Do you use preventive maintenance management measures to schedule periodic inspection and maintenance activities ... 

Most emphasis is placed on a program of rigorous preventive maintenance. Appropriate climate conditions can help to prevent mold attack, which typically only occurs at elevated relative humidity. Storage furniture which provides an effective barrier for insects, regular inspection of the collections, monitoring of all collection areas with insect traps, and access control measures which minimize the chance of insect entry into the collection areas, are some aspects of an effective pest control management program (175). 

A PPM program is needed to avoid equipment failures, utiHty outages, and production intermptions. From a cost savings angle it is extremely important to do preventive maintenance in order to avoid breakdowns. Periodic inspections and a good lubrication program uncover conditions that could lead to breakdowns. When problems are found eady, they can be taken care of without work intermption and costly repairs. Sometimes faciHty managers are so afraid of downtime that preventive maintenance is done too often. In other cases production does not allow adequate time to provide proper maintenance. 

Compliance. Compare achievement in specific PSM elements against previous audit findings for the site. This helps indicate the effectiveness of the management system. For example, if previous audits found that preventive maintenance was not kept up to date on pressure relief systems, has the system weakness (or absence) that allowed this to occur been corrected ... 

As with previous, similar exercises, encourage your team to be creative. Like any sound management system, your PSM system probably creates unexpected side benefits over and above those related spedfically to safety performance. For example, the pilot test may have demonstrated that a new system, once installed, enabled the facility to reduce unplanned downtime with better planning and use of preventive maintenance. Or perhaps the pilot test process itself may have helped improve relations between the facility and corporate staff. 

The change management process should also ensure that a root cause analysis has been conducted to make sure the real problem has been identified and corrected. For example, if a pump seal fails it could simply be replaced with an identical seal. However, it may have failed because it was left in service beyond its natural life and the real failure was in the preventative maintenance program that should have replaced it earlier. 

The plant engineer and his maintenance manager will establish whoever carries out the work, basic strategy, programming and procedures. Inspection checklists and record sheets are necessary for systematic location of critical elements/potential defects and setting out frequencies of inspection. Computers and work processors are an obvious aid to effective maintenance management. Inspection-based preventive methods are demonstrably cost effective. 

Troubleshooting deals with identifying and solving problems. Problems can be immediate or long term and can be associated with off-spec products, poor efficiency, process improvements, capacity increases, or potential shutdown items. Problems can be related to management, operation, hardware and equipment, or process issues. Solutions can include improved operating procedures and training, preventative maintenance, or installation of new equipment or controls. 

Preventive maintenance programs must be organized, managed, and fully supported by management. Good results may not be immediately apparent, but bad results are apparent when plants are not appropriately maintained. 

Identified hazards can either be reduced at the root (e.g., reduction of inventory) or by introduction of protective systems (e.g., automatic emergency shutdown). The increased understanding of the chemistry and the process that is obtained from hazard evaluation procedures provides guidance for many other elements of process safety management as well (e.g., procedural instructions, emergency strategies, personnel training, and preventive maintenance).

Problem is being managed through an aggressive preventive maintenance program. 

Evaporative TIC technologies have the minimum installed and operating costs. The operating electric parasitic load is generally considered insignificant. Water chemistry management is crucial to prevent maintenance problems caused by dissolved or suspended matter in the water, fouling either the evaporation media or the turbines themselves.

All cooling water treatments produce the best results in clean well-maintained cooling systems. (It is easier to keep a clean system clean than to prevent a dirty system from getting dirtier.) Therefore, it is in the field representative s best interests to ensure that a suitable program for maintenance management and good housekeeping practice is implemented. These activities should also be planned and documented, similar to all water treatment activities. 

Maintenance management activities ensure cooling system functional performance and will cover operational maintenance, corrective or emergency maintenance, and routine preventative maintenance. 

Ongoing monitoring, change management, calibration, and preventive maintenance are essential components of validation maintenance.
