Delineators - Traffic Delineators

Delineators 101

Delineators are used in many different ways. Because they are lightweight and easy to move and store, they are a great option for temporarily redirecting traffic, blocking areas and temporary road closures.  Unlike Bollards which tend to be heavier and used more as an obstruction to traffic and to protect from ramming, delineators are lighter weight and serve a more visual capacity to help direct traffic.  However, they are still sturdy and their flexible material will withstand impact if needed though they might not stay upright.

There are different versions of delineators. One of the most common is the simple open top delineator which is highly visible and portable. They can be purchased with or without reflective bands.  The ring top delineator and claw delineators are similar but have an opening at the top to allow for use of caution tape with the delineator.  The caution tape can either be held in the claw or wrapped around and through the ring.

One of the popular delineator models is the DP 200 Series post which is a 3-inch round channelizer made of polyurethane. Polyurethane is the toughest flexible plastic available and is extremely flexible. Even at extreme temperatures it returnsto an upright position after impact. The DP 200 posts are highly visible both day and night and help to delineate driving lanes with bright colors and reflective sheeting.  It has been NTPEP tested and meets the requirements of NCHRP 350 for Category 1 Devices.

The most important things to look for in selecting delineators is durability and visibility.  All the delineators at Traffic Safety Warehouse meet MUTCD (Manual on Uniform Traffic Control Devices) standards. If you need help in determining the best traffic control device for your project, give us a call and we will be happy to help you.

Types of Barricades

Traffic barricades (also known as safety or road barricades) are used to control the flow of traffic in a specified area. They are used at construction sites, accident scenes, as roadblocks, at schools and in a variety of other crowd control situations. There are many different types of road barricades in varying sizes, weights and strengths. So it is important to choose the type of barricade that will best serve your needs. This is a quick traffic barricade overview for those who are just getting acquainted with the types of barricades and their uses that we hope you will find helpful.

Type I BarricadesType I Barricades

The Type I Barricade is so named because it has only one reflective rail. Typically it is at least 24 inches wide with orange and white stripes alternating at a 45 degree angle. Sometimes, a second non-reflective rail is added to help give it a more stable base of support. Often Type I Barricades are used for pedestrian traffic control and are used on low speed roads.

Type II BarricadesType II Barricades

Type II Barricades have two reflective rails, also with alternating orange and white stripes. Because the bottom portion of the barricade is also a reflective surface, these generally offer better visibility at night than the Type I Barricades. These barricades also meet the requirements for use on expressways or other higher speed roads.

Type III BarricadesType III Barricades

Type III Barricades are larger and have (yes you guessed it) three reflective panels with alternating orange and white stripes. They are at least 4 feet wide (or larger) and are most often used for road closings because of their size and visibility. You have seen these types of barricades positioned across roadways for detours, road closing and other types of traffic control.

A-Frame BarricadesA-Frame Barricades

A-Frame Barricades typically include a pair of A Frame barricade legs plus a two-sided reflective barricade board. Often they are used to keep a safe distance for workers or pedestrians on roadway work sites or for events needing crowd control.

Traffic Barrels - ChannelizersTraffic Barrels

Traffic Barrels (also referred to as channelizer drums) are also used at construction sites and have alternating white and orange reflective bands. They typically have a rubber base that helps them to remain upright during strong winds or when hit by a vehicle. Most have a handle on top for easy pick up and carry as well as to provide a place to place a barricade light for increased visibility at night.

Retroreflectivity & Sign Visibility

Sign visibility in construction, school and pedestrian zones has always been a big priority for increasing safety. With advances in technology, there are better options available to help decrease the likelihood of accidents.  To understand reflectivity and visibility, it is helpful to understand a few important terms first.

Sheeting – is the  front of the sign that is attached to the substrate.  The sheeting helps determine both the retroreflectivity and the sturdiness of the sign. The majority of traffic signs are required to be reflective according to the the Manual on Uniform Traffic Control Devices (MUTCD) and OSHA.

Retroreflectivity – retroreflectivity is a measure of a materials’s a ability to reflect light back to its originating source and affects the visibility of the sign it’s used on.  Engineer grade reflective was once the standard for sheeting material on reflective signs but new FHWA regulations have replaced this material with materials like High-Intensity (Prismatic) Reflective and Diamond Grade Reflective. Prismatic reflective sheeting meets all of the FHWA, MUTCD and OSHA requirements. Diamond Grade Reflective is now the standard used when very high retroreflectivity is needed to ensure greater visibility.  Hilly roadways, roads with sharp turns and/or really dim lit roads are all candidates for this type of sheeting material.

Traffic Safety Warehouse carries a huge assortment Engineer Grade products,  High Intensity Prismatic Sheeting products  and Diamond Grade Sheeting safety products including barricades, channelizers and diamond grade tape.  If you have questions concerning which is the most appropriate grade for your project, just give us a call.

OSHA Rebar Caps

Rebar can be found on almost every construction site.  It is used to help keep the cement stable and improve the structural stability of the concrete. Unfortunately, the protruding rebar can be extremely dangerous. Employees or pedestrians that fall on exposed rebar can be seriously injured or even killed so OSHA has come out with standards for rebar caps to help keep the construction zone safer for everyone. OSHA requires that any exposed rebar be covered by rebar caps.  Traffic Safety Warehouse offers OSHA Rebar Caps made of space age high density polymer to protect against impalement injuries.  These rebar caps meet new OSHA requirement 344.90. Besides their sturdy protective surface they are also made in high visibility colors like lime green and orange to further enhance safety.

