Maintain fluid power equipment within an engineered system used in food and drink operations
Overview
This standard identifies the competences you need to carry out corrective maintenance activities on fluid power equipment within an engineered system used in food and drink operations, in accordance with approved procedures. You will be able to maintain a range of equipment, such as pumps, valves, actuators, sensors, compressors and other fluid power equipment, which are working in an integrated system on mobile or static plant involving interactive technologies: mechanical, electrical, or process controller. Food and drink operations is a term used in this standard to cover the following sub sectors of Meat, Drinks, Confectionery, Fresh Produce, Bakery, Seafood and Dairy.
You will be able to isolate and disconnect items and components of the interactive technologies in order to gain access to and remove the fluid power units and components that require replacing or repair. This will involve dismantling and reassembling a variety of different types of assemblies and sub-assemblies which, in some instances, will need to be dismantled to component level.
You will be able to work with minimal supervision, taking personal responsibility for your own actions, and for the quality and accuracy of the work that you carry out.
Note: Fluid power is a term describing hydraulics, pneumatics and vacuum technologies
Performance criteria
You must be able to:
- work safely at all times, complying with health and safety, environmental and other relevant food and drink regulations, directives and guidelines
- plan and communicate the maintenance activities to cause minimal disruption to normal working
- obtain and use the correct issue of company and/or manufacturers' drawings and maintenance documentation
- select equipment and materials for maintenance activities
- isolate fluid power systems in accordance with organisational procedures
- release stored energy in accordance with organisational procedures
- provide and maintain safe access and working arrangements for the maintenance area
- carry out the maintenance activities using appropriate techniques and in accordance with organisational procedures
- follow the relevant maintenance schedules to carry out the required work
- reconnect and return the system to service on completion of the maintenance activities
- report any instances where the maintenance activities cannot be fully met or where there are identified defects outside the planned schedule
- complete maintenance records and documentation in accordance with organisational procedures
- dispose of waste materials in accordance with safe working practices and approved procedures
Knowledge and Understanding
You need to know and understand:
- the health and safety and environmental requirements of the area in which the maintenance activity is to take place, and the responsibility these requirements place on you not to compromise food safety
- the isolation and lock-off procedure or permit-to-work procedure that applies to the system being worked on, including critical control points
- the specific health and safety food and drink precautions to be taken during the maintenance activities, and their effects on others
- the requirements of the British Retail Consortium (BRC) guidelines and standards in relationship to the maintenance activities
- the specific requirements of your customer/client specifications in relationship to the maintenance activities
- your responsibilities in relationship to Hazard Analysis and Critical Control Points (HACCP), Threat Assessment and Critical Control Points (TACCP), Vulnerability Assessment and Critical Control Points (VACCP) during the maintenance activities
- what constitutes a hazardous voltage and how to recognise victims of electric shock
- how to reduce the risks of a phase to earth shock (including insulated tools, rubber mating and isolating transformers)
- the importance of wearing protective clothing and other appropriate safety equipment (PPE) during the maintenance activities, and where to obtain it
- hazards associated with carrying out maintenance activities on an integrated system (including handling fluids, stored pressure/force/temperature, electrical supplies, process controller interface, using damaged or badly maintained tools and equipment, not following laid- down maintenance procedures), and how to minimise these and reduce any risks
- regulations and codes of practice that apply to working with fluid power equipment
- how to obtain and interpret drawings, charts, circuit and physical layouts, specifications, manufacturers' manuals, history/maintenance reports, symbols used in fluid power, and other documents needed for the maintenance activities
- the basic principles of how the system functions, its operation sequence, the working purpose of individual units/components, and how they interact
- the principles of the equipment's design features for safe operation in a food or drink environment such as minimising the chance of contaminates or foreign bodies in the final product
- the importance of following the correct de-contamination procedures when pipelines and systems are broken into as part of the maintenance
- principles and theories associated with fluid power equipment (including cascading and truth tables, logic/ladder diagrams)
- how to construct and apply ladder logic, sequential charts/tables or functional diagrams
- dry and lubricated systems and their application
- selection, types and characteristics of fluids for the system
- the effects of pressure and flow on the performance of the system
- the identification of different compressors (including screw piston, rotary vane)
- the identification of different hydraulic motors (including piston, gear, vane)
- the effects, and likely symptoms, of contamination in the fluid power system
- the different types of pipework, fittings and manifolds, and their application
- the identification, application, function and operation of different types of valves (including poppet, spool, piston, disc and slide)
- the identification, application function and operation of different types of sensors and actuators (including rotary, linear, mechanical, electrical)
- the identification, application function and operation of different types of actuators/cylinders (including single acting, double acting and telescopic)
- the identification and application of different types of pumps (positive, gear vane and piston), as applicable
- the application and fitting of static and dynamic seals
- company policy on repair/replacement of components, and the procedure for obtaining replacement parts, materials and other consumables necessary for the maintenance activities, including safe storage
- the sequence to be adopted for the dismantling and reassembling of the equipment, to both sub-assembly and individual component level
- the techniques used to dismantle/re-assemble integrated equipment (release of pressures/force, proofmarking to aid assembly, plugging exposed pipe/component openings, dealing with soldered joints, screwed, clamped and crimped connections)
- methods of attaching identification marks/labels to removed components or cables, to assist with re-assembly
- methods of checking that components are fit for purpose, and the need to replace `lifed' or consumable items (including lubricants, seals, gaskets, filters, pistons, spools and bearings)
- how to make adjustments to components/assemblies, to ensure they function correctly
- how to check tools and equipment are free from damage or defects, are in a safe and usable condition, and are configured correctly for the intended purpose
- the processes in place to segregate the tools and equipment used into high or low risk areas
- the checks required to ensure that all tools, materials and components are all accountable before operating the equipment
- the importance of making `off-load' checks before applying full pressure
- the cleaning requirements/policies in place before returning the equipment into full operational production
- the generation of maintenance documentation and/or reports on completion of the maintenance activity
- the manufacturer's equipment operating and control procedures to be applied during the maintenance activity
