lectrical accidents happen daily; however, there are ways companies and individuals can reduce the occurrence of these accidents and protect everybody concerned from the physical, financial, and statutory consequences. The National Fire Protection Association (NFPA) regulation 70E provides a reference for facilities to meet the requirements of electrical workplace safety while regulation 70B outlines the best practices for setting up and maintaining and Electrical Preventive Maintenance (EPM) program. A crucial electrical safety element is ensuring that the equipment is safe before any work commences. NFPA 70E provides best practices for electrical safety and these recommendations are used by governmental enforcement agencies (such

Before conducting any maintenance task you must ensure that every precaution is taken to eliminate any risks to the maintenance engineers or operators - Personal Protective Equipment (PPE) should always be a last resort. IRISS IR Windows eliminate the risks associated with live inspections as they allow an IR Camera direct line of site access to live electrical components without opening an electrical enclosure. As such they provide an excellent means of accessing electrical equipment efficiently and safely as a second qualified person is not required to open and unbolt enclosures and the “triggers” of arc flash are not introduced as the panels remain closed. Therefore, the HRC level required when performing an IR or visual inspection through an IRISS IR window would be HRC 0.

address electrical maintenance or safe work practices. For the consensus standards on these topics we turn to NFPA 70B and NFPA 70E. Electrical power is the lifeblood of our everyday needs. Dependable electrical distribution is not an option – it is essential to corporate economic health; therefore, you need to ask the question; Is your

What would be the con- • Injury or death of personnel? sequences to your company if you lost • Negative impact to environment and electrical power?

As an asset, investment in an EPM needs careful planning and implementation. Information and guidelines contained within NFPA 70E and 70B can help you to get it right.
NFPA 70B NFPA 70B is a standard for implementing an effective Electrical Preventive Maintenance (EPM) program designed to reduce hazard to life and property resulting from the failure or malfunction of electrical systems and equipment. A welladministered EPM program reduces accidents, save lives, and minimize costly breakdowns and unplanned shutdowns of equipment. Without an EPM program, management assumes an increased risk of serious electrical failure and its consequences. 70B outlines the benefits of an EPM program: • Asset protection: Equipment lasts longer and performs better. • Risk management: Protect against accidents, lost production, and loss of profit. • Energy conservation: Maintained equipment operates more efficiently and utilizes less energy. • Uptime and profitability increased: Reduced interruption of production, better workmanship, and increased productivity. • Improved employee morale and reduced absenteeism • Insurance costs reduction: Due to the alternative high cost of inadequate maintenance. NFPA regards systematic and regular thermographic or infrared (IR) electrical inspections to be a critical component of an EPM program proclaiming these inspections have uncovered a multitude of potentially dangerous situations.

of these situations have prevented numerous losses. 70B is also specific about performing inspections while equipment is operating, stating IR surveys should be performed during periods of maximum possible loading but not less than 40 percent of rated load of the electrical equipment being inspected. In instances where IR windows are not available, equipment should be opened for inspection. When opening electrical panels to perform thermographic inspections per NFPA 70B guidelines and insurance requirements, they increase the risk of arc flash triggers. NFPA 70E rates the removal of bolted panels on energized electrical equipment to be in the highest hazard/risk category.
NFPA 70E Originally chartered in 1976 and released in 1979, the 70E Standard is intended for use by employers, employees, and OSHA to set standards for evaluating electrical safety in the workplace. Through eight revisions over 30 years, NFPA 70E Standard has made an indelible mark on safe work-practices globally. Basic compliance with the 2012 edition of NFPA 70E is actually established with a five-step process, which includes an arc flash analysis. The five steps are: Develop and audit on a regularly scheduled basis an electrical safe work practice policy. Conduct an electrical system study to determine the present degree of arc flash hazards and apply associated equipment labeling. Ensure adequate supplies of personal protective equipment (PPE) and proper tools for electrical workers. Conduct regularly scheduled safety training and audits for all electrical workers. Maintain all electrical distribution system equipment and components per manufacturers’ recommendations.
Hierarchy of Control (HRC) At the heart of NFPA 70E and OSHA initiatives is the hierarchy of control (HRC). This attempts to mitigate risk wherever possible. In order of preference, the HRC prioritizes: 1. Risk Elimination 2. Substitution (with lower risk) 3. Engineering Controls (such as arc resistant switchgear) 12
4. Safe Work Practices 5. PPE In short, the best way to reduce risk is to eliminate it. This is why NFPA 70E and OSHA state that electrical equipment should be de-energized prior to opening. Realizing this is not always possible for troubleshooting or in situations where shutting down is not viable or poses a risk, there is an allowance made for PPE to be used as a last resort – similar to the least preferred method in the hierarchy of control.
OSHA The Occupational Health and Safety Administration (OSHA) enforce electrical safety regulations in the United States. Although OSHA has not adopted and
does not mandate NFPA 70E compliance, you can be cited for non-compliance. If you wonder how this could be possible, remember that OSHA’s authority stems from the Occupational Safety and Health Act in particular Section 5(a)(1) and 29 CFR 1910.2(g). Section 5(a)(1) “General Duty Clause” states that employers “shall furnish to each of his employees employment and a place of employment which are free from recognized hazards that are causing or are likely to cause death or serious physical harm to his employees”. This is the clause most cited by OSHA where unsafe work conditions are found to exist. Section 29 CFR 1910.2(g) “National Consensus Standard” means any standard or modification which Continued on page 14
Use of an IRISS IR window maintains an IP65/NEMA 4X seal on the enclosure panel. Therefore, even when open, the window maintains what NFPA terms an “enclosed” and “guarded” condition. Additionally, scanning through an IRISS IR window is a noninvasive task that does not create a risk of electrical hazard (no change-ofstate). As long as the thermographer is confident that the equipment has been properly installed and maintained the equipment is not in danger of changing state.

has been adopted and promulgated by a nationally recognized standards-producing organization under procedures whereby it can be determined that persons interested and affected by the scope or provisions of the standard have reached substantial agreement on its adoption”. NFPA 70E is a national consensus standard and as such, non-compliance leaves employers open for citation under this clause if they are non-compliant.
It is safer to keep electrical equipment closed whenever possible. Non-invasive work processes, such as using and IRISS IR window, should be encouraged as a way to increase safety of personnel. In fact, use of IR windows has been estimate to reduce the risks of triggering an arc flash during an inspection to less than 0.1%.
