Abstract

A monitoring system comprises a device to remotely sample the atmosphere (3) of a fire affected compartment to determine the temperature (5) and the relative concentrations of oxygen, carbon dioxide, carbon monoxide and flammable vapours (8, 9, 10, 12). A processor (14) is used to provide an indication of the safety status of the compartment (15) as safe to enter, unsafe to enter or undecided based on the determined gas concentrations and temperature.
