Made up of only about a person imperial pint (0.fifty seven L) they ended up of restricted use.
Loaded Stream: An alkali metal salt Option added to h2o to decreased its freezing point to about −40 °C (−40 °File). Loaded stream is basically concentrated wet chemical, discharged by way of a straight stream nozzle, meant for course A fires.
