  • Upon receiving a signal from the incident commander
  • When the atmospheric conditions feel safe
  • As soon as they enter the structure
  • After the fire has been knocked down (correct)

    • Why should gas detection meters not be exposed to active fire conditions?

  • Because they are not designed for high temperatures
  • To avoid interference with firefighting operations
  • Because exposure to heat can damage the instruments (correct)
  • To prevent contamination of the detection sensors
