One of the major causes of damage/destruction of constructed facilities in particular buildings in Tanzania is fire. Of recently, several cases of fire outbreaks have caused serious destruction to buildings and other properties especially in Dar es Salaam. It is well known that fire damages can be significantly reduced if appropriate fire prevention and protection measures are taken into account during the design and construction stages of buildings. In this manuscript, therefore, observations and results of investigation carried out to determine the provisions of fire safety measures in the design and construction of buildings in Dar es Salaam are presented. It has been established that in some of the buildings investigated, fire safety measures have not been adequately provided and in case of fire outbreaks serious damages are likely to occur.
