Title: Safety

  • Engineering Lab Safety

By Christie Schmitt
Essential Questions
  • Why is lab safety important in your engineering

Occupational Statistics
  • Occupational Safety is the most important task or
    job skill workers can master!
  • The Statistics
  • On average 15 workers die in the US each day from
    work related injuries.
  • Nearly 3,450 are injured (most of which have a
    year or less on the job)
  • Leading causes of injuries are overexertion,
    contact with objects or equipment, and falls.

Work Related Injuries
Sprains, strains, tears 525,390 41.7
Bruises 114,680 9.1
Cuts, punctures 114,140 9
Fractures 94,040 7.4
Heat Burns 18,510 1.4
Carpal Tunnel Syndrome 18,710 1.4
Basic Safety
  • Know the location of all fire extinguishers. Know
    which extinguisher contains the right
    fire-fighting agent for each type of fire
  • Class A wood paper products
  • Class B flammable liquids
  • Class C electrical equipment
  • Always wear eye protection. Even if youre not
    doing anything, other people are and a flying
    piece of wood or metal from their job can easily
    injure you.

    care. Carry pointed tools with the points down.
    Carry all tools so they dont pose a danger to
    the people around you.
  • Report any equipment that doesnt seem to work

Basic Safety

    points and heavy end down.
  • Cut away from yourself when you use chisels and
    other edged tools.
  • Dont force screws make sure that the correct
    screw for the job is being used.

Safety Rules for Power Tools
  • Dont operate a machine until receiving proper
    instruction, fully understanding how to use it,
    you have permission.
  • Wear eye protection
  • Use all safety guards exactly as they are
    supposed to be used.

    when not in use.
  • Always cut wire leads so the clipped wire falls
    on the table top and not toward others.
  • Do not touch the tip end of a soldering iron to
    check for heat.
  • Avoid an earth ground when working with AC
    powered units.
  • Only work with powered units when necessary for
  • Avoid skin contact with chemicals.

Safety Rules for Electronics
  • Replace all screws, not just some.
  • Use the correct cleaning solvents for the job.
  • Avoid pinching wires when putting equipment back
  • Use a heat sink when soldering temperature-sensiti
    ve components.
  • Never solder a circuit that has the power
  • Double check circuits for proper connections and
    polarity prior to applying the power.
  • Observe polarity when connecting polarized
    components or test equipment into a circuit.

Safety Rules for Electronics
  • When soldering a multi-pin component, avoid
    excessive heating to one area of the component
    Do not go from pin to pin in a straight line.
  • Make sure test instruments are set for proper
    function and range prior to taking a measurement.
  • When measuring uncertain qualities, start with
    the range switch on the highest setting.
  • Always replace shields that were removed during
    service to avoid signal radiation.
  • When cutting with an X-Acto knife, avoid cutting
    towards yourself.

Safety Rules for Electronics
  • Apply heat from a soldering pencil for no more
    then a couple of seconds to avoid heat damage.
  • Keep the INTENSITY on oscilloscopes as LOW as
    possible when in use and all the way down when
    not in use to avoid burning out the screen.
  • Always OBSERVE POLARITY when connecting

    Sheet) for all chemicals prior to their use.

Do you know your safety information?
  • Remember, safety is important!
  • Most safety is common sense. Think before you
