Arc flash labeling is one of the measures towards protection in the working places that use electrical equipment. These labels should contain important data—to minimize risks and prevent workers from severe burn injuries in case of arc flashes.
It is crucial for practices conforming with the necessities and regulations of arc flash labels to be effectively understood. Herein we address some of the most common questions concerning arc flash labels, to assist you and your organization as per the set safety regulations.
What is Arc Flash Labeling?
Arc flash labeling is the process of applying warning labels on electrical equipment to notify the personnel of possible arc flash risks. These labels are important to convey the potential of an arc flash, which is a discharge of electric current through the air between two conductors and accompanied by a luminous glow, heat, and energy. This enables the workers to easily locate regions with risks of getting injured hence minimizing the risks involved.
What are the Impacts of Arc Flash Labeling?
Arc flash labeling is beneficial since it aids in increasing the safety of employees in organizations. High voltage electrical systems are particularly dangerous and present significant threats. The electric arc’s flashes can lead to burn injuries and in extreme cases, fatalities are bound to occur if the workers do not have any clue of the risks involved. Labeling, if correctly done, will abide by OSHA and NFPA guidelines so as to discourage organizations from facing fines as well as, most importantly, save the lives of the employees.
What Components Should the Arc Flash Label Include?
According to the NFPA 70E standard, an arc flash label must contain specific information, including:
a. The nominal system voltage;
b. The distance that arc flash covers;
c. Personal Protective Equipment (PPE) needed;
d. Incident energy or arc flash category.
They enable the workers to note the level of danger that is posed by the specific equipment and take precautions.
When Should Arc Flash Labels Be Updated?
Arc flash labels should be changed every now and then, especially when there are additions, improvements or repair of the electrical system. It is also advised that the labels should be occasionally updated, and this is often done after a period of five years. Failure to update the labels creates a problem of either presenting wrong information or information that is out-dated, hence becoming dangerous to the safety of workers.
Who is Responsible for Arc Flash Labeling?
Employers or facility managers are usually in charge of arc flash labeling or documenting the necessary information. They have to guarantee that any electrical equipment is clearly labeled and must meet the required safety standards. Employers need to engage qualified electrical contractors or consultants to conduct arc flash studies which identify the right labeling for the facility.
Conclusion
Arc flash labeling is critical for ensuring that a workplace is as safe as possible by providing personnel with the information they need about electrical risks. Through being conversant with the labeling requirements, changing the labels as may be required, and adhering to the safety measures, businesses may greatly reduce the incidences of arc flash occurrences.
