Vacuum Truck Safety Tips from Central Truck Sales of Miami
Industrial truck usage and performance depends greatly on the safety measures taken during operation. Central Truck Sales of Miami specializes in the quality service and sales of used trucks believes it is necessary to keep customers knowledgeable on the necessary safety aspects required for optimal operation. CTS will regularly publish articles that inform current and potential customers about the different safety and operational elements of each of the different types of used trucks for sale.
Vacuum trucks are carrier trucks with a heavy-duty industrial vacuum unit over its frame. They are primarily designed to vacuum liquid or particles from a site and then transport that to an appropriate disposal location. Towns and municipalities use Vacuum Trucks for street cleanup, sewers, contaminated soil cleanup, and other such duties. Vacuum trucks are the industry's janitors. Their jobs may seem to be simple, but if those jobs aren't done right, well, consider yourself left in a heap of…crap.
As we can all imagine, most vacuum truck operators do not have degrees in physics or chemistry. However, unless some fairly basic principles of physics are understood, vacuum trucks will not perform at peak efficiency and the operator may put himself in very real physical danger. Vacuum truck operators must understand some essential safety and operational techniques to keep themselves clear of potential physical danger.
First, diameter size of the vacuum hose is very important. Vacuum operators need to understand the importance of changing from one hose size to another and the impact of their decisions. Even the slightest change in diameter can make a HUGE difference. For instance, look at the difference between a ¼" hose and a 3/8" hose. One might think since the 3/8" hose is half as large as the ¼", and thus, would vacuum the contents at a 50% faster rate. As a matter of fact, contents are removed from the jar NINE TIMES FASTER! The jar with the larger hose is empty almost before the other has started. Its important to know that the hose diameter is paramount in getting the most out of your truck. A vacuum truck operator should NEVER change hose diameters in the middle of the job, as it is not only inefficient it can be seriously dangerous.
Second, vacuum truck performance decreases when friction is lost and smooth bore hoses almost always work better, especially for advanced drainage systems. An advanced drainage system hose is very rough inside, almost like a corrugated material. An operator can get by with a drainage system hose on a short job, but on a longer and tougher job a smooth bore hose is necessary.
When choosing a hose for a vacuum truck, safety is an issue as equal or more important than vacuum truck operation. With some vacuum truck jobs, an operator may be handling toxic chemicals. If the operator enters the tank to make a repair, fumes may become a hazardous safety risk. There is only one way in and one way out when dealing with a confined space. When operating a vacuum truck, never enter a tank when there are chemicals inside.
Another key safety point is that wet and dry material should never be mixed. In most cases, a vacuum truck operator will not know the chemical reaction if wet and dry materials are mixed. Again, more than likely they aren't chemists. With pressure being a key factor, it is vital for a vacuum truck operator to have a basic understanding of chemical reactions. Wet and dry combinations can prove extremely dangerous if the substances have adverse reactions when mixed. The only exception would be when neutralizing an acid might be necessary after a spill. A known chemical like bicarbonate of soda might be used with acid. In that case the operator has the knowledge to work safely.
Finally, a vacuum truck operator must always ground the truck. This is important for any product an operator uses, but especially for vacuum trucks. The hose may be sucking grain, dust, or something that might trigger a dust explosion. Also, an air mover should never be used on anything being removed with a temperature flash point of 140 degrees or less. That is an industry standard.
Vacuum trucks are very powerful machines and can give an operator a false sense of security. While vacuum trucks are so forgiving performance-wise, even when not used properly, ultimate performance still depends on how careful an operator is. Knowledge of vacuum truck safety and common safety measures will aid and optimize performance.
