What is Electrical Safety? 

Electrical Safety is the technical measures put in place to prevent harmful and dangerous electrical hazards on workers and equipment that may arise from electrical surges and mishaps. 

Electrical Safety can also be defined as the precautionary measures observed to prevent harmful and dangerous electrical effects on employees and equipment such as electric shocks, electrocution, injuries, explosion, fire outbreak and many others. 

We rely on electricity on most of our day to day activities, but sometimes underestimate its capability of causing injury. Some of the serious injuries you can receive from electricity include electrical shocks, electrical burns, and electrocution, which could be fatal. 

Electrical Safety Precautions can protect against all types of electrical shocks and burns. Safety precautions could be different for the home and for the workplace, depending on the electrical devices being dealt with.


Electrical Safety Basics

Most electrical devices pose a higher threat to life because of their high voltage and high electrical power in nature. So you must take further safety precautions and know safety basics when dealing with these devices.

Below are Electrical Safety basics you need to know:

1. Do not use exposed conductors holding 50 volts or more.

2. Ensure electrical equipment is properly connected, grounded and in good working order.

3. Do not use extension cords as permanent wiring and should be removed after temporary use for an activity or event.

4. Equipment with high amperages such as space heaters, portable air conditioners, and other equipment must be plugged directly into permanent wall receptacles.

5. Do not use or alter any building's electrical service, including circuit breaker panels, unless you are specifically qualified and authorized to do so.

6. Beware of wet environments because it can increase the risk of an electrical shock.

7. Avoid touching any electrical wire without safety gloves, even if the wire seems safe and insulated. Also, ensure you have your footwear, your footwear must also be safe.

8. Always note the safety precaution manual, and check for all the safety equipment before coming in contact with electrical wires or devices. 

9. Always perform a brief inspection if you are working on a power station to look for possible threats and eliminate them before beginning work.


Advantages of Electrical Safety: 

Some of the advantages of Electrical Safety include: 

1. It provides safety and confidence in our homes and workplaces. 

2. It helps employees understand the types of electrical hazards, how they occur and the proper precautions required to handle electricity and electrical devices. 

3. It reduces the chances of the explosion, injuries or death in electrical environment.

4. It helps to mitigate the danger of electricity, especially in industrial areas by providing workers with the right practices and exposures in dealing with electricity and electrical devices. 

5. It reduces the cost of equipments insurance and maintenance.

6. It helps to easily detect electrical faults.

7. It creates job opportunities for electricians.

8. It creates self-employment opportunities.


Causes of Electrical Hazards: 

The following are some of the causes of electrical hazards: 

1. High Surge from Power Station Supply 

2. Over-loading of Electrical Lines and Devices  

3. Liquid Exposures  

4. Faulty or Inadequate Wiring 

5. Faulty Electrical Devices 

6. Faulty Transformers 

7. Short Circuit 

8. Mishandling of Electrical Devices and Machineries  

9. Faulty or Damaged Insulations 


Electrical Safety Devices: 

1. Fuse: A Fuse is an electrical device that has the capability to protect an electric circuit from excessive electric current. 

2. Circuit Breaker: Circuit breakers are electrical devices that protect circuits from overload current conditions. 

3. Ground Fault Circuit Interrupter: A ground fault circuit interrupter is an electrical device designed to detect any tiny mismatch in currents, going into and out of the circuit, in order to prevent electrocution. 

4. Surge Protectors: Surge protectors are electrical devices designed to protect our homes and appliances against sudden spikes in electrical current. 


Why Electrical Safety? 

Electrical Safety offers lightning and earthing protection systems which are essential for protection of humans, structures and protection of properties from destruction caused by lightning effects and associated risks of fire, transmission lines, electrical equipment shocks and unexpected high current surge or voltage. 

Electrical Safety offers insulation systems which are essential for protection against direct electric shocks from positive wires and high tension cables.

Electrical Safety standards are developed by various government and agencies. They are targeted towards the quality of electrical products that are sold worldwide. In most markets, it is mandatory for electrical products to conform to safety standards promulgated by safety and standard agencies. To conform to Electrical Standards, the product must pass certain safety test such as: 

1. High Voltage Test (also called as Dielectric Voltage, Withstand Test or High Potential Test),

2. Insulation Resistance Test, 

3. Ground (Earth) Bond Test, 

4. Ground Continuity Test, 

5. Leakage Test, 

6. Earth Leakage Current Test, 

7. Enclosure Leakage Current Test. 

In the Full course, you will learn everything you need to know about Electrical Safety with Diploma Certificate to showcase your knowledge.
