Servicing operating theatre and surgical equipment
Overview
This standard identifies the competences you need to carry out servicing activities on operating theatre and surgical equipment, in accordance with approved procedures. You will be required to service a range of operating theatre and surgical equipment, such as insufflators, surgical diathermy devices, endoscopic equipment, camera systems, tourniquet devices, cryo-surgical devices, gas monitoring devices, pneumatic drilling/sawing devices, operating tables and surgical lighting equipment. This will involve dismantling, removing and replacing faulty items on a variety of different types of operating theatre and surgical equipment. You will be expected to apply a range of dismantling and reassembly methods and techniques, which are appropriate to the equipment being serviced and the type of components being removed/replaced, and which will include electrical, electronic and mechanical units and components.
Your responsibilities will require you to comply with organisational policy and procedures for the servicing activities undertaken, and to report any problems with the activities that you cannot personally resolve, or that are outside your permitted authority, to the relevant people. You must ensure that all tools, equipment and materials used in the servicing activities are removed from the work area on completion of the activities, and that all necessary job/task documentation is completed accurately and legibly. You will be expected to work with a minimum of supervision, taking personal responsibility for your own actions, and for the quality and accuracy of the work that you carry out.
Your underpinning knowledge will provide a good understanding of your work, and will provide an informed approach to applying the correct servicing procedures. You will understand the dismantling and reassembly methods and procedures used, and their application. You will know about the operating theatre and surgical equipment being worked on, and component properties, functions and associated defects, in adequate depth to provide a sound basis for carrying out the servicing activities, correcting faults and ensuring that the serviced equipment functions to the required specification and remains compliant with all standards and regulations.
You will understand the safety precautions required when carrying out the servicing 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.

- hazards associated with carrying out servicing activities on operating theatre equipment (such as exposure to live conductors, misuse of tools, anaesthetic gases) and how to minimise them and reduce any risks
- the basic principles of operation of the operating theatre and surgical equipment being serviced, and the function of individual components
- the human physiology directly associated with the operating theatre and surgical equipment being serviced
- the risks on the human body from external energy sources associated with operating theatre and surgical equipment
- the application and functions of a range of components used in the equipment (such as switches, sensors, overload protection devices, transformers, thermistors, rectifiers, printed circuit boards, valves, pumps)
- the care, handling and application of ohmmeters, multimeters and other electrical measuring instruments (such as dedicated test equipment, built-in test equipment)
- organisational policy on the repair/replacement of components, and the procedure for obtaining replacement parts, materials and other consumables necessary for the servicing activities
- how to check that the replacement components meet the required specification/operating conditions (such as values, tolerance, current carrying capacity, voltage rating, power rating, working temperature range)
- the techniques used to dismantle/reassemble operating theatre and surgical equipment (such as unplugging, de- soldering, removal of screwed, clamped and crimped connections, removal of pipes, hoses and mechanical components)
- methods of removing and replacing components without causing damage to the equipment or components
- the procedures and precautions to be adopted to eliminate/protect against electrostatic discharge (ESD) when working on sensitive equipment or devices
- the different types of cabling (such as multicore cables, single core cables, steel wire armoured (SWA), mineral insulated (MI), screened cables, data cables), and their application
- the use of relevant wiring and other regulations when replacing wires and cables
- methods of attaching identification markers/labels to removed components or cables to assist with re-assembly
