IES provides a complete end-to-end service: from initial design through to site installation and aftercare. Every job is assigned a project manager, a fully trained engineer who acts as a single point of contact and all critical processes are carried out on site allowing a seamless, rapid service.

Safety in Design
Our safe design approach begins in the conceptual and planning stages. By analysing and assessing potential faults and proposing safety requirements up-front we ensure the safety of the finished product in each of the lifecycle phases.

Safety in Design

Our highly qualified and experienced engineers are trained in the development of safe designs that comply with the EU Machinery Directive 2006/42/EC and EN ISO13849-1. The use of the Applied Chart Risk Graph to calculate the Performance Level (PL) is also widely adopted in our methodology.

A calculation of the PL is applied to each part of the control system – and combination of them – which performs a safety function using the following values:

• MTTFd (Mean Time To Failure dangerous)
• DC (Diagnostic Coverage)
• CCF (Common Cause Failure)
• Structure (Category)
• Behaviour of the safety function at error conditions
• Safety related software
• Systematic errors
• The ability to execute a safety function under foreseeable conditions

Once the required performance level has been established – and as well as utilising more traditional methods – we explore other higher-level systems which utilise the latest technology and can often prove to be a much safer and more cost-effective solution in the long term.
