April 23, 20212IntroductionA management systems and operational audit was performed at ABC Company Maintenance Department witha focus on electrical safety. This was the first electrical safety audit performed at the department after anupdated Electrical Safety Program (ESP) was rolled out in and electrical safety training offered to certainemployees. Personal protective equipment for shock and arc flash was also recently implemented. The auditwas based on the requirements of the NFPA 70E 2018 Standard for Electrical Safety in the Workplace as thiswas last revision used for the ESP.The audit was performed by Zarheer Jooma and attended by Employee #1 and Employee #2. All systems,procedures, and operational activities that have been well established and documented by the maintenancedepartment were audited in detailed. Each requirement was first verified to exist in a management system,then the workers or the leadership (as appropriate) were interviewed to demonstrate understanding of therule and provide documented (or observable) compliance. A brief discussion regarding contractors andprojects was held with Employee #3.Noncompliant observations may consist of two types, those where no evidence was found or werenoncompliance was clearly observed. The report attempts to differentiate between these two types ofobservations. The recipients of this report are encouraged to identify omissions and provide documentedevidence to remediate noncompliant findings.Not all compliant observations are listed in this report, instead, only a select few that are known high risk itemsare presented.Certain sections of the audit were not covered since the maintenance department is in the process of rollingout newly required work practices as per the ESP. As such, some audit questions were answered verbally asdocumentation is still being developed. Examples are the Energized Electrical Work Permit (EEWP) andsupervisory work inspection for working inside the restricted approach boundary. This part of the audit wasdiscussed with the team to create awareness of what future audits will be examining.The maintenance department appears to be working under adequate policies and procedures, however, sometime is still required for the electrical safety principles to become part of the work culture. The observationspresented below appear more to be learning and practice challenges than deep rooted systemic deficiencies.The results of the audit are presented in the next section and detail the appropriate article of the NFPA 70E 2018, the observation, and recommendations where applicable.The audit results are presented in three sections: (i) Energy Control, (ii) Visual Observations, and (iii) GeneralCompliance. The conclusion and recommendations on general items then follows in the final section.(502) 716-7073 Office(502) 371-6300 Fax3018 Eastpoint ParkwayLouisville, KY 40223www.e-hazard.cominfo@e-hazard.com

In such cases OSHA and NFPA 70Erequires training on home laundering in line with the manufacturers care instructions. It isrecommended that a brief training program based on the manufacturers label be establishedand implemented through NetLearning.(i) Gloves procured are compliant with ASTM D120(ii) Test dates are within specification(iii) No glove program exists – recommend that a documented program be implemented(iv) During demonstration on the use of the glove, employees donned the glove without apre-inspection(v) No glove storage bag provided to employees(vi) Employees are provided with Class 0 gloves that are rated for a maximum 1000V AC. Aclass 00 glove rated for a maximum 500V AC will be more comfortable for workers.(vii) It is recommended that a two color glove program be implemented for ease ofidentification of six monthly electrical glove test compliance.(i) During the observation, the employee did not inspect the leather over protector before theglove was donned.Not used(i) Employees appeared to use arc rated clothing adequately: buttoned up, sleeved rolleddown, shirt tucked in.(ii) Employee observed using polyester cotton blend T-Shirts that are not allowed by OSHAand NFPA 70E.(iii) Metal belt buckles should not be used inside the arc flash and shock boundaries –employees indicated that belts are being used inside these boundaries.(i) Face shields are still being rolled out and a sample was inspected and found compliant toexisting standards.(ii) Employees appeared unclear on when to use face shield – arc flash study should beupdated.(iii) Presently face shields are being shared until such time that individual face shields can beprovided. This is not recommended and must be resolved as soon as possible.(i) Balaclava – compliantTest Instruments and Equipment;Voltmeters are Cat III(i) Voltmeters inspected were compliant.(ii) There is unofficial calibration program for meters. It is recommended that the program beextended and formalized to include all meters and include an electrical insulation test as well.Test leads and instrument checkedvisually before useEmployees wear arc rated clothingthat completely covers allflammable clothingEmployees wear non-conductiveClass E hard hatsEmployees wear face shields asrequiredTest leads were not inspected by employee during the visual observation.(502) 716-7073 Office(502) 371-6300 Fax(i) Balaclava – compliantHard hats are Class ENot observed3018 Eastpoint ParkwayLouisville, KY 40223www.e-hazard.cominfo@e-hazard.com

The employees raised uncertainty regardingthe fire resistance of such barricades. Since barricades are used at the arc flash boundary,this isn’t seen as too much of a risk.

An updated study is an immediatepriority.(ii) Many panels not provided with Arc Flash and Shock Labels(iii) A sticker type label was coming loose – recommend that only engraved labels be used toidentify equipment(iv) Panels dual-labeled (contradictory) and handwritten labels observed – both incorrect andnot allowed(v) Incorrect voltages indicated on multiple panels. This is a serious finding and must beremediated urgently.(vi) Arc flash study labels attached on certain equipment is incorrect indicated 0cal/cm2incident energy when the actual energy is much higher. This is a serious finding.(vii) ELRB Panel door was left opened.

April 23, 202113ConclusionThe audit was performed with the understanding that ABC COMPANY has just recently adopted certainelectrical safety work practices. As these safe work practices are implemented by the employees, moredetailed audits should follow. There are several methods that can be used to resolve the noncompliantobservations presented in this report. It is recommended that ABC COMPANY discusses possible solutions andprioritizes the order in which these solutions are implemented.An updated audit should be performed once the NFPA 70E – 2018 Standard is implemented at ABC COMPANY.In the interim, it is recommended that this audit be performed at other departments, including the LaundryDepartment – preferably within the next six months.The following are general recommendation and are considered critical requirements:1. Undertake arc flash engineering study and provide labels. This is an OSHA requirement based on1910.132(d) that requires the employer to identify the electrical hazard and provide PPE. This sectionfurther requires that the workplace hazard (arc flash) be documented and certified [1910.132(d)(2)].2. Provide written guideline covering the:a. Glove Programb. Electrical drawings and arc flash engineering study updates when projects with electrical partsare planned, executed, and completedc. Demonstration of skills to determine Qualified Electrical Worker3. Ground Grid assessment and testA follow up audit should be performed in 2019 at the Maintenance Department at ABC COMPANY.Audit report compiled by:Zarheer JoomaElectrical Engineer Pr. Eng.
