Hyderabad: Greatly helpful if used in the right way, electricity can be equally dangerous in case of oversight. As the second wave continues to rage the country, hospitals are flooded with patients. With round-the-clock use of ventilators, air conditioners and other appliances, the power systems in hospitals face massive overload, leading to electrical hazards.
Failure to comply with standards prescribed in Article 517 of the National Electrical Code (NEC) is also a cause of these accidents. On the directive of the Central Electricity Board, the Electrical Department is going to organize an Electrical Safety Week from May 1 to 7 to inculcate safety consciousness.
Electricity is the lifeline of modern society. One-tenth of an ampere of electricity can kill a human being in seconds. According to the National Crime Records Bureau (NCRB), there have been 22,442 electrical accidents in India in 2019, in which 13,432 people died. Of these, 908 happened in Andhra Pradesh and 735 in Telangana. In addition, another 1,990 people lost their lives due to short circuit incidents.
On average, 43 people are exposed to electrical hazards per day. It is disturbing that most of them are farmers and manual workers. The Central Electricity Authority (CEA) estimated that 15 animals die every day in electricity accidents.
16 patients and 2 nurses were killed in a recent accident at a hospital in Bharuch, Gujarat. Since August, 93 people were killed in fire accidents across 24 hospitals in the country.

Most of the deceased were COVID-19 patients. All these accidents have taken place over the past two months. Hospitals and medical fraternity are overburdened during the current second phase. Overworked ventilators and increase in the number of ICU beds is also becoming a risk factor.
The wiring system in the hospital should be set up as planned during the construction phase itself. The main power supply wires must be connected to all floors through special route. Transformers and generators should not be near patient rooms under any circumstances. A special transformer without voltage fluctuations should be installed in the operation theatres.
Rooms with critical cases should have an alternate power supply. Appropriate training should be given to medical staff on how to use all types of testing equipment. High-load devices such as AC, geyser that run continuously should be monitored daily. Due to the shortage of electrical engineers in most of the hospitals, there are no effective inspections. Many of the chemicals used in hospitals are highly flammable.
Even a small spark can result in major fire accidents. Such hazardous elements or oxygen cylinders should not be kept near panel boards. The government is setting up makeshift hospitals in public areas. In such places, accidents are occurring due to inadequate wiring systems.
Use of faulty electrical equipment, negligence and self-repair are the major causes of electrical accidents. Excess load on wires and bad connections are few other causes. Governments should ban equipment that does not meet quality standards during the production phase. Consumers should only buy ISI-certified equipment. The service wires from electric poles should directly be connected to the meters. An earthing pit must be set up close to the meter.
An earth leakage circuit breaker (ELCB) must be installed near the main supply. Appliances such as motors, AC, geysers, refrigerators and mixers should be used with three-pin sockets alone. Farmers should use ISI compliant motors and starters. They need to make sure that water pipes do not touch the power lines. Power fencing should not be used for agricultural lands or animal traps.
During natural calamities like heavy winds, floods or cyclones, one should not go near wires, poles or transformers. People should consult expert staff in case of electric outages or repairs.

No constructions should be undertaken or bore wells are dug near electric wires. Electric wires can be seen at arm’s length in towns and cities. Appropriate precautions should be taken when moving heavy vehicles in city lanes. Flying kites should be banned in residential areas. Government should raise awareness on the use of electrical appliances among people.
The Electrical Department is going to organize an Electrical Safety Week from May 1 to 7 to inculcate safety consciousness among people and working staff. Accidents can be easily avoided if equipment manufacturers, field-level staff of electricity companies, industrial workers and consumers adhere to safety standards.
Power distribution companies must ensure that LT and HT lines are at least 19 feet high. They should be set up at least 4 feet away from trees and buildings. Transformers should be installed at a height of 6 feet to meet quality standards.
In residential areas, a fence must be set up around transformers. Hanging wires, rusty and outdated poles must be monitored and replaced from time to time. Field staff should be available to attend to repairs and electric outages. Electricity personnel should check for the earthing system before working on the electric lines.
