In a school science department, there is a significant number of chemicals that can cause a fire hazard.
They can broadly be divided into two groups:
1) Flammables – solids, liquids or gases that can ignite with a reasonable ease (sometimes extremely easily) or that (like alkali metals) release flammable gases easily.
2) Oxidising agents – that make less flammable substances, paper for example, much more likely to ignite.
The articles listed below contain information on how to avoid the outbreak of fire and how to deal with one (on a small scale) if it were to break out.
