One of the most important steps in preventing electrical injuries is establishing an Electrically Safe Work Condition (ESWC) before work begins. While NFPA 70E clearly defines this process, its effectiveness depends on disciplined execution in the field.

An Electrically Safe Work Condition is achieved when all sources of electrical energy have been identified, the equipment has been properly disconnected, locked and tagged, stored energy has been addressed, the absence of voltage has been verified, and temporary grounds are applied when required. This begins with careful planning. Employees involved must understand the scope of work, identify all applicable energy sources, and follow established procedures to safely isolate equipment.

Lockout/tagout is a critical component of this process. All sources of electrical energy must be secured using approved lockout devices and tags. Once isolation is complete, the absence of voltage must be verified by a qualified person using properly rated and inspected test instruments. Meters should be tested on a known source both before and after use to confirm proper operation.

At Five Star Electric, our energy control procedure begins with a formal Method of Procedure (MOP) approval process, which includes a preliminary walkthrough with the foreperson to review the scope, energy sources, and hazard controls. Once the time and date for the operation are established, an Energy Control Checklist is completed during the energization or de-energization of electrical equipment. The checklist is submitted to both the General Superintendent and the Safety Department in real time and includes supporting photos that document each step of the process. This ensures all required procedures have been completed before work proceeds and keeps everyone informed as the operation is taking place. This approach supports accountability, improves communication, and promotes consistency across all our projects.

Establishing and maintaining an Electrically Safe Work Condition is not a one-time action. Any changes to the scope of work, equipment condition, or personnel involved require reassessment before work continues. When this process is applied with discipline and accountability, it reduces risk and prevents incidents. Most importantly, it ensures every worker returns home safely to their family and loved ones at the end of their shift.
