Personnel from the Isle of Wight Fire and Rescue Service, Hampshire Fire and Rescue Service, Hampshire Constabulary and English Heritage and will be taking part in the exercise, which will start at 0915 and is expected to last until 1600. Red Funnel Ferries will also be supporting on the exercise with transporting fire vehicles to the island.
The exercise scenario will include imitation artefacts being removed safely from a first floor room, not usually open to the public.
During the exercise, Osborne will remain open to visitors, with minimal restrictions to exterior routes around the house. The visitor experience inside the house will be unaffected.
Chief Officer of Hampshire Fire and Rescue Service and the Isle of Wight Fire and Rescue Service, Dave Curry said:
"The scenario we are testing will look pretty realistic, so I’d like to advise local residents and the public that this is just an exercise.
"Exercises like this are a vital way of practising our skills and ensuring that we are ready, should there ever be a major incident on the Island."
There will be a number of fire service vehicles travelling from Eastleigh in Hampshire, across to East Cowes on the Isle of Wight. Every effort will be made to keep any disruption to a minimum.
Media will not be permitted at the exercise but a media package including a press release, photos and footage will be sent out by HFRS early next week.
