Reducing Failure of Component Critical Parts
3 May 2023 2
Reducing failure of components which have installed critical parts is not ideal because an error can have significant consequences. Design manufactures need to give careful consideration in a number of areas to ensure such parts to not fail in operation.
The following slides will consider the following:

Quality Assurance – ensure that components are CE marked, of a high spec and failsafe
Burning in components – if components are burned in prior to placing into the system they are less likely to fail.
Planned replacement prior to burn out – have a programme in place so that if there are any signs of wear, SCCS components are replaced immediately.
Increase useful life – have a PMP in place of regular inspections to ensure all parts are working at optimum efficiency
Initial Design specification – were possible design machinery so that SCCS are not necessary and where needed use high spec durable materials fit for purpose.

Ensuring that you have machinery fit for purpose, monitoring its performance through reports, maintenance schedules, FMEA, use of other metrics can ensure the likelihood of failure is significantly reduced.
Having the capacity to switch to a secondly unit when faults or weaknesses are identified (like a secondary sever on a computer network) keeps the system moving whilst weaknesses if failed components can be identified through RCA, 5Whys, fishbone and other hazard analysis tools.

This presentation is a very basic outline. As a business you will need to determine the level of training required by staff to maintain a safe and protected business operations.
In no way does this presentation represent a suitable and sufficient training package for staff as every business has different needs thus no liability can be sought against the owner of this material.
Remember it is the business owners responsibility to have a suitable and sufficient business risk assessment in place, to keep it up to date and provide “competent” training for staff to fulfil their employed duties with regards machine safety
