Tests and Inspections

Provisions should be made to allow testing on a scheduled basis in accordance with applicable codes

and standards to verify:

1. All limit switches are operable and functioning as required.

2. All controlling signals from sensing devices are within specifications.

3. All control switches are operable.

4. All indicating instrumentation is operable and within specified accuracy.

5. All annunciators are operable as specified.

6. All electrical interlocks are operable and functioning as required.

7. Proper performance of all load cells.

8. All motors are operable and functioning as required.

9. Hoist load and brake tests.

10. Any special function that is unique to the equipment.

Assembly and Disassembly Techniques

All systems should be of modular construction, if possible, to facilitate maintenance. Modules can

be replaced or relocated to other maintenance facilities with less potential for personnel exposure.

Systems for use in highly congested areas must also allow for modular construction to a sufficient

degree to allow for access and recovery of components.

Systems or modules of systems should provide for handling by fully protected personnel (e.g. plastic

suits) with a minimum of special requirements. Permanent lifting points are desired, and lifting slings

(ropes, cables, straps) should be avoided.

Gloved or double gloved hand compatible electrical and service connectors should be used to

facilitate connections. Sharp edges or rough surfaces are to be particularly avoided, to prevent

compromising protective clothing.

Special Handling Requirements

The handling of typically large and powerful remote equipment in confined spaces and the subsequent

maintenance of that equipment should be a design factor. The problem of live system troubleshooting

in such an environment is of particular concern. System designs should allow for methodology of

required personnel work without hazard to personnel.
