The space or room containing the incinerator combustion chambers and their accompanying burners should have a fire detection and alarm system. Fire protection may be provided by automatic extinguishing means such as a water sprinkler system or a fire hose station. In particular applications, foam or powder may be more appropriate. Depending on the radiation level expected for some of the components, an automatic or remotely actuated suppression system may be required.

Fire alarm systems may be installed in buildings to satisfy one, or both, of two principal objectives, namely protection of life and protection of property. Table 9.14 outlines the types available, their primary purpose and in which areas of a building they are installed. The standard for fire detection and alarm systems in buildings is contained within BS 5839 Part 1. 

BS 5839 uses a system whereby fire detection and alarm systems are categorised according to their operating method and purpose. 

Fire detection and alarm system must be provided [13(1)(a), 4.(1)(e) and 15(2)(a) and (b)]. The type and coverage of the fire alarm would be subject to the requirements of the risk assessment. 

If equipment and procedures work as intended, fire fighting is a rather short process, because the compartment where the fire is assumed to occur is equipped with a fixed fire extinguishing system which suppresses the fire with a sufficiently large amount of water after actuation by the fire detection and alarm system. However, one major assumption of the andysis presented here was the failure of the automatic actuation of the fixed fire extinguishing system. This implies that the fire has to be extinguished by manual fire fighting means performed by the plant personnel in charge.
