WARNING
●
All personnel must leave the engine room immediately upon activation
of the Halon 1301 Fire Suppression System Alarm. System discharges
60 seconds after activation. Evacuating personnel must secure the doors
as they evacuate the area.
●
A waiting period of at least 30 minutes is required to ensure that the
area has cooled and that the fire will not reignite upon entry of personnel.
When a hatch or door is opened or the ventilation system is started,
oxygen enters the area and dilutes the Halon.
●
Do not reenter the space where Halon has been used to extinguish a fire
unless you are wearing an oxygen breathing apparatus (OBA). Wear the
OBA until the atmosphere is certified safe. Anyone suffering from the toxic
effects of Halon 1301 vapor should immediately move or be moved to
fresh air.
