The Health and Safety Executive is urging organisations to ensure workers' safety is paramount when resuming operations after the millennium rollover.
Tips included in the agency's new guide, The Morning After the Millennium Before, include ensuring rescue, fire and first aid arrangements are in place, before attempting to operate machinery.
The HSE advises companies to check safety systems are working properly before operating machinery and to make sure key technical staff are present.
They should also ensure equipment can be shut down safely, if electricity and other systems fail.
"Staff should not be given the opportunity to take shortcuts or make unauthorised modifications," the guide states.
It also advises employers to "be prepared and plan for the worst."
