Maintenance work orders

Shutdown work request log When the planning department receives a shutdown work order, it is immediately recorded in the shutdown work request log. The maintenance clerk should verify that the item number assigned agrees with the next sequential number on the maintenance work order log. Work requests forwarded to shutdown planning should indicate equipment number and...

If the repair is successful, no further work is necessary. If unsuccessful, a maintenance work order is written for craftsmen to make a second repair attempt within a prescheduled time, usually 15 days. If the second repair is successful, no further work is necessary. If the component cannot be repaired while the equip-...

Finally Fig. 5 represents an UML State Diagram detailing the transitions or changes of state that an object (in this case a Maintenance Work Order) can go through in the system. This kind of diagrams shows how an object moves from one state to another and the rules that govern that change.

Clinical engineering defines the time intervals based on manufacturer s recommendations, risk levels, and current hospital experience. Clinical engineering uses the AIMS database to define and maintain the preventive maintenance and inspection intervals on appropriate equipment in the inventory, automatically generating interval-based inspection and preventive maintenance work orders monthly. 

An effective preventive maintenance system can ensure that equipment and machinery operates properly, which reduces the chance of an accident. A quick-response corrective maintenance program is also very important. Faulty equipment and machinery that could cause a serious injury or fatality should be taken immediately out of service. Maintenance work orders that correct hazards should be identified as unique from other work orders. You don t want safety work orders at the bottom of a stack of work orders. 

Think about each maintenance work order. Does it need a PSSR What about operations changes Do they need a PSSR Remember that there is no need to wait for a scheduled audit to evaluate your system. Each use of an element of PSM is an opportunity for improvement. 

Work-order types policy. This is used to define categories of maintenance work orders. Examples include preventive maintenance, predictive maintenance, projects, and call center. 

Maintenance work orders will be analyzed for valid safety priority for correction. 

The isomerization unit Splitter Tower high-level alarm had been reported as not functioning several times in the 2 years prior to accident - but maintenance work orders were closed without repairs being carried out. 

A formal record is desirable for every inspection and preventive maintenance job. If the work is at all detailed, a checklist should be used. The completed checklist should be returned to the maintenance office on completion of the work. Any open preventive maintenance work orders should be kept on report until the supervisor has checked the results for quality assurance and signed off approval. Modem computer technology with handheld computers and pen-based electronic assistants permits paperless checklists and verification. In many situations, a paper work order form is still the most practical media for the field technician. The collected data should then be entered into a computer system for tracking. 

Inspect a chain for wear by inspecting the links for worn bushings. If worn bushings are noted, write a corrective maintenance work order so that the replacement can be planned and scheduled at a later time. 

Inspect sprockets for worn teeth and abnormal wear on the sides of the sprockets. (The question is Can the sprockets and chain last for two more weeks without equipment stoppage ) If the sprockets and chain can last two weeks then write a corrective maintenance work order in order for this job to be planned and scheduled with the correct parts. If the sprocket cannot last two weeks, then change all sprockets and the chain. Set and check sheave and chain alignment and tension. WARNING When... 

Identify any type of oil, grease, or chemical within 36 inches of belts (oil leakage from gearbox, motor, bearing, or chemicals from other sources). Write a corrective maintenance work order to repair leak or eliminate source of oil, grease, or chemical from the area. 

Check sheaves for wear. Use a sheave gauge to ensure the sheave is not worn. If worn, write a corrective maintenance work order to change the sheave at a later date. 

Employees should use this system only if a special high priority code for maintenance work orders involving safety and health hazards and violations exist This will enable the maintenance supervisor to give these types of woik orders higher priority than normal maintenance. Copies of these high-priority orders should also be delivered to the safety department so that ensuing corrective action can be tracked.
