   opportunities.
Career Opportunities
          • Union Positions, local

          • Always a need for
            skilled workers

          • More training and
            schooling means

Accidents: Causes and Results
• What Causes
  accidents?
  – Failure to
    communicate
  – Poor work habits
  – Alcohol or drug abuse
  – Intentional acts
  – Unsafe acts
  – Unsafe conditions
     Failure to communicate
• Many accidents happen because of a lack
  of communication
• Remember that different people,
  companies, and job sites do things
  differently
• Never Assume----assuming that other
  people know and will do what you think
  they should know and do can cause
  accidents!!!!!
Specific signs and markings
              • Information signs are blue
                and provide general
                information



              • Safety signs give general
                instructions and suggest
                safety measures and are
                green with white letters
                  Continued
• Caution signs tell
  about potential
  hazards and are
  yellow and black

• Danger signs tell you
  that there is an
  immediate dangers
  and are black, red,
  and white
Material Safety Data Sheet (MSDS)
• A document that must accompany any
  hazardous material. MSDS identifies the
  substance and gives exposure limits,
  physical and chemical make-up, the kind
  of hazard it presents, precautions for safe-
  handling and use, and specific control
  measures
• MSDS sheets from cleaning solutions to
  batteries for cordless drills
            Poor work habits
• Poor work habits can cause serious
  accidents.
  – Procrastination, putting off repair, inspection,
    or cleaning of equipment

  Your safety is affected by not only by how you
   do your work, but also by how you act on the
   jobsite
        Alcohol and Drug abuse
• Alcohol and drug abuse
  costs the construction
  industry millions of dollars
  a year in accidents, lost
  time, and lost productivity
• You don’t have to be
  using illegal drugs but
  over the counter or
  prescribed drugs cause
  accidents
              Lack of skill
• Be sure to learn and practice new skills
  under careful supervision

• Do not use a tool unless you were properly
  trained
Intentional Acts
        • When someone
          purposely causes an
          accident.

        • Retaliation Acts

        • Disgruntled
          Mailmen!!!!!!!
             Unsafe acts
• Failing to use Personal Protective
  Equipment (PPE)
• Using defective equipment
• Using equipment improperly
• Operating equipment at improper speeds
• Lifting improperly
• Failing to warn co-workers
            Unsafe conditions
•   Congested workplace
•   Defective tools, equipment, or supplies
•   Fire and explosive hazards
•   Poor lighting
•   Radiation exposure
•   Inadequate warning systems
  Reporting injuries and accidents,
           and incidents
• You must report all on-the-job injuries,
  accidents, or incidents, no matter how minor, to
  your supervisor
• Four leading hazard groups
  – Falls from elevations
  – Struck by accidents involve unsafe operation
  – Caught-in or caught between involve unsafe
    operations
  – Electrical shock
  ANSWER QUESTIONS
Construction site job hazards
               • This part of the unit
                 describes some of the
                 more common
                 hazards and explains
                 how to deal with them
               • Always be aware of
                 the specific hazards
                 when you are working
     Welding or use of torches
• Always keep oxygen
  away from sources of
  flame and
  combustible materials
  especially oil and
  grease
• When welding beware
  of ultraviolet rays to
  avoid flash burn
Hoses
   • Fuel hose is always
     red w/ left handed
     thread
   • Oxygen hose is green
     w/right handed
     threads
   • Be sure to check for
     leaks, burns, worn
     places, or other
     defects
                Regulators
• Attached to cylinder
  heads to lower high
  cylinder pressures to
  required working
  pressure
• Never mix
  regulators—ex :
  oxygen on acetylene
• Never use oil to
  lubricate
           Confined Spaces
• Is a space that is large enough for a
  person to work but has limited means of
  entry or exit
• Many confined spaces contain hazardous
  gases or fluids when equipment is in
  operation
  – EX: HVAC-if refrigerant leaking, especially
    lower to the ground, Plumbing-primer and
    glue fumes
Working safely with job hazards
• Lockout/tagout
  – This system safeguards workers from
    hazardous energy while working on machines
    or equipment
  – The person who puts on the tag always has
    the key
• Lock out and tag all electrical systems
• All questions about lockout\tagout contact
  supervisor
Barriers and Barricades
            • Any opening in a wall
              or floor is a hazard
              and must be guarded
            • Warning barricades
              – Red means danger
              – Yellow means caution
              – Yellow and purple
                mean radiation
   Personal Protective Equipment

• PPE is designed to
  protect people from injury
   – Hard hat

                   Cont.
• Draw the object close to your body
• Lift slowly by straightening your legs and
  keeping the objects weight as much as
  possible over your legs
• Pick object up facing the direction you are
  going to go
               Aerial work
• There are many times when workers must
  work in elevated locations
• When aerial work is done properly with
  proper equipment, it is very safe
• In the following sections you will learn how
  to use aerial equipment, inspect it, and
  how to maintain it.
Ladders & Scaffolds
          • Used to perform aerial
            work
          • When using ladder be
            sure to use three point
            contact
          • Be sure to use ladders
            and scaffolds for their
            intended use
          • Be sure not to use
            aluminum ladders when
            working with electric
Extension Ladders
         • A combination of 2
           straight ladders
         • When inspecting be
           sure rope is not
           frayed or has worn
           spots

           rungs are secured
           and rope is secure
                  Step Ladders
• Self-supporting ladders
  w/ two sections hinged at
  the top
• When inspecting be sure
  to pay attention to all the
  hinges
• Be sure to have
  spreaders completely
  open
• Never stand on top step
  or use braces as steps
                       Scaffolds
• Two types; manufactured
  and rolling
• When inspecting be sure
  to check tags for the
  scaffold for OSHA
  standards
   – Green – meets
   – Yellow – does not meet
   – Red – scaffold in process
     of being put up or taken
     down
 Hazard Communication Standard
• This is a rule that OSHA devised, also
  know as the ―Right to Know‖ requirement.
  – Requires all contractors to educate their
    employees about hazardous chemical they
    might be exposed to


• Hazardous chemicals applies to paint,
  concrete, and even wood dust
                  Fire Safety
• In order for a fire to
  start, oxygen, fuel,
  and heat must be
  present
• Must know P.A.S.S.
Classes of Extinguishers
           Electrical Safety
• Be sure that all equipment that is being
  used is properly grounded
• Always inspect electrical tools
• Never use bare electrical wire
• Never use a metal hard hat
• Always use ground fault circuit interrupter
  (GFCI) where moisture is present
       If someone is shocked
• Immediately disconnect the circuit
• If unable to disconnect circuit use a non-
  conductive object to separate victim from
  circuit
• Once victim is separated from circuit,
  apply first aid and call ambulance
