Electrical Safe Work Practices

1
ELECTRICAL SAFETY-RELATED WORK PRACTICES
2
Qualified Persons

• Those people that have training in avoiding
  electrical hazards while working on or near
  exposed energized parts.

3
Unqualified Persons

• Those people with little or no training in
  avoiding electrical hazards while working on or
  near exposed energized parts

4
Additional Training for Qualified Persons

• The skills and techniques necessary to
  distinguish exposed live parts from other parts
  of electrical equipment
• The skills and techniques necessary to determine
  the nominal voltage of exposed live parts
• The clearance distance specified in 1910.333(c)
  and the corresponding voltages to which the
  qualified person will be exposed

5
Approach Distances 1910.333(C)
6
Types of Training

• Section 1910.332 requires that instruction
  utilize either a classroom lecture or on-the-job
  training strategy. The degree of training
  provided is determined by the amount of risk to
  the employee

7
Safety Related Work Practices to which the
Standard Does Not Apply

• Generation, transmission and distribution
  installations
• Communications installations
• Installations in vehicles (i.e., ships,
  watercraft, railway, aircraft or automotive
  vehicles)
• Railway installations
• Less than 50 volts to ground
• If de-energized, all Lockout/Tagout procedures
  apply

8
Employer Responsibilities

• Safety related work practices to prevent
  electrical shock
• A written maintained copy of the procedures
  outlined in paragraph (b)(2) - Lockout and
  tagging written program
• Proper equipment for working around or near
  energized parts
• Portable ladders, non-conductive siderails

9
Employer Responsibilities(continued)

• Method to prevent any conductive materials or
  equipment from making contact with live
  electrical
• Method of making conductive apparel, such as
  jewelry, non-conductive
• Clothing such as wool, cotton or better
• Cleaning materials such as steel wool and
  conductive liquids from coming into contact with
  live electrical

10
Employer Responsibilities(continued)

• A visual inspection of all flexible cord sets
  (extension cords) and portable cord and plug
  connected equipment
• Proper illumination in confined or enclosed work
  spaces
• Providing appropriate insulated tools
• Tools must be tested annually

11
Personal Protective Equipment

• Hard Hat - Type B
• Rubber Gloves
• ASTM Label on Glove
• Testing and Maintaining Gloves
• If possible damage to rubber glove, then
  protective outer glove (leather glove)
• Note Leather gloves alone are not recommended.

12
Personal Protective Equipment

• Class Of Gloves
• (1) 10,000 Volts - Type 1
• (2) 20,000 Volts - Type 2
• (3) 30,000 Volts - Type 3
• (4) 40,000 Volts - Type 4
• (5) 1,000 Volts - Type 0
• (6) 500 Volts - Type 00
• (leather glove required over the top)

13
Personal Protective Equipment

• Face Shield or Safety Glasses
• Flying particles
• Face Shield - electric arcs, flashes resulting
  from electrical explosion.

14
Protective Tools Equipment

• 1. Insulated tools, handling equipment
• If equipment comes into contact
• with energized parts.
• 2. Protective shields, Barriers,
• Insulating materials.

15
Alerting Techniques

• Signs
• Symbols
• Tags
• Barricades
• Attendants

16
Preventing Shock

• Safety Planning before Starting the Work
• Determine location of work
• Determine voltage
• Determine Fire - Explosion Hazard

17
Preventing Shock

• Personal Qualification
• Have you received the necessary training to do
  the job?
• Do you feel good about the work assignment?
• Are you familiar with the equipment?

18
Preventing Shock

• Personal Qualification (continued)
• Do you understand exactly how to get the job done
  safely?
• Do you have all the necessary parts, tools and
  PPE?
• Have you studied the work to be done and thought
  it through?
• Can you deenergize?

19
Preventing Shock

• Never take the work of another employee.
• Is the lockout labeled correctly?
• Were the prints and drawing correct?
• Can I guard the electrical parts?
• Have I checked and tested my PPE?
• Is my PPE the correct type for the work?
