  1. This is session 1B NFPA 70E – Electrical Safety in the Workplace. Welcome to DIOSH Day 2013

  2. Chad E. WhiteheadGDS Associates, Inc. , an Partner from Ameren Illinoisand Paul FlynnTrainingDirector, NECA/IBEW JATC, Local 34

  3. This session is an explanation of the NFPA 70E and its relationshipto OSHA as well as a demonstration of PPE. You will see three tofive scenarios of how to apply the 70E. The session will close with a“dressing out” to show full level of PPE

  4. NFPA 70E table handouts. Examples of PPE and tools. Starting point for a benchmarking discussion. The “Short” –no pun intended. References. Key take aways for the day

  5. OSHA says … NFPA 70E says ….. BOB says ….. Or You tell someone that OSHA says… How do we normally describe safety?

  6. What does OSHA say? SEC. 5. Duties (a) Each employer -- (1) 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; (2) shall comply with occupational safety and health standards promulgated under this Act. (b) Each employee shall comply with occupational safety and health standards and all rules, regulations, and orders issued pursuant to this Act which are applicable to his own actions and conduct. http://www.osha.gov/pls/oshaweb/owadisp.show_document?p_table=OSHACT&p_id=3359

  7. Food processing plant Holiday weekend/overtime scenario Automatic transfer switch -15,000 volts No PPE Video, Is this environment free of recognizable hazards?

  8. Notice PPE. Is there a boundary? Do they do anything wrong? Video is this environment free of recognizable hazards

  9. How does an employer provide an environment? For this mornings discussion- We have an environment that contains electrical hazards. Electrical Safety in the Workplace. environment

  10. We want to relate OSHA to NFPA 70E. OSHA states this… NFPA 70E states this… Federal Register / Vol. 55, No. 151/Monday, August 6,1990/ Rules and Regulations. Final Rule. Forward of the 2012 NFPA 70E. Relationship

  11. 29 CFR 1910.301-399 for General Industry. Also known as Subpart S. Covers utilization or electricity users. 29 CFR 1910.269 for General Industry. Covers generation, transmission, and distribution or electric suppliers. Electrical safety in the workplace is in 1910.331-335. What part of OSHA?

  12. This subpart addresses electrical safety requirements that are necessary for the practical safeguarding of employees in their workplaces and is divided into four major divisions as follows: 1910.301(a) Design safety standards for electrical systems. These regulations are contained in 1910.302 through 1910.330. Sections 1910.302 through 1910.308 contain design safety standards for electric utilization systems. Included in this category are all electric equipment and installations used to provide electric power and light for employee workplaces. Sections 1910.309 through 1910.330 are reserved for possible future design safety standards for other electrical systems. 1910.301(b) Safety-related work practices. These regulations will be contained in 1910.331 through 1910.360. 1910.301(c) Safety-related maintenance requirements. These regulations will be contained in 1910.361 through 1910.380. 1910.301(d) Safety requirements for special equipment. These regulations will be contained in 1910.381 through 1910.398. 1910.301(e) Definitions. Definitions applicable to each division are contained in 1910.399. [46 FR 4056, Jan. 16, 1982; 46 FR 40185, Aug. 7, 1981] http://www.osha.gov/pls/oshaweb/owadisp.show_document?p_table=STANDARDS&p_id=9878 1910.301-330

  13. 1910.331 and NFPA 70E 90.2 include employee work areas covered and not covered by these standards. 1910.331 provides the OSHA definition for a qualified and unqualified worker. NFPA 70E 90 also provides the organization of the standard and definitions in article 100. Scope

  14. OSHA qualified person -One who has received training in and has demonstrated skills and knowledge in the construction and operation of electric equipment in installations and the hazards involved. NFPA 70E qualified person -One who has skills and knowledge related to the construction and operation of the electrical equipment and installations and has a receipt safety training to recognize and avoid the hazards involved. Definition of Qualified vs. Unqualified

  15. 1910.332 and NFPA 70E 110.2 (every three years) The long and the short of it. Training doesn’t always make you qualified. You can be qualified on for some tasks and not others. The employer ultimately decides who is and who is not qualified. Training

  16. 1910.332(b)(3)(i) The skills and techniques necessary to distinguish exposed live parts from other parts of electric equipment. 1910.332(b)(3)(ii) The skills and techniques necessary to determine the nominal voltage of exposed live parts, and 1910.332(b)(3)(iii) The clearance distances specified in 1910.333(c) and the corresponding voltages to which the qualified person will be exposed. Note 1: For the purposes of 1910.331 through 1910.335, a person must have the training required by paragraph (b)(3) of this section in order to be considered a qualified person. Note 2: Qualified persons whose work on energized equipment involves either direct contact or contact by means of tools or materials must also have the training needed to meet 1910.333(C)(2). http://www.osha.gov/pls/oshaweb/owadisp.show_document?p_table=STANDARDS&p_id=9909 OSHA’s Long Text:

  17. NFPA’s Long Text:NFPA 70E 110.2 (D)(b)(1-4)paraphrased- • 1-Distinguish exposed live parts from other parts. • 2-Determine the nominal voltage of exposed live parts. • 3-The clearance distances specified in Table 130.4(C)(a) and (b)and the corresponding voltages to which the qualified person will be exposed. • 4-The decision-making process necessary to determine the degree and extent of the hazard and the personal protective equipment and job planning necessary to perform the task safely. 2012 NFPA 70-E pp-15

  18. Is it Hot or not? • What’s the voltage? • What are my boundaries? • What do I need in order to do this safely? • Training • PPE • Tools The Short-again no pun intended

  19. Work on or near exposed energized parts Selection and use of safe work practices. NFPA 70E 120 and 1910.147 or LOTO Shock hazard analysis Arc Flash analysis 1910.333 and nfpa 70e -130

  20. General requirements Portable equipment Conductive work locations Test equipment- meters 1910.334 and nfpa 70e -110

  23. Hazard Risk Categories Category 0 – Up to 1.2 cal/cm2 Category 1 – 1.2 to 4 cal/cm2 Category 2 – 4.1 to 8 cal/cm2 Category 3 – 8.1 to 25 cal/cm2 Category 4 – 25.1 to 40 cal/cm2 Over 40 cal/cm2 – Unacceptable Risk
