11 Electrical safety tips you should follow at all times

Electrical safety is a top priority for electricians. The right precautions can prevent serious injuries and deaths, so make sure you take these 11 steps when working on a residential or commercial electrical project.

1. Deenergize systems before performing any work

OSHA’s electrical standards always stress de-energizing electrical circuits before electricians start working on them. There are only three exceptions to this rule: life-support equipment, emergency alarm systems, and hazardous area ventilation equipment.

In all other cases, electrical outlets and circuits over 50 volts need to be de-energized and the device must be placed in an electrically-safe work condition before an electrician performs any work. NFPA 70E lists six steps that must be followed to ensure an electrically safe work condition:

  1. Determining all possible electrical supply sources by looking at blueprints, diagrams, and ID tags
  2. Disconnect every available source of electrical power by interrupting the load current using appropriate measures
  3. Double check whether all blades of disconnected devices are fully open and drawout-type circuit breakers are disconnected completely
  4. Apply proper lockout/tagout procedures for all devices and equipment as per the documented or established policies
  5. Use a voltage detector to check whether the electrical circuit and phase conductors are de-energized
  6. If there is a chance of induced voltages or stored electrical energy, use ground fault circuit interrupters to de-energize them

2. Follow proper lockout/tagout (LOTO) protocols

The lockout/tagout procedures in electrical work are very crucial to the safety and well-being of people working on site. A proper lockout/tagout (LOTO) procedure must cover these eight steps outlined by OSHA.

According to OSHA, every place with industrial machinery requires a proper lockout/tagout program, and all electricians must have the correct lockout tagout equipment.

3. Perform electrical hazard analysis on all circuits above 50 volts

Before electricians start working on an electrical circuit with an energy of 50 volts and higher, it is mandatory to perform a thorough electrical hazard analysis. The NFPA 70E article specifies that all types of electrical hazard analysis (Shock, Arc-Flash, Arc-Blash, and Burns) must be performed on the electrical circuit.

4. Apply appropriate warning labels to all equipment

Once the electrical hazard analysis is complete, electricians must make the effort to affix appropriate warning labels on equipment. This particular safety standard was added to NFPA 70E in the year 2000. Later on, around 2002, NEC came up with a standard to specify shock and Arc-Flash hazards with a clear warning label.

5. Get proper certification to work on energized equipment

In addition to being trained on the equipment, hazards, and electrical safety precautions, electricians need to get “qualified” to work on energized equipment. NFPA 70E clearly states that a detailed energized electrical work permit must be obtained by the electrician before he/she can work on energized equipment.

These permits help supervisors or managers (who are the signing authorities) to understand the additional risks involved in working on energized circuits. These work permits don’t merely ensure that the worker is qualified for the job but also shift the decision to work on energized equipment from the electrician to the management.

6. Prepare exhaustive job briefs and plans

When working on or near exposed, energized electrical conductors and circuit parts it is important to have a job briefing before electricians work on energized or near-exposed circuits or electrical equipment.

A proper briefing must include:

  • A discussion on potential electrical hazards associated with the task
  • Procedures or tasks that need to be completed during the job
  • Special precautions that must be taken while working
  • Instructions on where and how to remove the source of energy
  • Details on emergency response and communication modes
  • A list of required personal protective equipment (PPE)

7. Wear proper protective clothing

Appropriate personal protective equipment (PPE) must be selected based on specific tasks and hazard levels. While OSHA 1910.173 provides valuable information on the maintenance of PPE kits, NFPA 70 E offers a wealth of insights on selecting the right PPE kit for a job.

In order to meet OSHA and NFPA 70E guidelines, electricians must wear minimum flame retardant clothing, safety goggles, and protective gloves when they work on or approach an energized circuit. Protective insulating blankets or mats can be used to minimize the exposure further. NFPA standards state that PPE kits need to be repaired, cleaned, or washed as per the manufacturer’s instruction prior to every use. Also, PPE kits must be inspected thoroughly before and after a job.

8. Make sure there is adequate lighting

When electricians are working, they must ensure that there is adequate lighting to illuminate their work environment. Portable lights should be fully insulated so as not to accidentally cause short circuits when used near power lines or other equipment which may create electromagnetic fields.

9. Use protective barricades or barriers around hazards

The use of barriers during electrical work is key to preventing the injury of unqualified individuals. Barricades can be used for any type or size job, and they warn children and adults living close to the potential hazard.

The cabinet doors of electrical panels should always be closed. The panels should never have holes; this helps prevent the exposure of live wires. If any electrical panel cannot be closed, there should be barriers, shields, or other insulating materials around it.

10. Be prepared for the unexpected

Electricians must not only be trained and knowledgeable about their line of work but also be familiar with emergency procedures. All electrical workers must be aware of emergency communication methods and have trained medical personnel ready when working on potentially hazardous electrical tasks.

Preparation is the key to ensuring electrical safety. Before an electrician works on a task, they should consider what could go wrong and plan accordingly . When they are prepared to face the worst, they can mitigate and overcome any challenge that is ahead of them.

11. Use protective devices wherever possible

Current-limiting devices reduce the potential for electrical hazards by limiting how much current can flow through them. Here are some benefits of using current-limiting overcurrent protective devices:

  • They reduce the voltage on circuit boards thus eliminating the chance of short circuits
  • They prolong device life by limiting the current level through parts that may be quickly heated up
  • They prevent shocks from occurring when you are working near live electrical wires
  • They also act as an anti-surge measure

Electrical safety standards and regulatory organizations

Today, several non-profit organizations invest their time and effort in developing and revising electrical safety standards. Electrical safety codes and standards drafted by these organizations reduce the loss of life and ensure the safety of property, electricians, and equipment.

Listed below are some organizations that help address the numerous concerns related to electrical power.
