									Annual Refresher
   Electrical Safety
  Electrical Safety Precautions
Inspect equipment
  periodically.

  Make sure it is
  properly grounded.
  Replace any frayed or
  damaged wires and
  cords
   Electrical Safety Precautions, cont.
Keep all equipment far
  away from water
  If necessary, tape or
  secure the cord in place.
  Many outlets near sinks
  and other water sources
  are now GFI (ground fault
  interrupt). They will
  automatically shut off if
  there is a sudden power
  surge
  Electrical Safety Precautions, cont.

Remove all metal or
  conductive jewelry
  when working with
  electrical devices

  If they make contact
  with a live wire, you
  may be included in the
  circuit
  Electrical Safety Precautions, cont.
Don’t bury wires under
 carpeting or cover
 them with other
 objects

  Don’t cover vents on
  equipment, or place
  equipment too close to a
  wall or in cabinets that
  could block ventilation
  Electrical Safety Precautions, cont.
Use spark-free devices near
  flammable and combustible
  liquids
  Avoid conventional hot plates
  Refrigerators and freezers used
  to store chemicals should have
  external control switches, so
  that sparks are kept outside and
  away from fumes
  Electrical Safety Precautions, cont

Don’t overload electrical outlets or extension cords,
can cause fires.

  If a cord feels warm,
  disconnect it and don’t use it.
  Many operating instructions
  for large appliances warn
  against using an extension
  cord, which can overload.
Electrical Safety Precautions, cont
           Ever wonder why at gas stations the signs tell you to
           turn off cell phones while pumping gas?

           On May 14, 2004 at a Mobile Gas Station in New Paltz, New York,
           flames shot up around a 21-year-old college student whose cell
           phone rang while he was pumping gas. Firefighters said Matthew
           Erhorn received minor burns when the cell phone ignited vapors
           coming from the car's fuel tank as it was being filled.
           It doesn't take much of a charge to ignite gasoline vapors, New Paltz
           fire chief Patrick Koch explained. "Anything, really. Women's
           nylon stockings when they get out of a vehicle, that can cause a
           spark, too." It has been advised in the past to ground yourself
           before handling the gas pump.

           Electrical Equipments remain the number one cause of fires
           in offices and laboratories. If you see a frayed wiring do
           not attempt to fix it yourself but inform your supervisor or
           the facility coordinator to replace the wiring.
Electrical Fires
Use the “C” fire
extinguishers.

Never throw water
onto an electrical
water, hence never use
an “A” extinguisher
which is water-based.
  Electrical Safety Precautions, cont
Let only authorized or
  competent electricians
  repair electrical
  equipments

  If you don’t know how to fix
  something, don’t try it.
  Some devices store
  electricity, and you may get
  a shock
               Lockout/Tagout

29 CRF 1910.147 and 1910.333 apply to
  machines and equipment where there
  may be an unexpected startup or release
  of energy stored in various forms. These
  include fume hoods, hydraulic, x-ray
  machines, and other equipment
  connected directly to electrical lines and
  other energy sources.
               Lockout/Tagout

All switches, valves, or
other connections must
be either locked or
tagged in such a way that
they cannot be turned on
when being serviced or
repaired.
                      Lockout/Tagout
Only the authorized repair
  people can put on or
  remove the lock or tag.

If you turn on the electricity,
   you could cause serious
   injury, or death, to the
   person repairing the
   equipment
                    Lockout/Tagout
The laws do not apply to
  “bench top” devices and
  appliances, such as
  computers, refrigerators,
  or instruments, that are
  connected to an electrical
  outlet by a plug or cord.
  Once disconnected, these
  units no longer are a risk
    Electric Shock
First Protect Yourself
   Don't touch the person. That person might be
   energized, so take time to protect yourself
   Don't try to use a conductive tool to free the
   person
   Don't touch anyone who has become grounded.

Call 911 for help, IF the person:
   is obviously injured such as loss of consciousness,
   significant trauma, etc.
   has an altered mental status i.e.confusion, slow
   and/or slurred speech, etc.
   has other obvious injury i.s. laceration, burns, etc.
   or at the discretion of the shocked victim or
   supervisor
   In conclusion…
Electricity is used everywhere in
   the laboratory. Some are more
   common ones include
   balances, fume hoods,
   biological safety cabinets, light
   fixtures, telephones,
   centrifuges, refrigerators,
   heating mantles, autoclaves,
   computers, chromatographs....
  You can probably name more. With all this apparatus
  lying around, you must remember to respect electricity.
  All Done!
Make sure you fill out the quiz, sign it, and
 drop it off in my mailbox for record
 keeping.

Remember: This is an annual requirement.

         SEE YOU NEXT YEAR
