• Calibrate separately for salt/sand mix vs. salt or sand only. • Determine flowrate or calibrate liquid application systems at the same time as the dry systems. • Remember: Theauger plate must be in place during cali-bration. You are not calibrating the truck properly if the material is gravity-flowing. Oct 23,  · Key testing variables identified were: surface temperature, melter type and application rate. To address each variable, the team selected surface temperature ranges to measure melting performance in extreme and average winter temperatures using sodium chloride (rock salt), calcium chloride, calcium chloride/rock salt blend and magnesium chloride. Proper application rates are essential for effective road treatment and reducing wasted time, effort and money.

Know the calibration of your salt spreader to use the correct amount for the job. Ice control on parking lots requires some capital investment. While a truck is needed, it does not necessarily need to be a truck outfitted with a plow. In fact, there are some compelling arguments that having a truck plow and salt is not an effective use of resources. The initial venture into deicing services begins with the acquisition of a tailgate-mounted, electrically driven spreader holding to lbs.

The downside to this method of deicing parking lots rock salt application rate driveways is the deicing material must be manually loaded into the hopper, thus requiring someone to work outside in the elements several times during a typical evening plowing.

Generally, the material is loaded onto the truck in or lb. While inefficient from a labor standpoint, margins are still much higher than plowing. The next step in building your deicing service is to purchase and mount a slide-in, V-box spreader, rock salt application rate.

These spreaders are hydraulically or electrically driven units that hold from 1, rock salt application rate. Some manufacturers make units that fit nicely on a three-quarter ton pickup, but care must be taken not to overload the hopper. The additional weight can cause rock salt application rate with the truck's suspension, causing damage to the undercarriage and axles of the vehicle.

Once the spreader is mounted on the truck, whether on the tailgate or as a V-box, it is filled with salt and the mechanism turned on, spreading the salt while the truck drives over the pavement. Most spreaders are equipped with mechanisms that allow the operator to control the amount of salt being applied.

Once the operator determines how wide the salt path is, he or she can determine how many passes are required to coat the entire lot with salt or deicing product. As your company continues to grow, using spreaders mounted on the rear boom of a backhoe can also reduce labor costs since a single operator with a pusher on the front of a backhoe can clear and deice the lot simultaneously, rock salt application rate. Anti-icing Deicing is the most common means of removing ice from a customer's facility or residence.

Deicing is the application of an ice-melting material after ice has formed on the pavement, sidewalk or other traffic area. However, you can apply salt or an alternative deicing product prior to the snow or ice event.

This technique is called anti-icing and it has grown in popularity, especially among contractors using liquid deicing materials. Salt, sitting on the paved surface, is inert unless moisture is introduced and comes in contact with the granular rock salt. Once it starts to snow, the moisture causes the salt to dissolve into solution.

The resulting salt brine prevents ice and snow from bonding with the pavement surface. Since no bonding takes place, once plowing operations commence the snow or slush is easily removed. This leaves a cleaner surface than if you plow the site after the snow and ice has bonded to the pavement. The nice thing is you can achieve this result by using only one-third the amount of product required for traditional deicing. If it does not continue to snow after completion of plowing operations, there is often no need to reapply salt to the cleared surface.

If an additional application of salt is required, desired results can be achieved with considerably less material than you would have needed had you not been proactive. All things considered, the astute contractor can actually use half the normal amount of salt by having a pre-salting program in place.

Most contractors who pre-salt also make a very light application of salt after the plowing has been completed. How much is enough? Establishing a pre-salting program can conserve salt usage in the long run. When discussion occurs about the use of rock salt sodium chloride and its distribution to the pavement rock salt application rate, there are always arguments as to how much product needs to be applied to the pavement surface to achieve rock salt application rate desired results.

Don Walker from the University of Wisconsin, one of the leading authorities on deicing in the country, stated that lbs. Various DOT studies indicate that in a light-icing situation, to lbs. Under these conditions, the melting process will take 45 to 60 minutes to complete.

A heavy accumulation of ice may require as much as lbs. This may seem absurdly low, but these low application levels are attainable. In fact, recent studies indicate as little as 75 lbs, rock salt application rate.

Unfortunately for contractors, the V-box, rock salt application rate, slide-in spreaders can only be calibrated down to about lbs. There are spreaders on the market that can go as low as 75 lbs, rock salt application rate. Normally, this is out of a commercial plowing contractor's price range. Contractors often charge for half-ton and full-ton applications of rock salt for an acre of parking surface. More often than not, rock salt application rate, contractors apply more salt than is necessary.

This has some negative consequences, including reduction of profits, the potential to overcharge customers rock salt application rate doing more harm to the environment than is necessary. The next time you see a white parking lot the day after a snow storm, it is likely rock salt application rate contractor over applied salt to the lot.

