Our inspection service was established in December 1965.
Since then we have successfully completed thousands of inspection and
debris-retrieval assignments. All work of this type is carried out by
fully-experienced operators using a wide range of specialist equipment.
Witnessing of inspections by a responsible representative of the client is
encouraged. Wherever possible we insist that covers are fitted, in our
presence, immediately following inspection. Details of any factors which may
influence the security of the plant are recorded. An inspection report is
submitted to the customer and two further copies are held by Jackson
Electronics. These are stored in separate locations to protect against loss
of information by fire. All records are retained for a period of ten years. |
