 Electrical Safety
Job Task Analysis

September 9-10, 2009
ELECTRICAL SAFETY JOB TASK ANALYSIS REPORT

I. Introduction:

       On September 9-10, Multi-Skill Training Services, Inc. (MST) visited the ABC New York facility
   to conduct an Electrical Safety Job Task Analysis for the SMAG Wireman department. The purpose of
   the analysis was to identify the appropriate electrical safety training that is required to allow employees
   from your department to work safely with electrical machinery and components. The final results
   obtained from this analysis will form the basis and framework for the design and development of an
   electrical safety training program that is focused on the specific needs of your facility.

II. Methodology:

      The analysis began initially when we were presented multiple JHA’s and SOS’s identifying your
   department’s job duties and task. Once that information was documented and potential electrical
   hazards were identified, an electrical hazards survey was developed. The foundation of this survey was
   provided by the 2009 Edition of the NFPA 70E Standard for Electrical Safety in the Workplace.
   Specifically used were Table 130.7(C)(9)(a), Hazard/Risk Category Classifications, and Article 340,
   Safety-Related Work Practices: Power Electronic Equipment.

      The process began with a meeting with an EOHS coordinator who provided us with the
   organizational and facility structure of the New York campus. He then coordinated department tours
   and participant interviews.

       We initially began our interview process in your department surveying two (2) team members: Ed
   Boehm and Dan Schroer. Secondly, we performed a brief walkthrough observing the different tasks
   that exposed the employees to potential electrical related hazards. The participants were asked to fill out
   a written survey identifying their day-to-day job duties and task relating to possible electrical
   exposures.

       In addition, we talked with various employees concerning relevant JHA’s and SOS documents
   relating to their scope of work. While on site, during our walkthrough, we researched the information
   stated in the document for possible errors and omissions. After our interviews and observations we
   captured various forms of information and brought them back to MST for further interrogations using
   multiple codebooks and standards. The audited JHA’s and SOS’s are attached for further clarifications
   and updates that will be performed by Cadick Corp.

III. Results:

   The data gathered from the interview phase, along with our on-site observations, have been organized
   identifying the potential electrical hazards with which employees come in contact within their
   department. We have also attached the training outline associated with those findings.

   *Notes:

    The Training Needs Outline and the Job Task Analysis Summary charts were derived from the
   information in NFPA 70E 2009 edition. However, these documents could be affected by the final
   outcome of the Flash Hazard Analysis.

   Any prescribed training shown above for RF or Laser Safety training is delivered by other
   vendors.


IV. Observations and Comments:

      During the interviews, we discussed the following skills needed to work safely on electrical
   equipment (as identified by NFPA 70E):
    Knowledgeable in the construction and operation of equipment or specific work methods
    Trained to recognize and avoid electrical hazards
    Capable of making safe voltage measurements

      Insulated hand tools as per NFPA 70E, Part II, Sections 3-4.1.1 were not being used by employees.
   When used properly and within their voltage range, insulated hand tools can be utilized to provide
   additional safety from electrical shock and arc burns. Voltage rated gloves should also be worn by
   everyone exposed to energized conductors above 50 volts. In addition, correctly categorized meters
   should also be used appropriately.

V. Commendations:
       During the analysis, MST observed the following, for which we would like to commend ABC:
          The willingness of each survey participant
          A team-oriented environment
          A cooperative and helpful attitude between departments

VI. Recommendations:

   1) Documentation of electrical hazards using results of arc study
               Place appropriate labels on all relevant equipment
   2) Implement electrical safety training
   3) Purchase the appropriate insulated tools and PPE items per department
   4) Purchase appropriately categorized meters
   5) Develop and/or continue to update specific lockout/tagout procedures
   6) ABC should enforce a consistent electrical safety program. Those that continue to violate this
      policy should be reprimanded for the safety of themselves and others.

VII. Conclusion:
      All of the employees, including management, are anticipating a customized electrical safety-training
   program that is relevant to their job. Although invisible, electricity is always present around identified
   hazards. The electrical safety training will help employees to feel more secure on the job and allow
   ABC to become a safer and more efficient workplace.

       MST wishes to thank the management and hourly personnel at your facility for their excellent
   cooperation in assisting us in this analysis. The Electrical Job Task Analysis we conducted has
   identified and validated the safety training required of each employee. Using this information, a
   customized electrical safety-training program is now being developed and will soon be implemented.

                                            Thank you,


                                            ___________________________________
