Electrical Safety: Causes Of Unsafe Electricity

The leading cause of accidents at work with electricity is related to negligence. That is failure to comply with recommended electrical safety procedures. Among the specific factors from that lead to accidents, we can mention:

  • Incorrect use of equipment due to lack of qualification or care
  • Use of equipment and tools for tasks other than those for which they were designed
  • Use of damaged equipment or tools
  • Performing tasks on equipment that is not disconnected from the electrical current
  • Incorrect use of PPE (personal protective equipment)

Now we know the main risks and causes related to the lack of security in electricity. At this point, you may be wondering what the parameters are for working safely in electricity.

All the guidelines for working safely in electricity are in NR 10 – Safety in Electricity Installations and Services.  

The objective of NR 10 is precise to guarantee safety and health to workers who carry out installations and services in electricity.

NR 10 establishes, for example, control measures for electrical work. There are three main risk control measures in electrical installations:

  • Collective protection measures
  • Individual protection measures

Work Procedures

It should be noted that, in most cases, the measures are complementary to electricity safety. In other words, safety in electricity results from measures taken together. In addition, NR 10 requires documentation and certifications that prove the performance of such electrical safety measures and devices.

NR 10 also determines safety measures in projects and the construction, assembly, operation, and maintenance of equipment. Likewise, it establishes guidelines for safety in de-energized and energized electrical installations.

Choose the right tools: don’t improvise using tools for purposes other than those for which they were designed;

Prioritize the quality of the project: project professionals must indicate conditions that will be carried out and used in the installations, the design of cabling, and the installation of safe electrical panels.

Maximum attention to detail: when de-energizing the electricity sources, the professional takes the main precaution to guarantee their safety in electricity;

Invest in training: always try to be up to date with the requirements of NR 10 and other relevant regulatory standards, such as NR-35. Visit to learn more.


Working with electricity doesn’t have to be complicated. Just follow the guidelines of NR 10 and ensure that the projects meet the relevant NBRs.