We also carry the more standard mushroom rebar caps which have a mushroom shaped surface and also come in high visibility colors. These rebar caps are to be used only where danger of impalement doesn’t exist. You can find all the rebar cap offerings with our facility safety products >>

Wheel Chocks

Wheel chocks , also called wheel stops or wheel blocks, come in a variety of sizes and shapes and can be made from different types of materials. They are used to prevent a vehicle from rolling forward or backward.

Wheel chock uses:

Wheel chocks are used to keep a vehicle from rolling when the opposite end is lift. Wheel chocks are also often used with large, parked trucks to ensure the vehicle doesn’t roll and cause damage to property.  Off road chocks can be used in construction when builders need to park in areas that do not have roadways yet and the land is uneven.  Additionally, airplanes use wheel chocks to keep them from moving from their parked spot.

How to use wheel chocks when lifting a vehicle:

1) Park the vehicle on a level surface.

2) Set the parking break

3) Figure out which way the car would roll if you were to lift up the end you are planning to lift.

4) Place the chock between the ground and the back end of the wheel (furthest away from the side you are lifting).  Then kick the chock toward the wheel to make sure it is securely in place.

5) Place a second chock on the front end of the same wheel and again, kick it toward the wheel to make sure it is secure.

6) For maximum safety, secure the second wheel on that end of the vehicle the same way. So if you are lifting the front of the vehicle, you would be placing wheel chocks on the back two wheels.  If you are lifting the back end of the vehicle, you would be placing chocks on the front two wheels.

Buying Wheel Chocks:

 Traffic Safety Warehouse carries a variety of wheel chocks including:

Barricade Safety – Striping and Sheeting

Have you noticed that traffic barricades have stripes that either slope down to the left or to the right? This is to meet the requirements stated in the Manual on Uniform Traffic Control Devices which specifies that traffic barricades must have alternating orange and white striping which slopes down in the direction that traffic is expected to pass on. So a ‘Right Barricade’ would be placed on the right and the striped would be sloped upward at a 45 degree angle. A ‘Left Barricade’ would be placed on the left and the stripes would be sloped downward at a 45 degree angle.

Plasticade has a variety of barriacdes with sheeting  which allows easy switching out of the stripes so that it can be used as a ‘left’ or ‘right’ barricade as needed. Plasticade barricades are also made of very durable plastic which can stand up to weather and traffic.

Parking Cones - Traffic Cones

Parking Cones

Parking cones, also referred to as traffic cones or road cones come in several sizes and have many uses.  They range from 4  inches to 42 inches in height. The most commonly used parking cone sizes are the 28″ traffic cone and the 12″ traffic cone.  Traffic cones are very durable so they can withstand impact with cars and weather.

Parking cones can be used in construction zones for diverting traffic, for dividing lanes or used as parking devices. For use in construction zones and other traffic control, the 28″ traffic cone is generally the best choice because of their greater height and visibility. For city streets, the minimum acceptable height for traffic cones is 18 inches.

12″ traffic cones which are often used for in parking lots, for marking off play areas for kids, or as temporary barricades in indoor settings.  The smaller cones like 6″ parking cones are often used in sporting events.

Cones that are to be used in night settings must have a reflective collar.

Safety Wear

The spring and summer seasons are also road construction seasons and keeping workers safe is high priority.  Many people have questions about which safety wear is needed for what jobs and what requirements the safety wear needs to meet.   ANSI/ISEA  is a voluntary industry standard which  specifies the requirements expected for high-visibility safety wear for construction workers, utility workers, landscaping, and fire fighters.

There are many different types of safety wear including safety headware, safety vests, safety pants, jackets and shirts.  Depending on the type of work being performed, persons in construction or otherwise high traffic areas should be aware of the the three levels of high visibility apparel standards.

Class 1 Safety Wear: Appropriate where there is plenty of separation of workers from vehicle traffic and where the work area is not complex.  Additionally, traffic speeds are not expected to exceed 25 mph in these areas. This class of safety wear are often seen on parking service personnel, warehouse staff, and those doing shopping cart or sidewalk maintenance.

Class 2 Safety  Wear:  Appropriate when work activities take place closer to traffic and where these activities may divert worker attention from approaching traffic with speeds exceeding 25 mph. The Class 2 safety apparel is often seen in greater than 25 mph construction zones, parking and tollway personnel, school crossing guards, airport grounds personnel and those directing traffic.

Class 3 Safety Wear: Appropriate for workers who are exposed to higher vehicle speeds and/or reduced sight distances.  The worker must be visible throughout body movement and must be identifiable as a person at a distance of 1,280 feet away.  These garments provide the best visibility with lots of extra reflective surface and they must have sleeves with retroreflective material between the shoulder and arm to make movement more noticeable.   These are often used by railway workers, roadway construction staff, vehicle operators and accident site investigators.

There are several different colors to choose from when it comes to safety wear.  The flourescent yellow green is thought to be the most visible color for dusk and dawn when there is less light.  It can also provide some contrast for those in work zones with orange traffic cones and safety equipment.  The flourescent orange color is also a very popular color and has good contrast for areas that have more foliage.  This is typically the safety color in work zones.  However, if you are trying not to blend in with a plethora of other orange safety equipment then as stated above, the flourescent yellow green may be a better choice.
