Reactive maintenance is done after equipment has stopped working correctly. It is often contrasted with preventative maintenance, which is done according to a set schedule.
While reactive maintenance may seem somewhat negligent, it is common for some equipment. If a piece of equipment has a low risk of failure and the cost of failure is not too high, experts may recommend relying solely on reactive maintenance. For certain items, however, this may not be an option.
A combination of preventative and reactive maintenance is popular for a wide range of items. Cars, for example, need preventative maintenance at regular intervals. Oil changes are common, and most cars need to have their timing belts changed after approximately 75,000 miles. However, car owners tend to spend more money on reactive maintenance. When a component of a car causes problems, owners typically take it in to have the faulty part replaced, which is a form of reactive maintenance.
Airplanes receive a considerable amount of preventative maintenance. Since problems that occur during flight are likely impossible to solve, companies invest a significant amount of money ensuring that routine inspections uncover them. However, reactive maintenance is more common than many realize. Avionics equipment, in particular, malfunctions regularly.Learn More
The most reactive metal in the periodic table is francium. Francium belongs to the alkali metals, a group on the periodic table whose members are all highly reactive. These metals are highly reactive because they all have only one valence electron.Full Answer >
Fluorine is the most reactive of the halogens because it is at the top of the halogen group, which is the second to right group on the periodic table. With halogens, the higher an element is in the column, the more reactive it is.Full Answer >
A metal atom's aptitude to lose electrons to other atoms causes it to be more reactive. Involved in the scientifically determined aptitude is the speed at which a metal atom can lose electrons, as well as the substances with which the atom is likely to react.Full Answer >
The most reactive metals react with water to form hydrogen gas and their oxides or hydroxides, and with acids to form their oxides or hydroxides. According to the activity series, the first nine metals are highly reactive with water and the next six with acids.Full Answer >
