37. Slide 37

    WHY INTERNAL

    • TRAFFIC CONTROL?
38. Slide 38

    ITCPs Protect Workers on Foot

    • Workers on foot are those employees who perform most of their duties outside vehicles and equipment. They are particularly vulnerable to being struck by equipment. Every person on the site has the responsibility to be vigilant and work safely
    • Require all workers to wear Hi-viz apparel
39. Slide 39

    Two “Struck-By” Hazards

    • Workers Killed by Motorists
    • Workers Killed by Construction Trucks and Equipment
    • MORE WORKERS ARE KILLED BY CONSTRUCTION VEHICLES THAN BY MOTORISTS
40. Slide 40

    Work Zone Crashes

    • Work Zone Crash Frequency
    • On average, in 2015:
    • A work zone crash occurred once every 5.4 minutes
    • Every day, 70 work zone crashes occurred that resulted in at least one injury
    • Every week, 12 work zone crashes occurred that resulted in at least one fatality
    • Crash Severity
    • In 2015 the distribution of work zone crashes by severity included:
    • 73.0% (70,499) of work zone crashes were Property Damage Only (PDO)
    • 26.4% (25,485) of work zone crashes involved at least one injured party
    • 0.7% (642) of work zone crashes involved at least one fatality
    • This distribution is very similar to non-work zone crashes.
41. Slide 41

    Construction Vehicles are the Greatest Hazard

    • Compliance with the MUTCD and OSHA regulation is a necessary
    • The interaction between workers on foot and construction trucks and equipment is the single biggest hazard
    • There are several hazards workers should be aware of to enable them to protect themselves against work zone hazards
42. Slide 42

    Vehicles Frequently Enter and Exit

    • The constant movement of vehicles can create hazards
    • ITCPs can communicate the need to keep entry and exit points free
    • Start each day with a risk assessment discussion with workers and subcontractors (including employees)
43. Slide 43

    Workers on Foot Labor in Close

    • Proximity to Large Vehicles
    • Note the size of workers on foot in relation to the size of the construction equipment and vehicles.
44. Slide 44

47. Slide 47

    SITUATIONAL AWARENESS – INCIDENT PREVENTION

    • Stay focused
    • Mind on Task
    • Keep your eyes and ears open
    • Eyes on Task, Line of Fire, Balance/Traction/Grip
    • Identify & assess new hazards as you see them
    • Be aware of change and stop to re-assess
    • THINK BIG PICTURE
    • Communicate with the team and others
    • If in doubt stop the job and re-assess
48. Slide 48

    Key Elements

    • Perception
    • Gathering or collecting information

49. Slide 49

    What is a “hazard”?

    • practice
    • condition
    • An unsafe ___
    • or ___
    • injury or ___
    • illness
    • that could cause an ___
    • to an employee.
    • How can a person be a walking hazardous condition?
50. Slide 50

    Mistakes / Errors

    • When employees make mistakes increasing the risk of injury it is usually because they were either rushing, frustrated, fatigued or complacent.
51. Slide 51

    CONDITIONS

    • Mind Sets
    • Hurried
    • Angry
    • Tired
    • Complacency
    • Mistakes
    • Eyes not on task
    • Mind not on task
    • Line-of-fire
    • Balance, traction, grip
    • Over 90% of all injuries at home, at work or on the road are caused by these error patterns.
52. Slide 52

    States of Mind

    • Hurried - When you exceed the pace at which you normally perform the task
    • Angry - Caused by relationships inside and outside of the workplace
    • Tired - Too tired to do the job safely
    • Complacency - Familiar enough with the hazards to become considerably less concerned over time
53. Slide 53

    Critical Mistakes

    • Anyone can get hurt if they are not looking at what they are doing/paying attention
    • While this may appear to sound like “common sense”, unfortunately common sense is not always common practice
54. Slide 54

    Eyes not looking at what you’re doing

    • Not looking where you are going or what is coming your way. Includes not moving your eyes before moving your body or not being able to see where you are stepping, where your hands are reaching into, etc.
55. Slide 55

    Not thinking of the job

    • Not concentrating on the job. Being unaware of dangers. Forgetting things, making more errors than usual, going on “auto-pilot”, “drifting away”.
    • What time do I get the kids?
    • Why can’t I break 100 for 18 holes?
56. Slide 56

    Standing in the Line-of-Fire

    • Being conscious of where you are or where you are going in relation to the direction of the hazard.
    • If the driver doesn’t see me, where does the vehicle go?
    • Which way will the drunk drive?
57. Slide 57

    Balance/Traction/Grip

    • Doing something that could cause you to lose your balance, traction, or grip. This can include not wearing good footwear/gloves, not having a good grip in the first place, or not seeing or thinking about the hazard.
58. Slide 58

    Workers Killed by Motorists

    • As noted previously, the primary cause of worker deaths in roadway construction is caused by workers being struck by construction vehicles and equipment.
    • The second highest cause is workers being struck by motorists or when a vehicle crashes.
59. Slide 59

    Two Ways Workers Are Killed by Motorist

    • Workers Enter the Traffic Space
    • Motorists Enter the Work Space
60. Slide 60

    Workers Killed

    • Motorists are likely to enter the work space when:
    • Workers are not visible to motorists
    • Motorists are surprised by the work zone and Temporary Traffic Control set up
    • Motorists ignore warnings
    • TTCDs are confusing/not compliant
61. Slide 61

    Killed by Motorists

    • Motorists are likely to enter the work space when:
    • Drivers are distracted or impaired (phones, food, drugs, alcohol, drowsy, etc.)
    • Traffic is traveling at high speed through the work zone
    • Equipment / work zone lighting
62. Slide 62

    Risky Worker Behavior

    • Workers stray into traffic space
    • Preoccupied by work
    • Become “comfortable” in dangerous environment
    • No convenient access to and from work space
    • rest rooms
    • food and water
    • shade/breaks
    • other local work areas
    • staging of company and personal vehicles
    • Workers cross traffic lanes (especially in high-speed locations)
63. Slide 63

    How Can We Prevent Deaths Caused by Motorists?

    • Temporary Traffic Control Devices Must be Set Up Properly
    • Comply with MUTCD or corresponding state document
    • Inspect and maintain TTCDs
    • Ensure only a qualified person makes necessary modifications
    • Create Safe Procedures for Deployment and Retrieval of TTCDs
    • Ensure sufficient TTCDs for all parts of the project (ramp geometry, exits, closures, etc.)
64. Slide 64

    How Can We Prevent Deaths?

    • Workers Should Be Aware of TTCDs in their work location.
    • Workers should be trained to notify supervisor immediately if devices are:
    • Not in proper position
    • Damaged or dirty
    • Not being observed or recognized by motorists
    • Workers may correct misaligned devices if it is safe for them to do so and they understand where the device is supposed to be situated.
65. Slide 65

    Workers Should be Aware of Basic TTC Rules

66. Slide 66
