• 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
• MSDS sheets from cleaning solutions to
  batteries for cordless drills
            Poor work habits
• Poor work habits can cause serious

  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
  – Electrical shock
Construction site job hazards
               • This part of the unit
                 describes some of the
                 more common

     Welding or use of torches
• Always keep oxygen
  away from sources of
  flame and
  combustible materials
  especially oil and
• When welding beware
  of ultraviolet rays to
  avoid flash burn
   • Fuel hose is always
     red w/ left handed
   • Oxygen hose is green
     w/right handed
   • Be sure to check for

           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
  – 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
Barriers and Barricades
            • Any opening in a wall
              or floor is a hazard
              and must be guarded
            • Warning barricades

  keeping the objects weight as much as
  possible over your legs
• Pick object up facing the direction you are
  going to go

  w/ two sections hinged at
  the top
• When inspecting be sure
  to pay attention to all the
• Be sure to have
  spreaders completely
• Never stand on top step
  or use braces as steps
• Two types; manufactured
  and rolling
• When inspecting be sure
  to check tags for the
  scaffold for OSHA
   – Green – meets
   – Yellow – does not meet
   – Red – scaffold in process
     of being put up or taken
 Hazard Communication Standard
• This is a rule that OSHA devised, also

• 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
• Once victim is separated from circuit,
  apply first aid and call ambulance
