Materials used in internal construction of premises8

1

Any material which is used in the construction of an internal wall or ceiling in any public area must be of limited combustibility.

2

To inhibit the spread of fire within the premises, any material which is applied to the surface of an internal wall or ceiling in any public area must—

a

adequately resist the spread of flame over the surface; and

b

have, if ignited, either a rate of heat release or a rate of fire growth, which is reasonable in the circumstances.
