What is Rope Access?

Our Rope Access personnel are all IRATA certified. The IRATA system is a safe method of working at height utilising ropes and related equipment to gain access to and from the location of work and to be supported there.

The main benefit of employing rope access techniques is the safety and swiftness with which technicians can move to or from awkward or difficult locations in order to complete tasks with minimal disruption to other work.

The main objective when using rope access methods is to carry out the work professionally, with minimal accidents, incidents or dangerous occurrences. In order to ensure a safe system of work is maintained at all times, whilst avoiding damage to property or harm to the environment, careful planning and documented risk assessments are undertaken for each operation.

We follow the IRATA International Code of Practice (ICoP) which gives recommendations and guidance on the use of rope access methods in order to provide a safe system of work.

MPI

Magnetic particle inspection (MPI) is a non-destructive testing (NDT) method of detecting surface and slightly subsurface discrepancies in ferromagnetic materials. The process uses a magnetic field. The material to be tested can be magnetized by direct or indirect magnetization. Direct magnetization occurs when the electric current is passed through the test object and a magnetic field is formed in the material. Indirect magnetization occurs when no electric current is passed through the test object, but a magnetic field is applied from an outside source. The magnetic lines of force are perpendicular to the direction of the electric current which may be either alternating current (AC) or some form of direct current (DC) (rectified AC).

The presence of a surface or subsurface discontinuity in the material allows the magnetic flux to leak. Ferrous iron particles are applied. If an area of flux leakage is present the particles will be attracted to this area. The particles will build up at the area of leakage and form what is known as an indication. The indication can then be evaluated to determine what it is, what may have caused it and what action should be taken, if any.
