There are three factors that must come together for a hose whipping hazard to exist:
1. There must be air in the delivery system,
2. There must be something pushing on the air, and
3. There must be a restriction near the hose end causing the air to compress.
Hose whipping accidents can be avoided if the proper precautions are taken when air has been taken into the delivery system. Each person involved has to know what to do. Everyone needs specific knowledge, and has to heed the warnings to protect themselves. Communication is crucial. To see an example of how dangerous hose whipping is, watch the short video clip on the American Concrete Pumping Association website.
