Published on: November 2, 2017
Summary
Street lighting electrocutions, often involving old metal poles and wet conditions with 480-V power, pose significant risks. Identifying these common factors in electrical accidents can inform safer equipment design.
Area of Science:
- Electrical engineering
- Public safety
- Occupational health
Background:
- Street lighting systems, particularly older installations, can present electrical hazards.
- Understanding the specific conditions leading to electrocution is crucial for accident prevention.
Observation:
- A review of five electrocution cases (four fatal, one nonfatal) linked to street lighting equipment.
- Common factors identified include aged installations, metal poles, wet environments, 480-V power sources, and intact fuses.
Findings:
- The consistent presence of specific environmental and equipment factors in electrocution incidents.
- The intactness of fuses suggests the failures were not due to simple overcurrent protection.
Implications:
- Recommendations for redesigning street lighting to mitigate electrocution risks.
- Improved safety standards and maintenance protocols for electrical infrastructure.
- Enhanced awareness among electricians and the public regarding electrical hazards in public spaces.

01:11Electric Charges
From lightning during thunderstorms to electronic devices, the phenomenon of electromagnetism is all around us. The electromagnetic force is one of the four fundamental forces of nature. It has been known to humanity in various forms for thousands of years. For example, the ancient Greek philosopher Thales of Miletus recorded his experiments on static electricity using amber and fur in the sixth century BC.

01:16Equipotential Surfaces and Conductors
For a conductor in which all charges are at rest, the conductor's surface is equipotential. The electric field is always perpendicular to equipotential surfaces. Therefore, in a conductor with static charges, the electric field just outside the conductor is always perpendicular to the conductor's surface. Any tangential component of the electric field will cause charges to move inside the conductor, which will violate the electrostatic nature of the system. In an electrostatic situation, if a...
01:10Electrical Energy
Using electric appliances for a longer period of time consumes more electrical energy and results in a higher electric bill. The energy produced by the transfer of electrons from one point to another is known as electrical energy. If power is delivered at a constant rate, the electrical energy can be defined as the product of power used by the device for a period of time. The energy unit on electric bills is the kilowatt-hour, where one kilowatt-hour is equivalent to 3.6 × 106 joules. The...
01:13Household Wiring And Electrical Safety
Companies that supply power to most modern households use three conductors, typically called a three-wire line. While one is neutral, the other two are both at 120 V but with opposite polarity, giving a voltage of 240 V between them. With a three-wire line, high-power appliances that require 240 V, such as electric stoves and clothes dryers, are linked between the two hot lines. 120 V appliances can be connected between the neutral and either of the hot lines. The neutral side, which is always...
01:23Insulation Coordination
Insulation coordination is the process of matching electric equipment's insulation strength with protective device characteristics to protect the equipment against expected overvoltages. This selection is based on engineering judgment and cost. Equipment can generally withstand short-duration high transient overvoltages, but repeated tests with identical waveforms can yield inconsistent results. As a result, standard impulse voltage waveforms are used for testing, defined by specific times for...
01:30Electroconvulsive Therapy
Electroconvulsive therapy (ECT), or shock therapy, remains a critical biomedical intervention for severe, treatment-resistant depression. While its origins can be traced back to Hippocrates' observations that malaria-induced convulsions alleviated mental illness, modern ECT has evolved significantly from its earlier, more primitive applications. First introduced in 1938 by Ugo Cerletti and his colleagues, ECT involves inducing controlled seizures using electrical currents. In its early years,...
