This annex sets out detailed guidance on the practical aspects of organising and managing a Scientific and Technical Advice Cell ( STAC). The template is based on a model originally developed by Health Protection Scotland with the NHS Boards.
A STAC may be established in any circumstances where it is likely to be helpful and need not be reserved only for situations where the full strategic level arrangements are enacted. Local area arrangements for establishing a STAC should therefore be sufficiently flexible to allow for the formation of a STAC for various types of scenario ( e.g. where expert advice is required for tactical or operational level action).
Where appropriate, a STAC should be established at an early stage of development in an emergency to allow time to anticipate the range of impacts which could occur. The STAC therefore has a proactive anticipatory role and should actively consider "what if" scenarios, rather than being solely reactive.
