Planned preventive maintenance

The standard refers to total planned preventive maintenance for which there is no definition in ISO/TS 16949. There is also a requirement for the system to include predictive maintenance. 

Predictive maintenance is part of planned preventive maintenance. In order to determine the frequency of checks you need to predict when failure may occur. Will failure occur at some future time, after a certain number of operating hours, when... 

Maintenance (description of planned preventive maintenance programmes and recording system). 

Normal operation—The computer system is maintained in accordance with the planned preventative maintenance schedule. Typical activities include recalibrating field instrumentation and computer I/O cards in accordance with site calibration procedures, running system diagnostics, checking operator logs for any abnormalities, and planning service visits by the system supplier. 

There should be a planned preventive maintenance programme, procedures and records for the HVAC system. Records should be kept. 

SOP and record planned preventive maintenance of specific equipment SOP training (plus record of personnel)... 

A Planned Preventative Maintenance Programme and Standard Operating Procedure for carrying out the maintenance, should be in place. It should refer to all relevant equipment and apparatus to be included in the programme. Responsible persons, should be fisted, canrying out maintenance in accordance with the specified time schedule. Records should be kept as evidence of maintenance checks and repairs. 

Handling aids and equipment - can you provide equipment that is suitable for the task carry out planned preventative maintenance to prevent problems ... 

As part of a planned, preventative maintenance (PPM) schedule, pump oil should be drained and sterilised before discarding together with decontaminated filters, used gaskets, seals and components which have been changed during maintenance. After the PPM schedule, the freeze-drier should be validated to confirm the correct functioning of the drier and components including specialist items added to ensure safe operation. 

A programme to prevent business interruption can include planned lubrication, planned preventive maintenance, condition monitoring, statutory inspections, machinery replacement programmes, availability of key spares, identification of key machines, processes, areas, personnel etc. within the organisation, continued supply of raw materials, minimisation of production bottlenecks, and highlighting dependencies on specific items of plant, suppliers, customers, personnel, and/or public utilities (e.g. gas, electricity). 

The guide emphasizes the need to set up an effective system of maintenance for PPE. This should be proportionate to the risks and appropriate to the particular PPE. It could include, where appropriate, cleaning, disinfection, examination, replacement, repair and testing. For example, mechanical fall arrestor equipment or sub-aqua breathing apparatus will require planned preventative maintenance with examination, testing and overhaul. Records should be kept of the maintenance work. Gloves may only require periodic inspection by the user as necessary, depending on their use. 

In many cases this will require routine and planned preventive maintenance of work equipment. When checks are made priority must be given to ... 

E-10 Maintenance of Medical Gas and Vacuum Systems in Health-Care Facilities. Contains guidance for the health-care community in developing a planned, preventative maintenance program for centrally piped medical gas and vacuum systems in health-care facilities and hospitals. The requirements given are applicable to most installations. This document does not apply to the construction or repair of any component of a medical gas system (14 pages). 

Planned preventative maintenance - is the term given to the technique of maintaining equipment before it needs maintenance rather than reacting to equipment failure. 

Plan preventive maintenance, and schedule regular repairs on all handling equipment. 

A planned preventive maintenance system for the fixed installation should be drawn up and should include frequent visual inspections and combined inspections and tests (lEE Guidance Note No. 3 recommends a maximum of three months between the inspections and between combined inspections and tests). The aim is to detect damage and defects which may create danger and which should be repaired immediately. If repairs have to be deferred, the defective apparatus should not continue in use but should be disconnected from the system until it has been made good. 

The inspection dates should be entered in a diary or call-forward system or planned preventive maintenance software package which is consulted by the supervisor when planning the work schedule. 

Abnormal occupancy levels - failure or planned preventive maintenance of fire safety critical systems... 

All work equipment must also be adequately and suitably maintained in an efficient state to prevent breakdown and/or risks of fire, health or safety. A programme of planned preventive maintenance (PPM) must be implemented to ensure that work equipment is kept in efficient working order and in good repair and the fire risks are reduced to a reasonable level. The frequency of maintenance should be determined by ... 

In relation to fire safety it is particularly important to ensure that moving parts of machinery are subject to planned preventive maintenance to prevent the equipment being a source of ignition. 

In all cases the inspection and testing must be carried out by suitably qualified and competent staff. It is therefore important that prior to providing any piece of work equipment an employer or responsible person must consider, plan and take account of the detailed arrangements for the safety inspection and planned preventive maintenance of any such equipment. 

These are arrangements that ensure that risk controls (workplace precautions) are implemented and maintained. For example the provision for ensuring that an adequate level of supervision is maintained during work processes a system for planned preventive maintenance for work equipment and specific safety systems and establishing a programme of inspections and audits for buildings, sites and workplaces. 

Ensuring that any electrical equipment is subject to regular maintenance (planned preventive maintenance) must also be seen as a key area to prevent ignition sources initiating an explosion. 

Fires caused by heaters and heating systems can be divided into two key areas those that are caused by faulty systems including poor design, inappropriate installation or lack of planned preventive maintenance and those that are caused by inappropriate use or misuse. 

The preceding paragraphs detail the hazards associated with electrical and gas systems which are also common to those sources of energy used by heaters and heating systems. As has already been discussed, the poor design, inappropriate installation and lack of planned preventive maintenance are all causes of fire. It is therefore appropriate to ensure that systems are designed, installed and subject to planned preventive maintenance. 

The installation of any heaters and heating systems must be undertaken by competent engineers installing to the design specification. It is also likely that these engineers will be retained to undertake the planned preventive maintenance of the system to ensure that it remains safe and fit for its intended purpose. 

If a waste compactor is used ensure that the safe system of work includes turning off when the building is not occupied and the unit is subject to a planned preventive maintenance regime... 

Any intrinsically safe equipment will also need to be used by competent persons and included both within an inspection and testing programme undertaken by competent engineers and in a planned preventive maintenance programme. 

A system for inspecting workplace precautions is essential in any proactive monitoring programme. On many occasions it can form part of an organisation s arrangements for the planned preventive maintenance of plant (e.g. electrical maintenance and testing) and equipment (e.g. flashback arresters for oxy/fuel systems) which are also covered by legal requirements.
