Electrical - Lesson 2

Bureau of Labor Statistics (BLS)

According to them, 289 employees were killed by contact with electric current in 2002

Extra-duty outlet box hoods

Another requirement for 2011 NEC

Electricity

Can cause serious injury or death and loss of properties if you fail to recognize electrical safety practices

Select the right tool

Choose tools with soft grips that fit your hand comfortably. A good handle grip prevents your hand from slipping while using the tool. Consider using tools that reduce the amount of force or movements to use.

- Iron - Hair dryers - Ungrounded polarized and non-polarixed cord caps

Commonly used in the area of GFCI protected areas and present the same shock hazard found in other areas

Outlets that supply BOAT HOISTS, not just RECEPTACLE OUTLET

GFCI protection is required for?

- Six feet of laundry sinks - Wet bar sinks - Utility sinks

GFCI protection should be installed where?

289 emplooyes

How many employees was killed in 2002 due to contact with electric current

Electricity

Improves life

2008 National Electrical Code

Introduced the concept of tamper-resistant receptacles on dwelling units

Revising

Made to emphasize that all 15A and 20A, 125V receptacles within 6 feet of the dwelling unit, laundry, or utility sink have GFCI

- 15 or 20A, 125V receptacles to include RECEPTACLES LOCATED OUTDOORS THAT ARE ACCESSIBLE TO THE PUBLIC - for heating, air-conditioning, and refrigeration equipment

New requirements expands on:

Practice good housekeeping

Pick up debris and scrap material to prevent trips, slips, and falls. Good housekeeping allows you and your equipment to work efficiently.

Lighten your load

Plan what you are going to do. Carry only the tools or equipment you will need. Wear a tool belt that fits well and distribute the tools and materials evenly.

Outlet box hood

Plate that is made from either one metal or plastic that covers the receptacle or convenience outlet

Cardio pulmonary resuscitation (CPR)

Should be administered if the heart has stopped beating in addition to loss of breathing.

Occupational Health Safety Act (OHSA)

States that some unsafe electrical equipment and installations can be identified by faulty insulation, etc.

Article 210.63 of NEC series of 2005 page 54

The GFCI protection requirement for commercial kitchens was clarified by adding a definition of a kitchen

Disconnect him

The immediate action when somebody is experiencing electrical shock

U.S Occupational Safety and Health Admission

They are the ones that cited three prossible factors causing electrical accidents

1) Work involving unsafe equipment and installations (unsafe condition) 2) Workplaces made unsafe by environment (unsafe condition) 3) Unsafe work performances

Three possible factors causing electrical accidents

Ground Fault Current Interrupter (GFCI)

To protect people from the deadly effects of electric shock that could happen if parts of an electrical aplliance or tool become energized due to ground fault

Tamper-resistant receptacles

Tough, damage resillient, and heavy duty receptacles

Arch Fault Circuit Interrupter (AFCI)

Type of duplex receptacle or circuit breaker that automatically breaks off the circuit when it detects dangerous electrical arcing faults that could initiate ELECTRICAL FIRES

Protect yourself

Wear safety gear that fits well. Protect your knees from hard, sharp surfaces by wearing knee pads. Wear appropriate eye protection to protect your eyes from debris and flying particles. Protect your hands from friction and sharp edges by wearing gloves.

Arch Fault Circuit Interrupter (AFCI)

What did NEC considered using in 2011

15A and 20A receptacles installed in wet locations

What must be enclosure that is weather-proof when an attachment plug is inserted?

15A, 201, 125V, and 250V receptacles

What should be weather-resistant

2011

When did the NEC required that all receptacles should be replaced with tamper-resistant receptacles

Countertop surfaces within 6 feet of wet bar sinks

Where was the GFCI requirement only previously applied?

Change body positions

Working overhead, at floor level, or in cramped spaces forces the body into awkward postures. To relieve muscle tension and improve circulation, change body positions, do alternate tasks, and stretch your muscle throughout the day.
