Understand all associated hazard knowledge
Mezzanine floors should be compartmented from the lower storey and have a separate means of escape independent to any on the lower storey. A gallery should normally be treated as an additional storey in a building. Mezzanines and galleries may also be used for storage, resulting in a higher level of fire loading.
Raised storage areas may be defined as raised platforms, like mezzanines. However, they will not provide a separate means of escape from those provided on the floor below and they may not be compartmented from the floor below.
Raised storage areas are likely to have minimal provisions for fire resistance and may be susceptible to early collapse, particularly if high fire loads have been stored beneath the raised storage area.
