Construction Worker Safety in the Fall and Winter

Construction Worker Safety in the Fall and Winter

Although most people complain about all the construction that seems to appear during the summer months, construction (both concrete and outdoor) doesn’t stop just because the weather turns cold. And for workers who endure the cold winter months, safety becomes even more important. Working construction is always a dangerous job, but when normal working conditions are made more difficult by cold weather and decreased daytime hours, those dangers are even more present.

But that doesn’t mean that we shouldn’t work in the fall and winter, it just means that there are a few extra precautions we can take to overcome the cold and the darkness.

Overcoming the Cold

Working in the cold is uncomfortable, but not impossible. Here are a few tips to keep safe during the colder months of the year:

1. Layer—The threat of hypothermia is one of the biggest threats to winter construction safety. As a result, you need to learn the signs of oncoming hypothermia and always work in twos. Also, learn to layer your clothing so you can adjust your body temperature for different jobs and a range of temperatures so you don’t get too cold or too hot.
2. Heaters—Most companies and job sites will provide construction heaters for the winter months. There are a number of styles, like radiant heaters or forced air heaters. For example, LB White makes a wide range of heaters for construction sites that will run from wall outlets or from generators. When you use construction heaters, make sure you follow proper safety guidelines by not placing the heater too close to flammable materials or directly on plywood. When possible, elevate the heaters off the floor. And always make sure to crack a window (if working inside) in order to let out excess fumes.
3. Heating blankets—Also, if you work with concrete, make sure to use concrete curing blankets (like those made by Powerblanket), which will keep in the heat and moisture needed to help the concrete cure correctly, making it more durable and safer in the long-run.

Overcoming the Dark

Working in the cold, may be uncomfortable, but working the dark can be downright dangerous. Here are a few tips for proper lighting on the job:

1. Light towers and Light balloons—if you are working at night, in the early morning, or in the evening, lighting towers are a must. LED lighting towers are great because they provide an excellent amount of light with very little power; however, they can be bulky. For a lighter solution, you can try lighting balloons, which are more lightweight and portable. Either way, use the lighting solution that is best for your job and worksite in order to perform your job correctly and avoid accidents and injury.
2. Traffic Arrow Boards—One of the most dangerous parts of road construction is the traffic. In the dark, winter months that danger is magnified tenfold. Setting up reliable traffic arrow boards to clearly indicate where traffic should flow is a must if you are working on the roads.

All in all, construction safety in the winter is all about using the right equipment to overcome the dangers that cold and dark create. If you can use the proper equipment to keep you warm and help you see (and be seen), you’ll be less likely to get hurt or seriously injured.

As goes the Economy, so goes Construction.....

As goes the economy, so goes construction.

That industry mantra can sound either disheartening or hopeful depending on the current economic landscape.
No doubt, the recession hit hard – and few industries were hit harder than construction. In fact, in a study commissioned by Associated General Contractors, it said the recession and resulting housing and credit slump, has resulted “in one of the highest unemployment rates in any segment.”

But thanks to a slow, but steadily, improving economy, that’s all starting to change -- and it only takes a quick jaunt in downtown Salt Lake City to see the proof of the rejuvenation.

Nearly every corner of the major metro block is packed with cranes, cones and cement mixers. The city's hub is in the midst of one of the biggest revitalization projects in the nation. The story is the same for North Temple -- a revitalized shopping district and one of Salt Lake's major thoroughfares to the airport. And soon, the aptly-named 'Sugar Hole' in vintage Sugar House will become home to new retail shops and storefront luxury condos.

This trend was also confirmed on paper as, for the first time in six months, the nation’s construction industry added jobs in February. According to the March 4 employment report by the U.S. Labor Department, 33,000 jobs were created during the previous month.
But this is far from unexpected.

Fact is, buildings fall into disrepair. Roads buckle in the cold and potholes abound. As the population increases, so does the need to larger, better infrastructure and more housing options. As the economy continues to find its breath, these opportunities will grow expontentially.

So, while flurries of orange cones and traffic delays may inconvenience some commuters and pedestrians, their presence is indicative of a greater economic turnaround -- and the perennial security of the construction industry.

Let's Talk Concrete

Concrete’s versatility, durability, and economy have made it the world’s most used construction material. The U.S. uses about 260 million cubic meters (340 million cubic yards) of ready-mixed concrete each year. It is used in highways, streets, parking lots, parking garages, bridges, high-rise buildings, dams, homes, floors, sidewalks, driveways, and numerous other applications.

Specifying Cement for Use in Concrete

There are many different properties and applications of cements for use in concrete including; portland, blended, and hydraulic cements. To help determine which cement is most appropriate for your construction needs and to optimize mixture performance and economy it is important to know what is available… we’ve come along way from Joseph Aspdin’s patent in 1824!

When a cement is specified for a project, consideration should be given to the types of material available in that location. The specification should be flexible, allowing either portland or blended cements. Consideration should always be given to the use of locally available pozzolans and ground-granulated blast furnace slag, provided the desired concrete properties can be achieved. Ideally, the specification should allow any cement that meets the performance requirements of the project. Cements with special or unique properties should not be required unless absolutely necessary.

