Uniform – Garment Classes
Three
classes of high-visibility safety
apparel.
Garments
that cover the torso, such
as safety
vests, are intended to meet Class 1 or Class 2 requirements.
Class 3 covers full
bodySlide8
Class 1 Garments
Intended for use in activities that permit the wearer’s full and undivided attention to approaching traffic. There should be ample separation of the worker from traffic, which should be traveling no faster than 25 miles per hour.
Parking lot
attendants; People
retrieving shopping carts from parking lotsSlide9
Class 2 Garments
I
ntended for use in activities where greater visibility is necessary during inclement weather conditions or in work environments with risks that exceed those for Class 1 or perform tasks that divert their attention from approaching traffic, or that put them in close proximity to passing vehicles traveling faster than 25 mph.Slide10
Class 3 Garments
T
he highest level of visibility in the ANSI standard, and are intended for workers who face serious hazards and often have high task loads that require attention away from their work. Garments for these workers should provide enhanced visibility to more of the body, such as the arms and legs.Slide11

Driver Expectancy
Stopping Sight Distance
The distance traveled from the time a driver first detects the need to stop until the vehicle actually stops.
Two Components
Perception/Reaction Distance
Braking/Skidding DistanceSlide14
Perception/Reaction Distance
Distance travelled by a vehicle from the instant a driver sees an object to the instant the brakes are applied.Slide15
What’s the Typical Driver’s Perception/ Reaction Time?
0.5 seconds
1.0 seconds
1.5 seconds
2.0 seconds
2.5 seconds
4.0 seconds
Be prepared for drivers who don’t stop…
As much as 2.5 secondsSlide16
Perception/Reaction Time
At 60 mph, how far will a car travel during perception/reaction time?
60 mph = 88 feet/second
In 2.5 seconds,
Distance = 220 feetSlide17
A vehicle will travel the following distances in 2.5 seconds…

Flagger Fundamentals
Primary function is to provide safety for incident response personnel, motorists and pedestrians traveling through area.
Flaggers are responsible for life safety.
Flaggers must stop traffic intermittently and maintain flow at reduced speeds.Slide24
Flagger Fundamentals
Flagger must be CLEARLY seen by:
Standing out from the background
Standing at a distance sufficient to permit driver response and speed reduction timeSlide25
Flagger Position
Primary concern of your safety!
Visible
In advance of incident area or at intersection
Away from roadway obstructions – uncluttered.Slide26
Flagger Position
Use shoulder adjacent to traffic.
In intersection, stand in center of intersection only if accompanied by professional.
Have escape route
Stand alone (unless working in tandem)
Face oncoming traffic
Watch for turns
Above all, be seen and be safe!Slide27
Hands, Tools and Gear
In traffic control you may use:
Hand signals
Whistles
Voice commands
Flashlights, flares
Cones, barricades
Or even a vehicleSlide28
Hand Signals
Art of the Hand Signal
Make eye contact with the driver
Give only one direction at a timeSlide29
Hand Signals
STOP
Point – arm and finger extended – look straight driver
Hold until driver sees
Raise pointing hand so palm is toward driver
Hold this position until driver stopsSlide30
Hand Signals
STOP two directions
Stop traffic coming form one direction first
Hold hand in stop position, turn to other side – repeat
Don’t lower either arm until both lanes have stoppedSlide31
Hand Signals
START
Place yourself so one side is toward traffic to be started:
Point with arm and finger toward first car
With palm up, swing hand up and over chin, bending arm at elbow
After traffic starts from one side, turn to other side and repeatSlide32
Hand Signals
KEEP MOVING
Continue using same hand signal for slow or timidSlide33
Hand Signals – Turns
Stop traffic in lanes car is to cross
Left Turn:
Give stop signal with right arm to stop traffic in lane being crossed
Hold stop signal with right arm and give turning gesture with left arm
Right Turn:
Turn around to face in direction car is to go
Halt traffic with right arm and give turning gesture with left armSlide34
Hand Signals
In a intersection with only one lane in each direction:
Left turners can block traffic
While driver is waiting, signal driver into middle of intersection
Point at driver, motion to move forward and point to place where you want them to stop
Permit left turn when safeSlide35
The Whistle
Who keeps a whistle in their CERT Gear?Slide36
The Whistle
Whistle use:
One long blast with
“stop”
command
Two short blast with the
“start”
command
Several shot blasts to get the
“attention
” of a driver
A short, intermittent, blast to
“keep the traffic moving”Slide37
Voice Commands
Seldom heard in traffic
Hand signals and whistles are most efficient
Shouted orders may antagonize a driver
When a driver or pedestrian don’t understand a command, move closer to them and explainSlide38
Flashlights
Flashlights can be used to direct traffic at night
Flashlights with colored extensions work for evening, foggy or rainy weatherSlide39
Flashlights
Direct Traffic
Halt Traffic
Don’t stand directly in front of approaching
vehicle
Swing the flashlight at arm’s length across the path
of the approaching vehicle
Avoid
blinding the driver with flashlight beam
Allow flashlight beam to wash across the pavement as an elongated moving spot
Use a traffic cone
to enhance safety
Once traffic has stopped, step in front of car and guide next lane of trafficSlide40
Flares
Flares can be used to warn oncoming traffic in situations where hazards are:
On shoulder or side of road
In a traffic lane
Night or daySlide41
Flares
DO NOT USE:
Around flammable liquids or solids
In a hazardous environmental areas such as dry grasses
Do not lay against traffic dots or on top of painted lane markingsSlide42
