Assessment of a design prepared for a device to check whether a designer has adequately addressed all safety issues that may affect the safety of a device throughout its life.
Typical areas of inspection include:
- the design risk assessment;
- the design calculations;
- the design documents, which should be consistent with appropriate standards, specifications, guidelines and industry practice;
- details of any non-evidence-based assumptions, particularly those on which any calculations are based (e.g. fatigue life);
- the design and operation of any control system (electrical, electronic or other, programmable or otherwise);
- the structural/mechanical safety of the amusement device, including any theming which would present a risk if it were to fail;
- the suitability of the containment system (and the adequacy of any passenger restraints included as part of this system);
- the suitability of any railings, fencing and guarding;
- the operating instructions, which should be clear, complete and sufficiently detailed, including any restrictions on use, e.g. component fatigue lives, passenger speeds, weather etc.;
- access and egress arrangements e.g. for evacuation and maintenance work;
- the suitability of the initial test schedule;
- the inspection and maintenance schedules, including the NDT schedule and that they are sufficiently detailed.
