(1) If it appears to
the Chief Executive that the nature or scale of an emergency that has
occurred, is occurring or is about to occur, is such that it should be
declared to be a public health incident, the Chief Executive may, with the
approval of the Minister, declare the emergency to be a public health
incident.
(2) A declaration
under this section—
(a) may
be made orally (but if made orally must, as soon as is reasonably practicable,
be reduced to writing and a copy provided to the Minister); and
(b)
subject to this section, remains in force while response operations are being
carried out in relation to the emergency (but not for a period exceeding
12 hours).
(3) The
Chief Executive may, at any time, revoke a declaration under this section.
