Using a crash truck is an effective way to reduce the risk of someone being seriously hurt or even killed on a highway construction site. In doing so, you can trust that the material inside of the truck's accident attenuation barrels will dissipate energy and prevent a speeding vehicle from plowing into the construction workers who are working at the other end of the truck. Generally, these barrels will be filled with either water or sand, both of which are effective at dissipating energy. Here are some pros and cons of using water.
Pro: It's Readily Available
A major benefit of using water for your accident attenuation barrels is that it's readily available. You can fill your barrels up anywhere that you have access to water, from a garden hose to a water truck on the job site. The level of convenience isn't the same when you choose sand. While sand is available from many vendors, it's not as widely available as water. And, when you need to fill the barrels, you need this process to be convenient.
Con: It Will Harden In Cold Weather
Your geographical location should influence your choice of what material you put in your accident attenuation barrels. Water is ideal during the summer months, but if you're using a crash truck during the winter and the temperature is consistently below freezing, water won't be a good choice. It will freeze, which means that each barrel will become a hard object that won't dissipate energy effectively. In a cold climate, sand is a better choice.
Pro: It Cleans Up Easily
In the event of an accident between a speeding vehicle and your crash truck, the contents of your barrels will be spilled all over the road. When your barrels are filled with water, it's not a big deal. While the road will be wet for a period of time, it will quickly dry, just as it does after a rainfall. Conversely, several cubic feet of sand strewn across the road results in a significant cleanup project.
Con: It May Freeze On The Road
Perhaps the temperature is slightly above freezing, so you've decided to keep water in your barrels instead of switching to sand for the cooler temperatures. Should a vehicle hit the crash truck and rupture the barrels, leading to a thin layer of water over the road, this could be a hazard. In the event of a rapid freeze before the water evaporates, your scene could be slippery for approaching vehicles. Fortunately, you always have a choice of water or sand, so you can make an informed decision based on the above criteria.
