When working on or near electricity or electrical equipment you must be trained in & use Electrical Safety Related Work Practices NFPA 70E 2004

These Standards apply to both Qualified Workers & Unqualified Workers

Electrical Safety Statistics Average of 4,000 non-disabling and 3,600 disabling electrical contact injuries annually in the United States Average of 4,000 non-disabling and 3,600 disabling electrical contact injuries annually in the United States One person is electrocuted in the workplace every day. One person is electrocuted in the workplace every day. Electrocutions were the fourth leading cause of traumatic occupational fatalities. Electrocutions were the fourth leading cause of traumatic occupational fatalities employees are sent to the hospital every day with electrical burns employees are sent to the hospital every day with electrical burns. Over 4 workers every day go to the burn unit due to arc flash. Over 4 workers every day go to the burn unit due to arc flash.

Electrical Safety Related Work Practices 29 CFR C.331 Scope C.332 Training C.333 LOTO - MAD’s - Safe work practices C.334 Use of equipment - Portable - Fixed - Test C.335 PPE & warning Based in part on NFPA 70 E Electrical Safety Related Work Practices.

TRAINING REQUIREMENTS  NFPA 70E Covers you in General Industry & Construction  29 CFR (b)(1): Employees shall be trained in and familiar with the safety related work practices required by through that pertain to their respective job assignments.  29 CFR (b)(2): The employer shall instruct each employee in the recognition and avoidance of unsafe conditions and regulations applicable to his work environment to control or eliminate any hazards or other exposures to illness or injury.

What electrical hazard is responsible for nearly 80% of the accidents, incidents and fatalities among Unqualified Workers? Electrocution Usually associated with a lack of equipment grounding!

Scenario: You’re the foreman doing your walk around / inspection and you come upon a worker using a __________. Floor buffing machine Vacuum cleaner Portable electric tool You fill in the blank What do we always find wrong? Electrocution Hazard!

(e)(1) Cords & Cables (a)(2)(i) Portable Electric Equipment Worn or frayed electric cords or cables shall not be used.  Don’t abuse, damage, or use for a rope.  Visually inspect before use.  D eformed / bent pins or blades, missing pins or blades, GROUND pin.

Safety Professionals need to follow safe electrical work practices too ! I had been using this all day and had no previous problems. The checker was plugged into a 4 outlet metal cased, metal covered plug assembly. There was almost an instant flash caused by what I guess was internal arcing – this flash blinded two other personnel and myself. You could hear the arcing for several seconds and then it died away. I could smell something burning and wondered if it was me!

UNQUALIFIED WORKERS Are normally protected by the installation requirements by Subpart K or S (covers on no exposed live parts). However If their work exposes them to electrical hazards which would otherwise be protected -- they must be trained. Trained to recognize and avoid hazards encountered or likely to encounter while working.

Unqualified workers can’t be trained to recognize and avoid electrical hazards. Because it is common sense.

Qualified Workers Are normally protected by the installation requirements by Subpart K or Subpart S. However When their work exposes them to electrical hazards which would otherwise be protected according to Subpart K - they must protect themselves against ALL the electrical hazards. Shocks - Electrocution - Arc Blast - Burns -Explosion

80 % of the electrically related accidents, incidents, and fatalities among Qualified Workers Caused by Arc Blast / Arc Flash

Qualified Workers Shocks - Electrocution - Arc Blast - Burns -Explosion Deenergize – LOTO Use Personal Protective Equipment Unless employer can demonstrate infeasibility or greater hazard.

LOCKOUT AND TAGGING (B)(2) De-energized – release stored energy De-energized – release stored energy Apply locks and tags Apply locks and tags Verify de-energized condition Verify de-energized condition

PERSONAL PROTECTIVE EQUIPMENT (PPE) 29 CFR (a)(1)(i): Employees working in areas where there are potential electrical hazards should be provided with, and should use, electrical protective equipment that is appropriate for the specific parts of the body to be protected and for the work to be performed. 29 CFR (a)(1)(i): Employees working in areas where there are potential electrical hazards should be provided with, and should use, electrical protective equipment that is appropriate for the specific parts of the body to be protected and for the work to be performed.

TOOLS AND EQUIPMENT 29 CFR (a)(2)(i) When working near exposed energized conductors or circuit parts, each employee shall use insulated tools or handling equipment might make contact with such conductors or parts. When working near exposed energized conductors or circuit parts, each employee shall use insulated tools or handling equipment might make contact with such conductors or parts.

Basic Rules of PPE Never work on tasks with exposures greater than 40 cal/cm 2 Never work on tasks with exposures greater than 40 cal/cm 2 Layering is required to lower thermal exposure to the body Layering is required to lower thermal exposure to the body No flammable or meltable clothing No flammable or meltable clothing Maximum coverage Maximum coverage Fit and comfortable Fit and comfortable Maintenance of equipment Maintenance of equipment
