Why NRTL Approval Matters: Protecting Workers
Recent statistics reveal that workplaces utilizing NRTL-certified products experience a 30% decrease in electrical-related accidents. This highlights the crucial role of NRTL certification in ensuring worker safety and reducing the risk of electrical hazards.
A recent news report announced that the Occupational Safety and Health Administration (OSHA) is intensifying its focus on enforcing NRTL certification requirements to enhance workplace safety standards. This development underscores the growing importance of NRTL certification in mitigating workplace risks and protecting employees.
We’re talking about parts of electrical systems like electrical power outlets and dead-front electrical switchboards. Electric-powered industrial trucks must also meet certain testing requirements to be listed and labeled.
Not only does it make sense to have listed and labeled for safety reasons, but OSHA also requires it in their electrical safety standards.
What does “listed” mean?
Listed and labeled electrical products have the mark of a nationally recognized testing laboratory (NRTL), indicating the products were tested under standards designed to ensure protection from electrical hazards. Using electrical products that are not listed and labeled can pose serious hazards to employees, such as electrocution, burns, and arc flash and blast, so it’s important to make sure your electrical products and equipment are listed and labeled.
Equipment is “listed” if it’s included in a list that:
- Is published by an NRTL that makes periodic inspections of the production of such equipment, and
- States the equipment meets nationally recognized standards or has been tested and found safe for use in a specified manner.
There are many NRTLs, but one of the most common NRTLs for electrical products is Underwriters Laboratories Inc. They test numerous types of equipment, including electrical products, to 82 different standards. Examples include UL 231 for electrical power outlets and UL 891 for dead-front electrical switchboards.
As mentioned earlier, manufacturers of electric-powered industrial trucks must meet UL 583 for their product to be listed as safe to use.
What does “labeled” mean?
Being “labeled,” means the equipment has attached to it a label, symbol, or other identifying mark of a NRTL:
- That makes periodic inspections of the production of such equipment, and
- Whose labeling indicates compliance with nationally recognized standards or tests to determine the equipment is safe when used in a specified manner.
With electric-powered industrial trucks, the UL rating will be stamped on the forklift’s data plate or tag. This means the equipment has been inspected by UL and they’ve determined it’s designed to not cause a fire in the workplace.
Keys to remember
Ensure all the electrical products, components, and equipment you use are listed and labeled. This means they have the mark of a nationally recognized testing laboratory.
