In the law about fire prevention and safety in factories, you need to understand what some words mean. The part of the law that explains what these words mean is called 'Interpretation'. This Interpretation part is found in section 636B of the Local Government Act 1974, but it is no longer in use because it was repealed.

You can find out what repealed means by looking at other parts of the law, it was removed from use on 1 July 1992 by the Building Act 1991. This means that section 636B is not used anymore. The Building Act 1991 is another law that changed the Local Government Act 1974.
