Carrying out fault location activities on assistive technology systems and equipment
Overview
This standard identifies the competences you need to locate faults on assistive technology systems and equipment, in accordance with approved procedures. You will be required to locate faults on equipment such as manual and powered wheelchairs, buggies and scooters, postural support systems, hoists, personal communication aids, walking aids, adjustable beds, pressure relief and distribution equipment, telecare alarm systems, aids for daily living, environmental control systems, associated battery charging systems for assistive technology systems and equipment.
You will be expected to use a variety of fault location methods and procedures, such as gathering information from the person who reported the fault, using recognised fault finding techniques and diagnostic aids, measuring, inspecting and operating the equipment.
Your responsibilities will require you to comply with organisational policy and procedures for the fault location activities undertaken, and to report any problems with these activities, or with the tools and equipment used, that you cannot personally resolve or that are outside your permitted authority, to the relevant people (such as the reporting of any actual or potential safety related problems to the appropriate regulatory body). You will be expected to work to instructions, either alone or in conjunction with others, taking full responsibility for your own actions, and for the quality and accuracy of the work that you carry out.
Your underpinning knowledge will be sufficient to provide a sound basis for your work, and will provide an informed approach to applying fault location procedures to assistive technology systems and equipment. You will have an understanding of the basic fault location methods and techniques used, and their application. You will also know how to interpret information obtained from fault finding aids and equipment, in adequate depth to provide a sound basis for carrying out the activities.
You will understand the safety precautions required when carrying out the fault location activities, especially those for isolating the equipment. You will also understand your responsibilities for safety, and the importance of taking the necessary safeguards to protect yourself and others in the workplace.
Performance criteria
You must be able to:
P1 work safely at all times, complying with health and safety and other relevant regulations, directives and guidelines
P2 review and use all relevant information on the symptoms and issues associated with the product or asset
P3 investigate and establish the most likely causes of the fault or faults
P4 select, use and apply diagnostic techniques, tools and aids to locate faults
P5 complete the fault diagnosis within the agreed time and inform the appropriate people when this cannot be achieved
P6 determine the implications of the fault or faults for other work and for safety considerations
P7 use the evidence gained to draw valid conclusions about the nature and probable cause of the fault or faults
P8 complete and store all relevant documentation in accordance with organisational requirements
Knowledge and Understanding
You need to know and understand:
K1 how to work safely at all times, complying with health and safety and other relevant regulations, directives and guidelines
K2 the statutory and advisory documentation relating to medical devices
K3 the appropriate working practices, and the need to respect the patient and carer in the patient environment, at home or in the community (where appropriate)
K4 the importance of reporting any `adverse incidents' with the equipment to the regulatory authority
K5 the importance of wearing the appropriate personal protective equipment (PPE), and of keeping the work area clean and tidy
K6 the procedure to be adopted to establish the background of the fault(s)
K7 how to use the various diagnostic aids to help identify the location of the fault(s)
K8 the various fault location techniques that can be used, and how they are applied
K9 how to evaluate sensory information
K10 how to assess evidence and evaluate the possible causes of faults/issues
K11 how to use a range of fault diagnostic equipment to investigate the problem(s)
K12 the importance of carrying out electrical safety tests on medical equipment, and the implications if this is not carried out (where appropriate)
K13 the care, handling and application of mechanical measuring/test equipment
K14 how to check that measuring/test equipment is within calibration, and that it is free from damage and defects
K15 how to obtain and interpret information from job instructions and other documents needed in the fault location process
K16 the basic principles of how the assistive technology system and equipment functions, its operating sequence, the purpose of individual units/components and how they interact
K17 the issues that can occur during the fault location activity, and how they can be minimised
K18 how to evaluate the likely risk to yourself and others, and the effects the fault(s) could have on the overall process or system
K19 the importance of completing the correct documentation following the fault location activity
K20 the extent of your own responsibility and to whom you should report if you have problems that you cannot resolve
Scope/range
Scope Performance
1 Carry out all of the following during the fault locating activity:
1.1 plan the fault location methods and procedures in conjunction with others
1.2 use the correct issue of maintenance documentation (such as drawings, manuals, maintenance records)
1.3 adhere to procedures or systems in place for risk assessment, personal protective equipment and other relevant safety regulations and procedures to realise a safe system of work
1.4 ensure the safe isolation of equipment (such as mechanical, electrical, gas, air or fluids)
1.5 ensure that safe access and working arrangements have been provided for in the area where the fault finding is taking place
1.6 carry out the fault location activities, using approved procedures
1.7 identify the fault(s), and consider appropriate corrective action
1.8 in conjunction with others, take actions to resolve the problem(s)
1.9 dispose of waste items in a safe and environmentally acceptable manner
