Electrical Hazard Classification

Electrical hazard classification is an important requirement of an employer’s Electrical Safety Program.? The employer defines worker roles that are authorized to complete energized electrical work tasks and shall complete electric shock and arc flash hazard identification.? Ensuring the employer has a clear understanding of the latest electrical hazard classification information is extremely important.

The USA DOE has developed and implemented an Electrical Safety Program.? In reviewing the electrical hazards related to their business/projects and work tasks performed they created a comprehensive electrical hazard classification system and then applied this against work tasks and developed and implemented a comprehensive qualitative risk assessment process that included a related risk matrix.?

In Table 1 below TW Becker Electrical Safety Consulting Inc. has provided a simple summary of the electrical hazard classifications the USA DOE initially created and evolved over the years.? Some of the information is also extracted/validated from other information sources as noted in the references below the table.

PRODUCT SPOTLIGHT

Not all arc rated gloves are created equal. The gloves' packaging may state "Arc Rated" ... but does this mean they meet the latest Standard: ASTM F2675 Standard Test Method for Determining Arc Ratings of Hand Protective Products Developed and Used for Electrical Arc Flash Protection.

Risk Control: Knowledge is Power

Energized work work can be completed when the incident energy is greater than 40.0 cal/cm2. Pressure from an arcing fault does not correlate to incident energy.
