A self-contained breathing apparatus or SCBA is a device worn by workers to provide portable, breathable air in an IDHL-environment.

Thermal imaging cameras use infrared technology to detect the temperature differences or levels of heat objects emit and displays a thermal image of the objects in real time.

Compact gas monitors that measure gas levels to alarm when dangerous conditions exist so that a user knows if the environment is IDLH or when personal protective equipment is needed.
