspended in towers. Computed exposures are generally expressed in terms of the unperturbed electric field averaged over the body surface as stipulated by guidelines. However for realistic on-tower positions, the worker's posture, the uniformity of the field, and the field orientation differ from the guideline exposure scenario of standing erect in a vertical uniform field. The average electric-field exposure during climbing ranged from 10kV/m for a 230-kV tower to 31kV/m for a 765-kV tower, occasionally exceeding the 20kV/m limit given in the recently adopted IEEE Standard C95.6 2002.

Causes of electrical deaths and injuries among construction workers
This study evaluates electrical deaths and injuries to construction workers based on two sources of data: 1,019 electrical deaths identified by the US Census of Fatal Occupational Injuries for the years 1992 to 1998, and 61 electrical injuries identified between November 1, 1990 and December 31, 1998 from a George Washington University Hospital Emergency Department database. Contact with "live" electrical wiring, equipment and light fixtures was the main cause of electrical deaths and injuries among electrical workers, followed by contact with overhead power lines. Among non-electrical workers, contact with overhead power lines was the major cause of death. Other causes included contact with energized metal objects, machinery, power tools and portable lights. Adoption of a lockout/tagout standard for construction and training for non-electrical workers in basic electrical safety would reduce the risk of electrical deaths and injuries in the construction industry.

Safety procedures for work carried out in junction boxes of prefabricated electrical cable ducts
Procedimientos de seguridad para trabajos en cajas de derivación de canalizaciones prefabricadas para la distribución de la corriente eléctrica [in Spanish]
Prefabricated electrical cable ducts represent a safety guarantee to workers, but they also involve certain hazards. In order to avoid serious accidents that may have fatal outcomes, it is therefore highly important that workers be aware of the hazards related to each type of task to be carried out, and that clear procedures be defined . This article describes safety procedures that apply to the various tasks carried out in junction boxes of prefabricated electrical ducts.

CIS 08-433 Controlling electrical hazards
Electricity has long been recognized as a serious workplace hazard, exposing employees to electric shock, electrocution, burns, fires and explosions. In 1999 for example, 278 workers died from electrocutions at work, accounting for almost five percent of all on-the-job fatalities that year in the United States. This safety guide on controlling electrical hazards addresses the following topics: OSHA electrical safety standards; basic facts about electricity (flow through conductors and through water, causes of shocks, effects of shocks on the body); protection against electrical hazards (types of insulators, guarding, grounding); training of personnel; programmes and services proposed by OSHA.

Prevalence of self-reported hypersensivity to electric or magnetic fields in a population-based questionnaire survey
The aim of this study was to estimate the prevalence of self-reported hypersensitivity to electric or magnetic fields in the general population and to describe characteristics of the group reporting such hypersensitivity with regard to demographics, other complaints, hypersensitivities and traditional allergies. A cross-sectional questionnaire survey was conducted in 1997 among 15,000 men and women between 19 and 80 years of age in Stockholm county. The response rate was 73%. One and a half percent of the respondents reported hypersensitivity to electric or magnetic fields. Prevalence was highest among women and in the 60-69 age group. The hypersensitive group reported all symptoms, allergies and other types of hypersensitivities included in the survey to a significantly greater extent than the rest of the respondents.
