EXPECTATIONS What do you hope to escape from this class?

Slide 3

HURT AT WORK! “I’ve been doing it along these lines for a long time and ain’t been harmed yet.”

Slide 4

Introduction A normal of one laborer is shocked at work consistently Forth driving reason for death in the working environment today. More or less 1000 Electrocutions for every year. OSHA Citations Issued for 70% of all work environment electric shocks.

Slide 5

The Four Hazards of Electricity Shock Arc Has just turned into a perceived peril of power in the most recent 4 years. NFPA 70E was the first standard to perceive and step to minimize circular segment risks . Blaze Blast Burn Fire Ignition The frequency of flame ignition has dropped significantly since the appearance of the NEC and the establishment's acknowledgment prerequisites inside of the business. The NEC does not concern itself basically with the other three dangers of power.

Slide 6

Electrical Shock Received when current goes through the body. Seriousness of the stun relies on upon: Path of current through the body Amount of current moving through the body Length of time the body is in the circuit LOW VOLTAGE DOES NOT MEAN LOW HAZARD

Slide 7

Electrical Burns Entrance Wound: High resistance of skin changes electrical vitality into warmth, which delivers blazes around the passage point (dim spot in focus of wound). This man was fortunate; the current barely missed his spinal rope

Slide 8

Immediate Heart Muscle withdrawal Tingling Pain Breathing Disorientation Dizziness Long term Memory Loss Nervous issue Chemical uneven characters Damage to heart muscle Electric Shock

Slide 9

Electrical Burn Exit Wound: Current moves through the body from the passage point, until at last leaving where the body is nearest to the ground. This foot endured monstrous inward wounds which weren't promptly obvious, and must be removed a couple of days after the fact.

Slide 10

Electrical Shock Dangers of Electrical Shock Currents more prominent than 75 mA* can bring about ventricular fibrillation (fast, incapable pulse) Will bring about death in almost no time unless a defibrillator is utilized 75 mA is very little current – a little power drill utilizes 30 times as much Defibrillator being used * mA = milliampere = 1/1,000 of an ampere

Slide 11

Blast Electrical curve smolders at 37,000 degrees F. 4 times the sun's surface 2 times the focal point of an atomic blast Flash Ultra-violet light Temporary to perpetual visual impairment Arc Welding Sun blaze Arc – Two Dangers

Slide 12

Arc or Flash Burns This man was close to a force box when an electrical blast happened. In spite of the fact that he didn't touch the container, power arced through the air and entered his body. The current was attracted to his armpits on the grounds that sweat is extremely conductive.

Slide 13

Surface Burns Caused by passageway and way out of electrical streams through the body Can be created by a little measure of current first degree to third degree Tissue Burns Caused by current coursing through organs of the body Caused by ebbs and flows in abundance of 4 amps third degree Internal organs Typically lethal Burns – Two Types

Slide 14

BURNS Electrical Burns Most normal stun related, nonfatal harm Occurs when you touch electrical wiring or gear that is shamefully utilized or kept up Typically happens on the hands Very genuine damage that needs prompt consideration

Slide 15

Electrical Burn Internal Injuries This laborer was stunned by an apparatus he was holding. The passage wound and warm smolders from the overheated apparatus are clear.

Slide 16

Electrical Burn Same hand a couple of days after the fact, when huge subcutaneous tissue harm had brought about extreme (swelling for the most part tops 24-72 hours after electrical stun). To ease weight , which would have harmed nerves and veins, the skin on the arm was cut open.

Slide 17

Ranking Rank the accompanying 4 classes of electrical work by their risk potential. The most risky would be positioned 1, the minimum perilous 4. Transformer and Panelboards, Switchgear Overhead Power Lines J-boxes situated above 8’ J-boxes situated underneath 8’

Slide 18

University Of San Diego Study Overhead Power Lines 3% Panel sheets and Transformers 8% J-boxes situated above 8’ 68% J-boxes situated beneath 8’ 21% WHY?

Slide 19

NFPA - Background The first and essential mission of NFPA Primarily secured by establishment models contained in the National Electric Code and NFPA 70 The rate of flame ignition has dropped drastically since the approach of the NEC and NFPA and the acknowledgment of establishment necessities inside of the business.

Slide 20

NEC - Background The NEC is proposed for utilization essentially by the individuals who plan, introduce, and examine electrical establishments. Necessities for electrical wellbeing related work practices and upkeep of the electrical framework considered basic to security are not found in the NEC. The National Electric Code shields people from stun risks under typical conditions. It is not intended to shield us from irregular conditions We require extra approaches to shield from unusual conditions

Slide 21

NEW NEC REQUIREMENT New NEC Requirement The 2002 National Electrical Code has included Section 110.16, Flash Protection. Switchboards, Panel sheets, Industrial Control Panels, and Motor Control Centers that are liable to oblige examination, conformity, adjusting, or upkeep while invigorated should be checked to caution qualified persons of potential bend blaze risks. The checking might be situated to be plainly unmistakable to qualified persons before examination, change adjusting, or support of the hardware. Simply one more REMINDER TO WEAR YOUR PPE

Slide 22

What is NFPA – 70E? Published by the National Fire Protection Association, NFPA 70E was composed to ensure electrical laborers in each industry around a gadget equipped for producing a curve streak.

Slide 23

Who is Affected? Virtually any office lodging electrical gear falls under its rules. Inside of every association there are support laborers, circuit testers, machine administrators, or HVAC faculty that hazard an electric circular segment streak around such gear as meter banks, engine control focuses and transformers.

Slide 24

1. Characterize Energized Work Pretend you are the security supervisor for a vast electrical contractual worker. You must compose a meaning of “energized work” for your new arrangement manual. How might you characterize “energized work”. Select an individual from the gathering to introduce and guard your definition.

Slide 25

Energized Work Definition “any take a shot at electrical gear, circuits, gadgets, frameworks, or some other stimulated part(s) where a representative is obliged to intentionally, or could coincidentally, put any piece of his body or any kind of hardware into or around such electrical gadgets where the voltage has been regarded to be in abundance of 50 volts.”
