Title: CONSTRUCTION SITE SAFETY An office worker


1
CONSTRUCTION SITE SAFETYAn office workers
overview of construction site hazards
  • May 20, 2009 J. Manning

2
HAZARDS
  • Physical hazards (slips, trips, falls, falling
    objects, pinch points and snags)
  • Hazardous substances
  • Environmental (Heat/cold, Noise)
  • Machinery and tools
  • Confined spaces
  • H2S (Hydrogen Sulfide)

3
Identification of hazards
  • FLRA (Field Level Risk Assessment)
  • A way to manage risks and hazard on the job as
    per the Construction Owners Association of
    Alberta.
  • Identify hazard
  • Assess the risks
  • Control the risks

4
Spot the hazards Hint there are at least 5
PPE not being used
Trip hazard
Open hole
Confined space
Not using railing/ladder
5
Physical hazards
  • Slips, trips and falls be aware of your
    surroundings, wear appropriate clothes/shoes/gear.
  • Be aware of open holes and ditches. Areas marked
    hole.
  • Stay fit, to be able to do the job.
  • Falls fall protection and fall protection
    training required (2m and above)
  • Use a rope or hoist to carry tools up a ladder.
  • Falling objects be aware of people and objects
    above you.
  • Pinch points areas where you can get limbs or
    body parts caught. Snags ensure clothing doesnt
    get caught. Note if you cant see where you are
    putting a hand or foot, dont put it there.
  • Use rails and handholds
  • Scaffolds be aware of tagging. Red dont use,
    Yellow caution, issues, Green safe to use.

6
Chemical hazards
  • Know your WHMIS symbols
  • Follow directions, by supervisor and on the
    labels
  • Use PPE
  • Be mindful of spills
  • Wash your hands before eating or smoking if
    youve been handling
  • chemicals.

7
Environmental hazards
  • Dress appropriately for work
  • Know the signs of frost bite, hypothermia and
    hyperthermia
  • Use noise protection PPE where appropriate
    (lawnmower level and above)
  • If outdoors, get informed about the weather
  • Be cautious around bodies of water

8
Machinery and tools
  • Be aware of your surroundings, wear traffic vests
    where appropriate.
  • Watch out for the turning radiuses of large
    vehicles and swing radiuses of heavy machinery
    (cranes, backhoes etc.). Keep a line of sight and
    stay well back.
  • Welding torches dont stare directly at them
  • Be aware of hearing damage from loud machinery
    and tools
  • Learn how to properly use tools before using them
    and the wear the appropriate PPE when around
    items such as chain saws, power tools, welding
    torches, air tools and explosive charge tools.
  • Special training for air tools, explosive charge
    and impact tools.
  • Be aware of dangerous equipment. If it tagged,
    then dont use. Be aware of equipment where
    safety guards have been removed, grounding pin
    has been removed or cords are frayed.

9
Spot the hazards Hint there are at least 3
Falling object risk
Not using fall protection PPE
Falling object risk
Pinch point
No line of sight w/forklift driver
10
Confined spaces
  • Know what a confined space is.
  • Be certified before entering a confined space
  • If someone collapses for no reason, dont
    immediately rush in after them in a confined
    space.
  • PPE can include gas detectors and sometimes
    safety harnesses
  • With excavations, there should always a second
    way out/ladder out.

11
H2S (Hydrogen sulfide)
  • Colorless, toxic and flammable gas that in low
    quantities can smell like rotten eggs. In high
    quantities, it is odourless.
  • Heavier than air and tends to accumulate in
    confined spaces.
  • Byproduct of oil/gas impurities, volcanoes,
    swamps and sewers.
  • Can be found at wellsites, refineries, and in
    many areas oil/gas companies operate.
  • Before working in areas where this gas is known
    to be present, H2S training is usually required.
    Ex H2S Alive.
  • PPE for H2S can include gas detectors and SCBA
    (self-contained breathing apparatus).

12
Take away
  • Be aware of your surroundings
  • Conduct Field Level Risk Assessments. Identify
    hazards then eliminate, avoid or minimize them
  • Get trained for the job and the jobsite hazards
  • Wear PPE
  • THANK YOU FOR YOUR TIME.