If no special properties are required

The specification should permit the use of Types I and II portland cement, blended cements, or any cement meeting the requirements of a type GU hydraulic cement. The use of pozzolans or slags should be permitted wherever possible. It may not be possible to use significant levels of pozzolans or slag (or Types S or P blended cements), in many applications because these concretes tend to set, harden, and gain strength at a slower rate, especially in cold weather.

Heat of hydration requirements –

Where moderate heat of hydration is required, Type II portland cement meeting the moderate heat option can be used, as well as a blended cement with the MH suffix, or any hydraulic cement meeting the requirements of Type MH. The temperature requirements of the concrete may also be met using other cements such as a Type I portland cement in combination with sufficient amounts of pozzolan or slag.

Low heat of hydration requirements can be met with a Type IV portland cement (although generally not produced in the U.S.). A portland-pozzolan cement meeting the low-heat option (Type P(LH) cement), or any hydraulic cement meeting the requirements of Type LH will also provide a low heat of hydration. Low heat can also be achieved by using suitable supplementary cement materials.

For more details about selecting the right cement type to prevent thermal stresses, see Portland Cement, Concrete, and Heat of Hydration (PL972).

Where sulfate resistance is required –

Moderate sulfate resistance can be provided by the appropriate portland or blended cement or by any hydraulic cement meeting the requirements of Type MS. The sulfate resistance of concrete can also be improved by the appropriate use of pozzolans or slag.

High sulfate resistance can be achieved with a Type V portland cement or any hydraulic cement meeting the requirements of Type HS. Many blended Type IS or IP blended cements will meet the requirements for high sulfate resistance, but there is no specific classification for these cements in ASTM C595. Sulfate- resistant concrete may also be met by using other cements such as a Type I portland cement in combination with sufficient amounts of appropriate pozzolans or slag.

High early strength requirements-

High early strength requirements can be met by either a Type III portland cement or a Type HE hydraulic cement. Blended cements containing highly reactive pozzolans such as silica fume may also meet the requirements for high early strength, although there is no specific classification for such a cement in ASTM C595.

Resistance to ASR-

When a potentially reactive aggregate is being used some level of protection against damaging ASR expansion may be achieved by specifying either the low-alkali option for portland cement, the option for low-reactivity with pyrex glass for blended cements, or by specifying any type of hydraulic cement that meets option R (which is also based on a performance test using pyrex glass). Resistance to ASR may also be conferred on a concrete by incorporating sufficient amounts of appropriate pozzolans or slag.

Some types of portland cement may not be readily available in all areas. Type I portland cement is usually furnished when a specific cement type is not specified. Type II cement is usually available, especially in areas of the country where moderate sulfate resistance is needed. Cement Types I and II represent about 90% of the cement produced. Some cements are designated as both Type I and II (Type I/II), meaning that they meet specification requirements for both types. Type III cement and white cement are usually available in larger metropolitan areas. Type IV cement is manufactured only when specified for particular projects (massive structures like dams), and therefore is usually not readily available. Type V cement is available only in particular regions where it is needed to resist high sulfate environments.

Blended cements are available in many regions of the United States but certain types may not be available in some areas. The properties conferred on concrete through the use of blended cements can usually be attained by combining normal portland cement with appropriate levels and types of supplementary cementing materials at the mixer.

When cements with special properties are not available, adjustments to the proportions and types of material in the concrete mixture can usually be made to attain the desired properties using available materials.

Fitting a Traffic Arrow Board to Your Full-Size Pickup

Traffic Arrow Boards are an important part of construction site safety, particularly in the case of road and highway construction. Arrow boards come in a variety of styles and sizes to meet the needs of any job. From towable towers to mountable truck units, each can be very useful in the field. If you're considering a truck-mounted unit, you may have some questions about how the board will integrate with your current set up. 

Basically, there are four ways you might mount a board to your current vehicle: Tailgate Mount, Bed Rail Rack, Bed Floor Rack, and Bulk Head Rack. I've posted images of each style below for you to review.

 
  As you can see, each of these mounting options can accommodate a variety of situations. Generally a full-size pickup with a regular, enclosed bed would use either a bed rail rack or bed floor rack system to mount the arrow board properly. Utility, sewer, dump, and other heavy-duty commercial motor vehicles will generally require a tailgate style mount or a bulk head mount. Each of these mounting styles can be purchased in a manual tilt or power tilt option. The power tilt arrow board allows you to control the board's tilt from the cab of your truck. Some applications find this feature very necessary, and others that are price conscious or have a tailgate mounted unit don't find it to be a necessity at all. It generally will come down to preference. However, I would recommend a power tilt unit almost 100% of the time. Keep in mind, any time it's unsafe for an operator to get out of their vehicle to deploy a board roadside, a power tilt becomes very handy. Don't skimp on price early only to regret your decision on the road with cars flying by at 75 mph! 

Because mounting an arrow board can be confusing and would be difficult to do on your own, Trafcon Industries has created several standard kits for full-size pickups. This includes both bed mounting options. The mounting kits included with either bed option, rail or floor, are capable of fitting any full-size pickup. So whether you have a Ford F-250 or a Chevrolet Silverado 2500, you'll be set with the Trafcon units.  If you have any questions about specific models, capabilities, or installation, please leave a comment below.
