Static electricity also can cause a shock
Static electricity can build up on the surface of an object and under the right conditions, can discharge to a person. This causes a shock
However, static electricity also can cause shocks or can just discharge to an object with much more serious consequences. For example, when friction causes a high level of static electricity to build up at a specific spot on an object, it can cause serious consequences. This can happen simply through handling plastic pipes and materials or during normal operation of rubberized drive or machine belts found in many worksites.
In these cases, for example, static electricity can potentially discharge when sufficient amounts of flammable or combustible substances are located nearby and cause an explosion. Grounding or other measures may be necessary to prevent this static electricity buildup and the results.
