Electricity safely in the work routine 

First of all, it is essential to understand what electricity is. She is like an invisible river flowing through the wires, full of energy and potential. But, just like a river, if we don't respect its characteristics and power, it can be dangerous.

Electricity is everywhere these days: lighting our homes, playing our favorite music, and even keeping our food fresh. 

However, as a good friend who can sometimes surprise you, it is crucial to know how to deal with her with respect and knowledge.

Safety first

When we talk about electricity, safety is the keyword. After all, a small oversight can cause a big “ouch!”

However, to avoid accidents, we need to know the risks. Electricity, like a sneaky cat, can strike when we least expect it.

Do not overload sockets: Imagine a party where everyone wants to dance in the same small area. It's a disaster waiting to happen, isn't it?

Be careful with water: Electricity and water are like oil and water – they don't mix well. An electrical appliance in the water is an invitation to danger.

Bare wires are hidden enemies: They are like serpents waiting in the dark. Keep them out of reach and replace them quickly.

Protective equipment

Furthermore, protective equipment is our allies. They are like superheroes, always ready to save us. Always use them, without exception.

Preventive maintenance

Eventually, the best way to avoid problems is prevention. Just as we take care of our health, the health of our electrical systems also needs attention.

Regular check-ups

Inspection of wires and equipment: Periodically, like a doctor doing a check-up, check the condition of the wires and equipment.

Systems updates: Similarly, just as we update our cell phones, electrical systems also need updates to ensure safety and efficiency.

Educating for Safety

On the other hand, education is a powerful tool. Teaching children and adults about the dangers and safety measures related to electricity is essential.

Family and school dialogues: Promote conversations about electrical safety. It's like planting a seed that will grow strong and healthy.

Professional training: For those who work with electricity, training is essential. It's like a shield against invisible dangers.

Frequently asked questions about safe electricity for electricians’ routine 

NR-10, a specific regulatory standard for safety in electrical installations and services, is essential for electricians. 

It establishes guidelines and procedures to ensure the safety and health of workers who interact with electrical installations. 

Furthermore, NR-10 covers everything from professional qualification requirements to control measures and preventive systems, ensuring that occupational risks are minimized.

But there are other very common questions, see below. 

How to identify and prevent electrical risks in the workplace?

To identify electrical risks, the electrician must carry out a detailed assessment of the environment, considering aspects such as the condition of the equipment, the presence of exposed wiring and the humidity of the location. 

Preventing these risks involves keeping equipment and tools in good condition, using appropriate PPE and strictly following safety procedures. 

Furthermore, it is essential to stay up to date on safe practices through regular training and updating technical knowledge.

What Personal Protective Equipment (PPE) is essential for electricians?

Essential PPE for electricians includes electrical insulating gloves, safety glasses, hard hats, insulated shoes and flame-retardant clothing. 

This equipment protects against electric shocks, electric arcs and other risks associated with working with electricity. 

Furthermore, it is crucial that PPE is regularly inspected and maintained in good condition, ensuring its effectiveness and compliance with safety standards.

How important is safety signage in places with electrical risks?

Safety signage is vital in places with electrical hazards. It serves to warn of dangers, advise on safe procedures and delimit risk areas. 

Furthermore, good signage contributes to the prevention of accidents, informing both electricians and other people present about the necessary precautions. 

Signage must comply with technical standards and be clearly visible and legible, something you also learn from the NR10 course

What to do in case of an electrical accident at work?

In the event of an electrical accident, the first action is to turn off the power source, if possible. You should then immediately call the emergency services, providing clear information about the situation. 

While waiting for help, providing basic first aid, if qualified, can be crucial. Furthermore, it is important not to touch the victim if they are still in contact with the electrical source, to avoid the risk of electric shock.

What is the ideal frequency for reviewing electrical installations?

Periodic inspection of electrical installations is essential to prevent accidents and ensure safety. Generally, it is recommended that this review be carried out annually, but it may vary depending on the intensity of use and environmental conditions. 

Additionally, after any significant repair or modification to the electrical system, a new inspection should be performed to ensure everything complies with safety standards.

How can technology help with electrical safety?

Technology is a great ally in electrical safety. Tools such as thermography can identify points of excessive heating, indicating potential electrical failures. 

Additionally, maintenance management software helps monitor and control maintenance activities, ensuring that no inspection or replacement is overlooked. 

Technology also facilitates access to information and training, keeping professionals up to date on best security practices.

How to stay up to date with electrical safety standards?

Staying up to date with electrical safety standards is crucial. Attending courses, seminars and workshops is a great way to stay informed about the latest updates to security standards and practices. 

Additionally, professional associations and specialized publications are great sources of up-to-date information. The internet also offers a wide range of educational resources, including online courses and discussion forums.

What are the consequences of not following electrical safety standards?

Failure to follow electrical safety standards can have serious consequences, including accidents with serious or even fatal injuries. 

In addition to the risk to life and health, failure to comply with standards can result in legal and financial penalties for the professionals and companies involved.

Furthermore, neglecting security can lead to a loss of customer trust and damage to professional reputation.

What role does communication and training play in promoting electrical safety?

Effective communication and ongoing training are key to promoting electrical safety. Training helps ensure that all professionals are aware of risks and safe practices. 

Additionally, clear communication about safety procedures and policy changes ensures that staff are always informed. A well-trained and informed team is less likely to make mistakes that can lead to serious accidents.


In conclusion, dealing with electricity safely is a combination of respect, knowledge and caution. 

Just as a lighthouse lights the way for ships, safety practices light our way in everyday life, ensuring we can enjoy the benefits of electricity without taking unnecessary risks. 

Therefore, let's embrace these practices and make safety a habit in our lives!
