    Fire suppressant

    Sometimes a dry chemicalsuppressant is used. In the aerial appliion of liquid fire suppressant materials it has been found that these substances tend to atomize when dropped from substantial elevations. On the other hand, materials of high viscosity such as clay slimes tend to resist atomization upon descent to target areas. The colloidal behavior of certain clays such as those produced in ...

  • Firedamp

    Firedamp

    Firedamp is explosive at concentrations between 4% and 16%, with most explosions occurring at around 10%. It caused many deaths in coal mines before the invention of the Geordie lamp and Davy lamp. Even after the safety lamps were brought into common use, firedamp explosions could still occur from sparks produced when coal contaminated with pyrites was struck with metal tools.
