Basic principles of fire

The absence of any one of these elements will prevent a fire starting. Prevention depends on avoiding 

Hot surfaces Electrical equipment Static electricity Smoking materials Naked flame 

Once a fire starts it can spread very quickiy from fuei to fuei as the heat increases. 

Workpiaces have numerous sources of ignition, some of which are obvious but others may be hidden inside machinery. Most of the sources may cause an accidentai fire from sources inside but, in the case of arson (about 13% of industriai fires), the source of ignition may be brought from outside the workpiace and wiii be deiiberateiy used. The foiiowing are potentiai sources of ignition in the typicai workpiace construction site  

If it will burn it can be fuel for a fire. The things which will burn easily are the most likely to be the initial fuel, which then burns quickly and spreads the fire to other fuels. The most common things that will burn in a typical workplace are

In the present chapter, the basic principles of firee-radical chain polymerizations, i.e., chain-growth polymerizations in which the reactive centers are free radicals, will be considered in detail, focusing on the polymerization reactions in which only one monomer is involved, while polymerization reactions involving more than one monomer, referred to as free-radical copolymerization, are considered separately in Chapter 7. Chain-growth polymerizations in which the active centers are ionic are discussed in Chapter 8. 

In practice, investigating a fire in the workplace will follow exactly the same principles as described previously in this chapter. The information in this section is provided to allow those with a responsibility for the management of fire safety in the workplace to develop an understanding of the basic principles of fire investigation.