I'm always perplexed when I am with a snow contractor and he tells me how his company is getting "double duty" out of his trucks by having them equipped with snowplows and salt spreaders.

Leaving aside the weight issue associated with all that steel sitting on or attached to the truck, the financial side of the equation begs that a contractor takes a closer rock salt application rate at revenue generation for this critical piece of equipment. It means taking a one-ton pickup truck that is out producing revenue and really understanding how much this equipment generates to the operation's bottom line.

There are a couple of other considerations that come into play here, too. There is not a truck on the market — that snow contractors use — specifically designed for commercial snow plowing. From a slightly different viewpoint, trucks are not designed to be rammed into hard, packed piles of snow over and over and over again. Something eventually has to give. While plows themselves are constructed with failure points — so the stress is not directly transferred to the frame of the truck — the truck is not designed for the constant abuse aggressive plow drivers bless upon the steel construction of the truck itself.

Trucks are designed to carry "stuff. There's some sound logic to having a portion of your fleet dedicated to deicing. There's the obvious reduction in wear and tear on a vehicle dedicated solely to salt and deicing duties, which results in a longer overall life of a vehicle rock salt application rate can generate as much as three times what a plowing vehicle generates.

That simply makes absolutely no sense to me. A year ago, we held an open-forum discussion with those in attendance at Snow Magazine's Executive Summit. Two hours later, we concluded that event with a mandate from industry leaders to investigate an insurance solution for the professional snow industry, rock salt application rate.

So, with a group of industry volunteers — including Troy Clogg, Kyle Rose and John Allin, and many others who rock salt application rate their insight — we are happy to report that we have concluded our due diligence. And with that, Snow Magazine is excited to announce a partnership with Mills Insurance that will provide insurance for snow contractors.

Mills Insurance, who will administer the program, is an ideal partner for this endeavor. Their expertise in the snow industry gives them the necessary knowledge of today's insurance issues and how they impact snow contractors' business models. For the past six months, Mills Insurance, in partnership with Snow Magazine, has analyzed data, identified snow contractors' exposures and developed controls for those exposures, and is now ready to implement and monitor this process going forward.

Needless to say, this has been a daunting task; it will require on-going development to manage, monitor and adapt this program. When it comes to our industry and insurance, there are many complicated issues.

For insurance companies, it starts with slip-and-fall incidents. Those contractors who do not follow proper operational procedures, and have fair contract obligations in place, damage the industry.

By compromising on standards, snow contractors are making themselves uninsurable. Insurance carriers care about profitability.

If they are paying out more money in claims per year then taking in premiums, they are failing to make a profit for their shareholders. As a result, many insurance carriers have taken a very tough stance on snow operations because of sky-rocketing claims. To limit their exposure, insurance companies are eliminating this class of business or excluding the snow operations from contractors' primary businesses.

Many contractors are still not using proper contracts to limit their liability at the time of claim. In fact, contracts are heavily favored towards the property owner in taking all liability arising out of the work performed by the contractor.

For example, a pedestrian visiting a commercial building after a snow event trips and falls on the icy parking lot. They will sue the building owner and the building owner has contracted with a snow contractor who has taken on the liability.

Lastly, this country's laws do not favor snow contractors. The premises law rock salt application rate state by state and influences the level of involvement insurance companies have in this industry. There are states that are more understanding of the responsibility towards snow removal of property owners and there are states that are less tolerant. The insurance program we have developed with Mills Insurance takes into account all of these factors and more.

If we are going to drive down insurance claims, we will need to control the risk associated with our business. Many of you are already adopted these things, and should be commended for doing so. Others who are not need to integrate best practices into their businesses. These standards must reflect our industry's very best and encourage contractors to adhere to an accepted level of professionalism.

To be considered for this rock salt application rate, snow contracts will be required to verify they are practicing certain industry standards. Those industry standards include:. It's these important procedures that protect your business and the insurance company from lawsuits. In addition to operating the business by these industry standards, it is also important to the insurance company that contractors have a commitment to their business through education.

Therefore, to solidify this program, rock salt application rate it on a continual basis and safeguard the industry in the future, Snow Magazine is excited to announce the formation of the Accredited Snow Contractors Association ASCA. This means you have fulfilled the educational requirements, your business practices are in accordance with the industry standards listed above and your nominal dues are current. The ASCA will provide the proper education to the industry on an annual basis, represent snow contractors to the insurance industry and represent the industry on the local, state and federal level.

ASCA is setting aside 10 percent of all membership dues to be used in the hiring of lobbyists. There are two laws in this country that define liability for our industry. One is the "natural accumulation law" the other the "Connecticut rule. For those unfamiliar with these terms, "natural accumulation": state property owners and contractors are not responsible for natural accumulation of snow.

They are, however, responsible for unnatural accumulation. This means that as soon you move the snow, the property owner or you is responsible.
