It is essential to discuss the requirements for stmc-tural protection, compartmentalization, emergency lighting, detection, alarms, call points, suppression, means of escape and signage with the applicable local authority, fire brigade or insurance company personnel before finalizing designs. 

Small-format lead-acid batteries with immobilized electrolyte are still used in some applications such as hand lanterns. Low-cost six or twelve-volt batteries (e.g. 6 Ah size) are used in child-driven toy cars and other sizes in emergency-light or alarm systems, kept on trickle-charge. Efforts are being made to produce bipolar systems which give 30 percent improvements. 

Portable valve-regulated lead-acid cells can operate in any orientation without acid leakage and find use in many different applications, such as in electronic cash registers, alarm systems, emergency lighting unit equipment, telephone boxes, switching stations, minicomputers and terminals, electronically controlled petrol pumps, cordless television sets and portable instruments and tools. 

Iron-nickel oxide batteries have been used for many years in railway lighting applications, and for motive power in industrial trucks, tractors and mine locomotives. There is some utilization of the system in emergency lighting and alarm circuits.

Luminol and diphenyl oxalate are two compounds very frequently used in a variety of classic applications from non-electric emergency lighting to the hoops, necklaces and light batons sold at fairgrounds. The reactions that causes emission are all oxidations by hydrogen peroxide. 

Until 1995, the largest fraction of Ni-Cd batteries introduced into the market was in household and electronic equipment. The emergency lighting units market has been in constant but moderate growth during the 1990 s. From 1995, the cordless power tools application has taken a dominant position for these batteries (see also Figure 4) both in consumer and professional applications. A ten to twenty percent aimual market increase has been observed during the last three years (Black Decker 2001). 

Two types of aluminium/air batteries are being developed oriented toward different applications alkaline batteries for electric vehicles, due to favourable specific energy, and saline batteries for special applications, such as, emergency lighting, reserve power, marine objects and so on.
