ASBESTOS and contaminated water are listed among the dangers for Tasmanians who want to return to bushfire ravaged communities.
Police believe it is not yet safe to reopen the Arthur Highway, which is the only access road to the fire-affected Tasman Peninsula.
Tasmania's Acting Deputy Police Commissioner Donna Adams said today that there were also dangers related to asbestos-ridden buildings and contaminated water.
"We don't want people going into the area and obviously compromising their safety,'' she said.
``There are a number of safety and public health issues that need to be considered before we start bringing people back into the area.''
Police hope to finalise such plans today, and their preliminary searches of all the houses in the region for victims by the end of tomorrow.
There are still 100 people unaccounted for, and a handful of people that police hold grave concerns about following major bushfires that started on Friday.
Residents will be briefed on such dangers before they are permitted to return to their properties.
Director of Public Health and Chief Health Officer Roscoe Taylor cautioned those returning to bush-affected areas to exercise extreme caution.
``The desire to go home is understandable but it needs to be done carefully and safely to avoid serious injury,'' Dr Taylor said.
This includes being mindful of structures that can fall, sharp objects, smouldering coals, live electrical wires, leaking gas, asbestos or chemicals.
He recommends putting on protective gear before entering such a property including sturdy footwear, heavy-duty work gloves, disposable overalls with long sleeves and trousers, and a P2 face mask.
Emergency Management Minister David O'Byrne said Workplace Standards Tasmania was already involved.
