Safety
  • Engineering Lab Safety

By Christie Schmitt
2
Essential Questions
  • Why is lab safety important in your engineering
    lab?

3
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
Injury
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.

6
Basic Safety
  • Always clean up sawdust it can be just as
    slippery as a spilled liquid, oil or grease.
  • Dont use screwdrivers as chisels or pry bars.
  • Never carry sharp tools in your pockets.
  • Wear suitable clothing. Remove or fasten loose
    clothing, neckties, or jewelry. Roll loose
    sleeves to elbows.
  • Dont work with oily or greasy hands.
  • Plan your work before you start. If youre
    cutting a large piece of wood, ask for help
    before you start cutting. Dont wait until youre
    in trouble.
  • Secure all small work short work in a vise or
    with a clamp.

7
Basic Safety
  • Dont pry or hammer with a file. It may shatter.
  • Securely fasten long hair or hair styles that
    could create a hazard, or wear a hair cover.
  • Handle all sheet metal carefully. A metal edge
    can be as sharp as the tool which cut it.
  • Handle sharp-edged tools pointed tools with
    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
    properly.

8
Basic Safety
  • Report all injuries, no matter how slight, when
    they occur. Even if it doesnt seem serious, it
    can become infected days later if not properly
    treated.
  • Wear the proper safety equipment for the job.
  • Keep the aisles clear. Dont leave extension
    cords where someone could trip over them. If they
    must go across an aisle, fasten them to the
    floor.
  • Place oily rags other combustible materials in
    approved metal containers.
  • Cut away from yourself when you use chisels and
    other edged tools.
  • Dont distract or crowd around people while
    theyre working.

Safety Rules for Hand Tools
  • Always wear eye protection.
  • Wear the right safety equipment for the job.
  • Use tools that are the right size and right type

  • Follow the correct procedure for using every
    tool.
  • Keep your cutting tools sharp and in good

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
    together.
  • Use a heat sink when soldering temperature-sensiti
    ve components.
  • Never solder a circuit that has the power
    applied.
  • 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.

17
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.

  • 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
