Presentation on theme: "ELECTRICAL SAFETY-RELATED WORK PRACTICES Qualified Persons Those people that have training in avoiding electrical hazards while working on or near exposed."— Presentation transcript:
Qualified Persons Those people that have training in avoiding electrical hazards while working on or near exposed energized parts.
Unqualified Persons Those people with little or no training in avoiding electrical hazards while working on or near exposed energized parts
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
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
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
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
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
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
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.
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)
Personal Protective Equipment Face Shield or Safety Glasses Flying particles Face Shield - electric arcs, flashes resulting from electrical explosion.
Protective Tools & Equipment 1. Insulated tools, handling equipment If equipment comes into contact with energized parts. 2. Protective shields, Barriers, Insulating materials.
Preventing Shock Safety Planning before Starting the Work –Determine location of work –Determine voltage –Determine Fire - Explosion Hazard
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?
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?
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?
