    Operator's responsibility- trend, maintenance & emergencies


    Trend could be detected by looking at the chart, but not all trends can be detected in this way. There are some trends that operators can detect only by making periodic inspections of process system.

    For example, during routine inspections, an operator may find that an unusual sound from a pump is getting louder or that the temperature of a pump bearing is increasing. Both of these symptoms are sings of trend.

    To be able to detect changes during routine equipment inspections, operators need to know each piece of equipment normally looks, sound, and feels, operators must also know what the values of process variables' should be under various operating condition.

    The basic process of analyzing a trend can be broken down into the following steps.
    • Determining the meaning of the trend
    • Determining the cause of the trend
    • Determining what actions or adjustment are needed to correct the trend
    • Determining the impact that the adjustments will haven on the rest of the system

    Part of an operator's job is detecting trends and analyzing them to determine what, if any, corrective action is needed.

    In many facilities, operators perform minor maintenance on system equipment. In addition, operators normally assist the maintenance department by taking precautions to protect personnel and equipment while repairs are being performed.

    To prepare for maintenance work, operator may have to de-energize electrical systems, depressurize pressurized systems, and drain fluid systems. Also, during maintenance operator must be taken another precaution that is lock tagout to preventing a switch or a valve from being used.

    In order to be prepared for an emergency, operators must be familiar with the facility's emergency operating procedures. Emergency operating procedures are special sets of instructions that list the actions operators must take to deal with problems that could cause equipment damage or personal injures.
    Operators should be familiar with:
    • Materials in their facility
    • Hazards that they can present
    • And know how to put on and use the facility's PPE.
