Vac_Truck_for_SaleWhen looking for a vac truck for sale, certain precautions should be taken before the purchase. The vehicle should be thoroughly inspected to make sure all components, particularly the tank and pump, are in good working condition. It may also be useful to talk to the seller to find out how long and for what purpose the vacuum truck was previously used as well as what type of materials may have been stored in the tank.

Worker Protection

Machine guards should cover any moving parts to prevent worker’s limbs from becoming trapped and injured. One means of defense against this are safety releases that help protect truck operators. There are typically three such releases on a vacuum truck:

  • Remote – The remote release can be operated from a distance.
  • Manual – The manual release is located near the truck itself
  • ‘T’ – The inline “T” release is placed inside the actual hose and acts as an emergency shut-off mechanism.


The hose diameter is of great importance and can cause many problems if an operator is unaware of the physics involved in suctioning. A hose with a variable diameter can become easily clogged if the nozzle is smaller than the opposite end. This is caused by the reduced air speed that travels through the hose. Similarly, very long hoses will also reduce air speed as the material travels through the hose and may also cause clogging.

Safety Procedures

After purchasing a vac truck for sale, safety must always be observed during vehicle operations by observing the follow procedures:

  • Thorough Cleaning – Used vacuum trucks may contain some residue of toxic waste which could be harmful to when inspecting the tank and could produce dangerous fumes. Thorough cleaning is necessary immediately after purchase and as well as at regular intervals during future operations.
  • Safety Masks – It is also important for all drivers and operators to wear protective facial masks during vehicle operations. Since the vacuum tank is a confined space, it should never be entered if there are chemicals or any chemical residue inside.
  • Monitor Pressure – Tank pressure levels should be monitored at all times; all dimensions of the vehicle should be inspected regularly to monitor any indications that the tank may be leaking.
  • Never Work Alone Vacuum trucks should never be operated alone. Even a seasoned driver who is aware of most potential hazards could suffer an accident or experience fatigue.

Hazard Avoidance

It is important the materials being suctioned are closely watched. Mixing of wet and dry compounds should be avoided, as it could cause violent chemical reactions. Additionally, the vehicle should be properly grounded to avoid hazards associated with static electricity. Grain dust, when exposed to electrical currents, can contribute to a dust explosion. Industry standards dictate that no material with a temperature flash point lower than one-hundred forty degrees should be subjected to these air movers.

As with any heavy machinery, any vac truck for sale should include the manufacturer’s user manual and safety instructions. Though general safety measures are applicable to most vacuum trucks, individual models have variations that must be observed. It is imperative to read such instructions carefully before first time operations as well as re-read them regularly to keep the procedures always at the forefront of safety thoughts at all times. This is the only way to ensure complete protection from harm while operating such a powerful vehicle!
