  • Equipment is selected to be suitable for the intended purpose, particularly with regard to the site conditions in which the equipment will be used.
  • Appropriate maintenance is carried out and any associated logs kept up to date.
  • Specific Health and Safety risks associated with the equipment are considered and where appropriate:
    Use of the equipment is restricted to competent, nominated persons.
    Maintenance/Servicing is restricted to designated persons with the appropriate competence.
  • Persons who will use, supervise and manage equipment receive information and instruction on training to cover
    The conditions and circumstances in which the equipment may be safely used.
    The methods by which the equipment is to be used including operating procedures.
    Actions to be taken in the event of abnormal situations including emergencies.

1.32 Hygienic Maintenance.

It is most important for all contractors, especially those engaged in maintenance operations who may be required to work in areas where computing equipment is being handled, to recognise that the way they organise and conduct their work can present a threat to the product. The threat arises from several sources:

A. Accidental contamination of the product or equipment by foreign bodies for example: flakes of paint, dust, nuts, bolts, screws, gaskets and "O" Rings etc.

B. Accidental contamination by failure to operate according to a reasonable code of practical hygiene.

C. Use of unsuitable materials to lubricate or otherwise treat the surfaces of equipment.

It is therefore essential that due consideration is given to the way the work is to be done before starting, so that adequate precautions are taken to prevent contamination from all foreseeable sources.
