The Release Of Energy

The Release Of Energy

Oct 27, 2020

The release of energy (or energy) and how to understand, such as hydraulic oil pipe, the normal work when there is pressure in the pipeline, from the perspective of energy can say there is potential energy, if you need to open it when maintenance hydraulic pipe for repair, if maintenance personnel did not correctly will the pressure inside the pipeline uninstalled, so when maintenance personnel to open pipe joints, pipe oil spurts out, may hurt and maintenance personnel. The energy analysis is the release of potential energy.

Before implementing Lock Out Tag Out, it is important to identify the energy hazards associated with the operation. Sometimes this is not easy. Harmful energy includes: electric energy, mechanical energy, thermal energy, potential energy, chemical energy, radiant energy and so on. The operator needs to be aware of what energy hazards the operation is exposing him to. For the production personnel, it will be easier to judge the implementation of cleaning operation, while for some maintenance personnel, the maintenance operation will be more complicated. For example, if as a maintenance worker, the discharge pump of the chemical storage tank below needs to be replaced, what energy hazards do you think are involved?

One is mechanical energy. If the pump is suddenly started when the pump is removed, the maintenance personnel may be injured if they come into contact with the operating belt or gear. The other one is the chemical in the pipe, which may have pressure, which is potential energy; And if the chemical itself is hazardous, there may be chemical energy;

So some companies have energy sequestration plans when LOTO more complex devices. The companies that do a good job will create an EIP-energy isolation plan for all of their facilities. Some companies are called LOTO Procedure. It is convenient for employees to identify hazardous energy and locate corresponding isolation points of hazardous energy. It takes a lot of time and effort to make this thing, and the maintenance personnel cannot rely on this EIP completely. The maintenance personnel need to make more specific judgments about the operation being repaired.
